It is widely believed that structural variables such as inequitable land distribution, lack of rural employment opportunities, and rural-urban wage and amenity gaps influence population movements in developing countries. Yet quantitative evidence is scant. In this paper a multilevel model is used to investigate the effects of individual-, household-, and areal-level factors on rural-urban out-migration in the Ecuadorian Sierra. Data from a detailed survey carried out in 1977-1978 and from government macro-areal statistics are used to investigate factors affecting the out-migration of youths aged 12-25. Preliminary conclusions are presented on the usefulness of multilevel models in studying migration and policy implications for Ecuador. [ABSTRACT FROM AUTHOR]

This paper estimates ever-married birth rates by age and duration since first marriage and ever-married total fertility rates for the Republic of Korea, derived by applying an extension of the own-children method of fertility estimation to the 1975 and 1980 censuses. Since each census provides annual estimates for the 15-year period previous to enumeration, there is a ten-year period of overlapping estimates that facilitates checks for consistency and accuracy. Comparisons are also made with estimates derived from the 1974 Korea National Fertility Survey, which was part of the World Fertility Survey. The method works well, except in its application to the 1975 Census where the evidence suggests considerable misreporting of age at first marriage because of the way the question was asked and coded. Results confirm that ever-married fertility fell substantially in Korea between 1961 and 1980, with a temporary resurgence in the late 1960s and early 1970s. Ever-married fertility rose at younger ages and shorter durations and fell at older ages and longer durations. Ever-married fertility differentials by urban-rural residence and by education were usually in the expected direction, with urban fertility generally lower than rural fertility and the fertility of those with more education usually lower than the fertility of those with less education. Differential ever-married fertility by urban-rural residence and education declined over the estimation period. [ABSTRACT FROM AUTHOR]

This paper examines inter-provincial female migration in Chile for the 1965--1970 period, with a view to describing socioeconomic characteristics of migrant women and to determining differences and similarities in age, educational level, occupation, and type of move (first, return, or repeat) between movers to the capital and to other urban areas. Data are from a five percent sample of the 1970 Chilean census. Findings reveal that non-return migrants to other urban areas are differentiated from those to Santiago by an older age structure, higher educational levels, higher status occupations, and are more likely to be making a second (or higher-order) move. Moreover, educational measures suggest that recent female migration to urban Chile is more prevalent among the upper than the lower strata of the society. [ABSTRACT FROM AUTHOR]

This paper introduces an analytic framework that can be used to assess the relationships between individual movement differentials and place characteristics, on the one hand, and aggregate mobility levels and city-suburb population change (in size or composition), on the other. Application of this framework using census data for individual metropolitan areas allows the analyst to decompose population changes due to net migration into contributing mobility streams and their component rates which are subject to unique community and individual influences. The paper provides both theoretical and empirical rationale for the framework, illustrates its use with 1970 census data, and discusses its implications for empirical research on city-suburb population redistribution.

In 1965, Warner developed an interviewing procedure designed to eliminate evasive answer bias when questions of a sensitive nature are asked. He called the procedure "randomized response." The authors have been studying the technique for several years and, in this paper, are re- porting some of the estimates of induced abortion in urban North Carolina using randomized response. Estimates of the proportion of women having an abortion during the past year among women 18-44 years of age are reported. For the study population indices were developed relating induced abortion to total conceptions for whites and nonwhites. The illegal abortion rate per 100 conceptions was estimated to be 14.9 for whites and 32.9 for nonwhites. Estimates of the proportion of women having an abortion during their lifetime among women 18 years old or over are also shown, Among ever married women, the proportion having an abortion during their lifetime declined as education increased. Estimates were high for women with 5 or more pregnancies. Most of the respondents stated that they were satisfied that the randomized response approach would not reveal their personal situation. Furthermore, they did not think their friends would truthfully respond to a direct question regarding abortion. [ABSTRACT FROM AUTHOR]

The objective of this paper is to provide, for the first time, comparative estimates of racial residential segregation of blacks, Hispanics, and Native Americans in nonmetropolitan and metropolitan places in 1990 and 2000. Analyses are based on block data from the 1990 and 2000 U.S. decennial censuses. The results reveal a singularly important and perhaps surprising central conclusion: levels and trends in recent patterns of racial segregation in America's small towns are remarkably similar to patterns observed in larger metropolitan cities. Like their big-city counterparts, nonmetropolitan blacks are America's most highly segregated racial minority--roughly 30% to 40% higher than the indices observed for Hispanics and Native Americans. Finally, baseline ecological models of spatial patterns of rural segregation reveal estimates that largely support the conclusions reached in previous metropolitan studies. Racial residential segregation in rural places increases with growing minority percentage shares and is typically lower in "new" places (as measured by growth in the housing stock), while racially selective annexation and the implied "racial threat" at the periphery exacerbate racial segregation in rural places. Our study reinforces the need to broaden the spatial scale of segregation beyond its traditional focus on metropolitan cities or suburban places, especially as America's population shifts down the urban hierarchy into exurban places and small towns.

In many Indian societies couples have consistently reported strong preferences for sons. However, these preferences are not always reflected in either contraceptive use or fertility. Previous studies refer mainly to the period 1961-1970, when contraceptive use was minimal, there was little evidence of conscious control among couples, and the majority had large families. This paper, using samples of rural and urban women interviewed during 1979-1980, shows that the sex of previous children at various attained parities has a significant effect on subsequent fertility. We conclude that son preference now has an effect because family size has decreased and contraceptive use has increased. The disappearance of sex preference would reduce overall fertility modestly.

Although there is a historical series on the urban population of the United States for the period covered by national population censuses (1790-1980), no corresponding historical series exists on the population in metropolitan areas or urbanized areas. This paper presents a time series on the population in highly urbanized counties. The series, which combines the metropolitan-area and urbanized-area concepts, facilitates compilation of social, economic, and other data and permits quantification of the effect of reclassification of territory on the growth of this population. The growth of the population in highly urbanized counties in the United States is discussed briefly, with an emphasis on the effect of reclassification. [ABSTRACT FROM AUTHOR]

This paper examines the probabilities of first marriage dissolution in Canada, using the marital history data collected from a national sample of women in their reproductive years. It is found that age at marriage, year of marriage, cohabitation before marriage, a premarital birth or conception, urban-rural place of residence, and religiosity are all significantly correlated with marriage dissolution. Religion and education, on the other hand, do not seem to affect the marriage dissolution probabilities when other factors are controlled. Canadian patterns are not too different from patterns in the United States. [ABSTRACT FROM AUTHOR]

This paper proposes and carries out a two-stage analysis of the determinants of desired family size, using data gathered from a sample of women in the city of Ilorin, Nigeria. The analysis first focuses on differences between women who report numerical family size desires and those who report nonnumerical desires. Findings suggest that there are important differences between these two groups, but there is little variation in the actual number reported by those expressing numerical desires. Implications of these findings for survey design are discussed. In particular, the practice of forcing numerical responses by instructing interviewers to probe when women report nonnumerical desires is questioned. [ABSTRACT FROM AUTHOR]

Survival analysis can be used to study the association between a set of explanatory variables and the age at which an event of interest, say weaning, occurs. As retrospectively reported age data often contain serious reporting errors, many analysts prefer to use current status data. In this paper, the authors discuss two approaches to fitting survival models to current status data from the Pakistan Fertility Survey. A generalized linear model approach, using constrained maximum likelihood estimates, proves computationally expensive, so a transformation of the baseline hazard is modeled, using spline function.

Contemporary populations frequently space the births of children, and also attempt to stop childbearing after achieving a desired family size. While stopping behavior was evident in European populations in the late nineteenth century, little is known about the degree to which they attempted to space their children at specific interval lengths. This paper compares spacing patterns among various groups of white U.S. women in 1900, who were distinguished by varying family sizes and levels of fertility control. On the whole, there is little evidence of childspacing differences among native white populations, except for some very low parity women. The findings support the continued analysis of age patterns of fertility as the major means for determining the onset of conscious family limitation. [ABSTRACT FROM AUTHOR]

It is generally accepted that socioeconomic differentials in fertility are minimal among urban couples with nonfarm origins -- two generation urbanites. In this paper, we replicate Duncan's (1965) analysis to see if the two generation urbanite hypothesis holds for more recent cohorts of American women. In four cohorts of women, drawn from three recent fertility surveys, we find no support for the two generation urbanite hypothesis. It appears that the links between farm background, socioeconomic status and fertility were different for the low fertility cohorts of women born in the early 1900's and the more recent cohorts of women who experienced the baby boom.

Several authors have argued that increased work opportunities for women have helped to produce a reduction in the average age at marriage in the United States. This paper tests this proposition on data for the 100 largest SMSA's in 1960. Using ordinary least-squares regression, we find that areas of relatively attractive female employment opportunities had relatively low proportions of women ever married in the age interval 22-24. Other variables significantly related to the proportion married in an SMSA are its sex ratio, percent Catholic, and number of inhabitants. A decline in the sex ratio and improvements in female employment opportunities appear to have been equally influential in producing declines in proportions married between 1960 and 1970.

In this paper an attempt has been made to study differential fertility by urban-rural and regional classifications, using data obtained from complete tabulations of the 1963 Census of Population, the four rounds of the Socio-Economic Survey conducted from November 1969 to October 1970, and the Registrar General's Department. The analysis of current fertility indicates that the traditional pattern of lower urban fertility relative to rural held true in both 1963 and 1970 and also shows a narrowing of the differentials. The country was divided into four zones on an agro-climatic basis for regional analysis. A consistent ranking of the zones in relation to current fertility emerges in both 1963 and 1970. Changing patterns of age-specific fertility and age-specific marital fertility are discussed. Data on average size of family by urban-rural and regional classifications are also analyzed. An attempt has also been made to identify some of the possible causes for the differentials observed. [ABSTRACT FROM AUTHOR]

Using an ecological perspective, one aspect of the relationship of social distance and physical distance is analyzed in the three largest cities in Israel. The principal aim of the paper is to examine ethnic (country of origin) residential segregation as an indicator of social patterning within the society. Despite the different demographic, topographical and functional characteristics of the three cities, fairly similar patterns of ethnic segregation are found using the technique of Smallest Space Analysis (SSA-I) to analyze index of dissimilarity matrices. Patterns of ethnic segregation are then related to the SES of sub-quarters to determine the nature of the internal structure of the cities. It is suggested that ethnicity is an important variable in the process of social stratification in urban Israel, at least insofar as ecological relationships are concerned. [ABSTRACT FROM AUTHOR]

The primary purpose of this paper is to analyze the "determinants" of migration between Standard Metropolitan Statistical Areas (SMSA's) in the United States. The magnitudes in which various factors have influenced inter-SMSA migration are estimated both for the country as a whole and for individual SMSA's. The "migration elasticities" estimated for individual SMSA's are in turn used to test several additional hypo- theses concerning migrant behavior. Other similar migration studies have found "wrong" signs or insignificant coefficients on certain variables a priori thought to play a crucial role in the migration process. Finally, we present clues to the causes of such "surprising" results. [ABSTRACT FROM AUTHOR]

An analysis of destination choices among metropolitan bound migrants in an already highly urban society is a means toward gauging trends in the urbanization process. The results of this paper indicated that destination choices were strongly influenced by SMSA size, with larger SMSAs and particularly their suburban rings attractive to migrants. This pattern suggested the further growth of the larger SMSAs, to the detriment of those smaller in size. In addition, the varied status of migrants entering the ring pointed toward its increased heterogeneity. Yet, among small SMSAs, the central city received more and higher-status migrants than the ring. Here, destination choice was also linked to similarity to the migrant's past residence. Regional differences emerged, and a closer examination of small and very large SMSAs suggested that destination choices were influenced by previous patterns of urban growth. [ABSTRACT FROM AUTHOR]

A study of the expressed preferences of four different ethnic groups in the Los Angeles metropolitan area shows strong desires for own-race combinations in the ethnicity of neighborhoods that individuals say they would choose when seeking a new residence. The results also show that Anglos are not the only group to practice "avoidance" of other racial/ethnic neighborhoods, although avoidance behavior by Anglos is the strongest. Because the issues of racial composition are socially sensitive, additional tests examined the relationship of preferences to behavior. Although many behaviors generally follow expressed preferences, members of households who expressed "no preference" also were found to largely choose own race neighborhoods. The results of this study suggest that the expressed preference for own race/own ethnicity, in combination with short-distance local moves, is likely to maintain present patterns of separation in U.S. metropolitan areas.

Residential segregation has traditionally been measured by using the index of dissimilarity and, more recently, the P* exposure index. These indices, however, measure only two of five potential dimensions of segregation and, by themselves, understate the degree of black segregation in U.S. society. Compared with Hispanics, not only are blacks more segregated on any single dimension of residential segregation, they are also likely to be segregated on all five dimensions simultaneously, which never occurs for Hispanics. Moreover, in a significant subset of large urban areas, blacks experience extreme segregation on all dimensions, a pattern we call hypersegregation. This finding is upheld and reinforced by a multivariate analysis. We conclude that blacks occupy a unique and distinctly disadvantaged position in the U.S. urban environment. [ABSTRACT FROM AUTHOR]

This study examines individual out-migration in Venezuela as a function of personal attributes and place characteristics indexing development, using logistic regression. The likelihood of out-migration varies inversely with age and directly with educational attainment and is higher for females and persons in places with more traditional socioeconomic structures and greater levels of population pressure; but place characteristics also affect the role of personal attributes. As a step toward elaborating a development-migration paradigm, of continuing concern is the proper representation of development and whether, in any case, development is only an artifact of public policy.

Urban scholars and planners look to evidence of recent gains in the number of nontraditional households as a potential source of increase to the population sizes and tax bases of declining central cities. While it is now well established that substantial gains in the numbers of small, nontraditional households have occurred since the 1950s, it has not been demonstrated that: (a) these households are more likely to relocate in the city than traditional family households (husband-wife with children under 18); or (b) their cityward relocation patterns will significantly alter trends toward smaller city household populations. This paper addresses these questions by examining changes in city-suburb migration stream rates by household type over periods 1955-60, 1965-70 and 1970-75 for large metropolitan areas, and assesses their implications for potential changes in the aggregate sizes of city household populations.

Recent research has suggested that the position of many urban migrants compares favorably with that of urban natives. This generalization is refined by referring to three key distinctions: migrants from rural versus urban destination. In Thailand in the early 1970s, migrants to smaller urban centers, especially the more experienced migrants, are economically more successful than migrants to the large metropolitan centers and in some cases are more successful than urban natives. Reasons for this pattern are discussed. [ABSTRACT FROM AUTHOR]

Residential segregation among Spanish Americans, whites and blacks is measured in the 29 largest U.S. urbanized areas. Results show that Spanish Americans are much less segregated from whites than are blacks and are less concentrated within central cities. Spanish-white segregation also tends to be much lower in suburbs than in central cities, while back-white segregation is maintained at a high level in both areas. Segregation of Spanish Americans from whites is found to decline with generations spent in the United States. Finally, the relative proportion of Spanish who live in a central city and the relative number of Spanish who are foreign stock, are both highly related, across urbanized areas, to variations in the level of Spanish-white segregation.

Data from the 1975 Current Population Survey confirm that, during 1970-1975, there was a reversal of the traditional net migration stream between metropolitan and nonmetropolitan areas in the United States. During this period, there was net in-migration of 1,600,000 persons to nonmetropolitan areas, in contrast to net out-migration of 350,000 persons from these areas in 1965-1970. Reversal was caused by a 12 percent decrease in the number of nonmetropolitan out-migrants and a 23 percent increase in the number of SMSA residents moving to nonmetropolitan territory over 1965-1970 levels. While some changes in the size of migration streams were due to changes in age structures and population bases in metropolitan and nonmetropolitan areas, they were caused primarily by real shifts in out-migration propensities at practically all ages in both areas.

The article focuses on the variations in urban population structure in the U.S. cities over the period of twenty-years from 1940 to 1960. Two cities, Rochester and Seattle, serve as case studies for this analysis of variation. The study focuses on the relationships between population structures, that is, the age and sex composition of census tract populations, and other social and demographic variables. Population structure was singled out for study as it reflects the dynamic processes of urban growth and change, in terms of the natural demographic factors of births and deaths, as well as the possibly more important selective migration of population. Population structure forms the basis upon which community social organization is constituted. There exist several dimensions to the study of change in census tract populations. The correlation of deviational changes not only permits an investigation of perhaps the most crucial aspect of change, the relationship between velocities of change, but also encourages the inspection of all six intercorrelations between the basic data.

A long literature in demography has debated the importance of place for health, especially children's health. In this study, we assess whether the importance of dense settlement for infant mortality and child height is moderated by exposure to local sanitation behavior. Is open defecation (i.e., without a toilet or latrine) worse for infant mortality and child height where population density is greater? Is poor sanitation is an important mechanism by which population density influences child health outcomes? We present two complementary analyses using newly assembled data sets, which represent two points in a trade-off between external and internal validity. First, we concentrate on external validity by studying infant mortality and child height in a large, international child-level data set of 172 Demographic and Health Surveys, matched to census population density data for 1,800 subnational regions. Second, we concentrate on internal validity by studying child height in Bangladeshi districts, using a new data set constructed with GIS techniques that allows us to control for fixed effects at a high level of geographic resolution. We find a statistically robust and quantitatively comparable interaction between sanitation and population density with both approaches: open defecation externalities are more important for child health outcomes where people live more closely together.

Although the trend toward greater ethnoracial diversity in the United States has been documented at a variety of geographic scales, most research tracks diversity one scale at a time. Our study bridges scales, asking how the diversity and segregation patterns of metropolitan areas are influenced by shifts in the racial/ethnic composition of their constituent places. Drawing on 1980-2010 decennial census data, we use a new visual tool to compare the distributions of place diversity for 50 U.S. metro areas over three decades. We also undertake a decomposition analysis of segregation within these areas to evaluate hypotheses about the roles of different types of places in ethnoracial change. The decomposition indicates that although principal cities continue to shape the overall diversity of metro areas, their relative impact has declined since 1980. Inner suburbs have experienced substantial increases in diversity during the same period. Places with large white majorities now contribute more to overall metropolitan diversity than in the past. In contrast, majority black and majority Hispanic places contribute less to metropolitan diversity than in the past. The complexity of the patterns we observe is underscored through an inspection of two featured metropolises: Chicago and Dallas. [ABSTRACT FROM AUTHOR]

Despite a well-established literature investigating race-related predictors of riot incidence, the racial aftermath of riots remains unexamined. In this study, I use the 1960s U.S. race riots to investigate trends in black residential segregation levels following large-scale riot activity in seven major U.S. cities. I use a novel approach--namely, synthetic control matching--to select a group of cities against which segregation trends can be compared. I find that levels of black segregation rose in 1970 for four of the seven cities, but these increases disappeared in 1980 and 1990 except in Detroit. These results mask differential trends at lower geographic levels: suburban neighborhoods in affected areas experienced larger and longer-term increases in segregation, particularly in traditionally hypersegregated cities in the Midwest and Northeast.

In some contemporary populations, fertility levels appear to plateau, with women maintaining a consistently high level of fertility for a relatively extended period. Because this plateau does not reflect the historical patterns observed in Europe, the focus of most studies on fertility patterns, mechanisms underlying the plateau and the reinstatement of a decline have not been fully explored and are not fully understood. Through the construction of fertility histories of 25,000 women using multiple years of health survey data, we analyze some of the components of stalled fertility as they pertain to Guatemala, the only Central American country to have experienced a stalled fertility decline.

Drawing on novel survey data of Milwaukee renters, this study documents the prevalence of involuntary displacement from housing and estimates its consequences for neighborhood selection. More than one in eight Milwaukee renters experienced an eviction or other kind of forced move in the previous two years. Multivariate analyses suggest that renters who experienced a forced move relocate to poorer and higher-crime neighborhoods than those who move under less-demanding circumstances. By providing evidence implying that involuntary displacement is a critical yet overlooked mechanism of neighborhood inequality, this study helps to clarify why some city dwellers live in much worse neighborhoods than their peers.

This study explores the role of early-life education for differences in cognitive functioning between men and women aged 60 and older from seven major urban areas in Latin America and the Caribbean. After documenting statistically significant differences in cognitive functioning between men and women for six of the seven study sites, I assess the extent to which these differences can be explained by prevailing male-female differences in education. I decompose predicted male-female differences in cognitive functioning based on various statistical models for later-life cognition and find robust evidence that male-female differences in education are a major driving force behind cognitive functioning differences between older men and women. This study therefore suggests that early-life differences in educational attainment between boys and girls during childhood have a lasting impact on gender inequity in cognitive functioning at older ages. Increases in educational attainment and the closing of the gender gap in education in many countries in Latin America and the Caribbean may thus result in both higher levels and a more gender-equitable distribution of later-life cognition among the future elderly in those countries.

This article examines the ways in which mixed-nativity marriage is related to spatial assimilation in metropolitan areas of the United States. Specifically, we examine the residential patterns of households with a mixed-nativity-and, in some cases, interracial-marriage to determine whether they are less segregated from the native-born than entirely foreign-born households. Using restricted-use data from the 2000 census, we find that compared with couples in which both spouses are foreign-born, mixed-nativity couples tend to be less segregated from various native-born racial and ethnic groups. Further, among both foreign-born Asians and Hispanics, those with a native-born non-Hispanic white spouse are considerably less segregated from native-born white households than from other foreign-born Asian and Hispanic households. We also find that even though nativity status matters for black couples in a manner consistent with assimilation theory, foreign-born and mixed-nativity black households still each display very high levels of segregation from all other native-born racial/ethnic groups, reaffirming the power of race in determining residential patterns. Overall, our findings provide moderate support for spatial assimilation theory and suggest that cross-nativity marriages often facilitate the residential integration of the foreign-born.

Many studies from developed countries show a negative correlation between family size and children's schooling, while results from developing countries show this association ranging from positive to neutral to negative, depending on the context. The body of evidence suggests that this relationship changes as a society develops, but this theory has been difficult to assess because the existing evidence requires comparisons across countries with different social structures and at different levels of development. The world's fourth most populous nation in 2007, Indonesia has developed rapidly in recent decades. This context provides the opportunity to study these relationships within the same rapidly developing setting to see if and how these associations change. Results show that in urban areas, the association between family size and children's schooling was positive for older cohorts but negative for more recent cohorts. Models using instrumental variables to address the potential endogeneity of fertility confirm these results. In contrast, rural areas show no significant association between family size and children's schooling for any cohort. These findings show how the relationship between family size and children's schooling can differ within the same country and change over time as contextual factors evolve with socioeconomic development.

Theoretically, a shortage of males in a local marriage market may influence the formation, quality, and trajectory of unmarried parent relationships. To test these hypotheses, I combine city-level sex ratio data from the U.S. census with microdata on unmarried couples who recently had a child from the Fragile Families and Child Wellbeing study. A shortage of men in a marriage market is associated with lower relationship quality for unmarried parents. Male shortages are associated with lower rates of marriage following a nonmarital birth, in part because of the mediating influence of relationship quality. A shortage of men is not significantly related to the economic quality of male, nonmarital childbearing partners. [ABSTRACT FROM AUTHOR]

In the United States and other high-income countries, there is intense scholarly and programmatic interest in the effects of household and neighborhood living standards on health. Yet few studies of developing-country cities have explored these issues. We investigated whether the health of urban women and children in poor countries is influenced by both household and neighborhood standards of living. Using data from the urban samples of 85 Demographic and Health Surveys and modeling living standards using factor-analytic MIMIC methods, we found that the neighborhoods of relatively poor households are more heterogeneous than is often asserted. Our results indicated that poor urban households do not tend to live in uniformly poor neighborhoods: about 1 in 10 of a poor household's neighbors is relatively affluent, belonging to the upper quartile of the urban distribution of living standards. Do household and neighborhood living standards influence health? Using multivariate models, we found that household living standards are closely associated with three health measures: unmet need for modern contraception, attendance of a trained health care provider at childbirth, and young children's height for age. Neighborhood living standards exert a significant additional influence in many of the surveys we examined, especially for birth attendance. [ABSTRACT FROM AUTHOR]

This study examined the relationship between the use of maternal-child health (MCH) care and the use of contraceptives. The high correlation between the two may be due to the independent effect of one on the other or to an association of both with the same or similar background factors. We used structural equation models to examine the relationship between these two interventions. The data were derived from six Demographic and Health Surveys: Zimbabwe from Sub-Saharan Africa, Thailand from Asia, Egypt and Tunisia from North Africa, and Guatemala and Colombia from Latin America. The results show that in all six countries, the use of contraceptives and MCH care are significantly associated, independent of intervening factors; this finding suggests that families develop a joint demand for better-quality health and limited family size and translate these demands into action by using health services for mothers and for children and by voluntarily regulating fertility.

This study examines the patterns and predictors of housing turnovers among non-Hispanic whites, non-Hispanic blacks, Puerto Ricans, and other Hispanics in New York City during 1978-1987 to assess whether access to housing is distributed differentially by race and ethnicity. The data are taken from the triennial New York City Housing and Vacancy Survey. After controlling for household preferences, purchasing power, and quality characteristics of the housing unit, multinomial logistic regression results show the most consistent and significant predictors of turnover to be geographic and market-sector attributes. The findings suggest the presence of structural constraints in the housing market which effectively channel racial/ethnic groups to separate neighborhoods. The overall results are reminiscent of early studies of neighborhood transition by Duncan and Duncan (1957) and Taeuber and Taeuber (1965), and show that little progress has been made toward achieving equality in housing or informal social contact between racial/ethnic groups.

Remarriage is one of the most important determinants of physical and economic well-being among the widowed. The goal of this study is to estimate how hazard rates for remarriage vary among widows and widowers on the basis of both observable and unobservable characteristics. The remarriage estimates rely on nationally representative samples of widows and widowers from the Panel Study of Income Dynamics. Continuous-time hazard rate regressions indicate strong age and duration dependence effects for middle-aged widows and widowers and for older widowers. Among middle-aged widows, blacks and those with dependent children in the home have lower rates of remarriage. For middle-aged widowers, living in urbanized areas limits the prospects of remarriage. For older widowers, education and, to some extent, economic status appear to have positive effects on the remarriage rates. Overall, age and time since widowhood have the strongest and most consistent effects on remarriage rates for different widowed groups. [ABSTRACT FROM AUTHOR]

There has been much controversy about the impact of the health sector and the infant food industry on breast-feeding behavior. This study links causal factors to breast-feeding decisions, using a longitudinal survey of more than 3,000 Filipino mother-infant pairs. Most factors decreasing the likelihood that mothers will breast-feed seem to be related to family economics. Delivery in a private hospital, urban residence, high income, absence of spouse, and having worked for wages affect adversely the initiation of breast-feeding. Formula advertising and distribution of samples appear to have relatively little impact on feeding decisions. [ABSTRACT FROM AUTHOR]

Analysis of the 1986 Senegal Demographic and Health Survey reveals that mothers may be able to improve their children's survival chances by migrating from the countryside to the city. Children of urban migrants, however, continue to experience a much higher risk of mortality before the age of 5 than children of urban nonmigrants, even after the mother has lived in the city for several years. This migrant mortality disadvantage persists when controlling for numerous socioeconomic and fertility-related factors typically associated with child mortality in developing countries, which also serve as indicators of migrant selection and adaptation.

Few studies have produced the over-time observational data needed to draw valid conclusions about changes in urban homeless populations during the 1980s. One place for which such data exist is Nashville, Tennessee. An ongoing series of enumerations lends little support to Nashvillians' perception that the number of homeless in their city is growing rapidly. Enumeration results also (1) contradict expectations regarding the rise of "new homeless" groups and (2) show two types of spatial redistribution--from indoor to outdoor and core to peripheral locations--to be under way. The applicability of the enumeration methodology to other communities is discussed, as are the discrepancies between purported and measured demographic changes in homelessness.

Data from a survey of marriage patterns in central Thailand illustrate the complexity of change in marriage patterns in a developing society--the diversity of traditional patterns, the different directions of change, and the variations in current patterns. The data were collected in 1978 and 1979 from ever-married women aged 15-44 in three settings:a central plains village, established areas in Bangkok, and a Bangkok squatter settlement. Three forms of entry into marriage were identified:ceremonial marriage with parental involvement in the choice of spouse, ceremonial marriage with self-choice of spouse, and nonceremonial marriage (elopement and living together). All three forms of marriage existed in each setting, and the dominant form differed in each. In general, a family background of higher socioeconomic status led to a greater likelihood of a marriage ceremony and greater parental involvement in spouse choice. Women with more education were also more likely to marry with ceremony, but higher education for daughters was associated with less parental involvement in spouse choice. These findings suggest that marriage patterns may remain diverse in Thailand, even as further development occurs. [ABSTRACT FROM AUTHOR]

This article focuses on components of change in out-migration and destination-propensity rates of metropolitan and nonmetropolitan areas. The results indicate that changes in subgroup-specific rates were the driving force behind the changing patterns between and within these two areas. Composition effects played a secondary role, mainly counteracting the negative impact of changing rates. Although the rate of change in out-migration from metropolitan areas has been reduced and out-migration from nonmetropolitan areas declined during the most recent period, the propensity to select metropolitan areas increased over the period studied. Finally, rate-specific changes vary by age and education, indicating a change in migration's impact on population composition at origin and destination. [ABSTRACT FROM AUTHOR]

Results based on an analysis of migration streams involving the metropolitan and nonmetropolitan sectors and covering a longer time interval than previously possible indicate that efforts to describe changes in the volume of movements connecting these sectors could benefit from greater attention to other related streams as well as existing patterns of population concentration. The metropolitanization process continues but is now being affected substantially by regional redistribution trends. Regional differentials in the size of metropolitan and nonmetropolitan migration streams are declining but are still substantial, so an equilibrium balance between the metropolitan and nonmetropolitan sectors will probably not occur in the immediate future.

The article focuses on age patterns of chinese marital fertility. Chinese marital fertility in rural and urban sectors and finds unusual and distinctive patterns of transition from uncontrolled to controlled fertility. The general shape of marital fertility curves is indicative of the presence or absence of conscious limitation of the number of children. Age-specific marital fertility rates were constructed for total, urban and rural data from the One-per-Thousand Fertility Survey. In populations that do not deliberately control fertility, the age pattern of marital fertility conforms to a common pattern corresponding to the fecundity of women at different ages. For the urban population, the marital fertility transition started in 1963 in conjunction with a national birth control campaign begun the previous year. For rural China, although there are mild increases in the 1960s, rapid transition begins only in 1971. The most probable cause of the departure is the administration of China's birth control policy. In most of rural China, until 1980, newly weds and couples with one child were not constrained to control their fertility.

Using World Fertility Survey data for 15 developing countries, we estimate an equation in which the dependent variable-whether the respondent has ever used an efficient contraceptive method depends on the respondent's education and location of childhood residence. All of the coefficients of this equation, including the intercept, vary over countries. Analysis based on new methodology shows that the intercept and education effects vary as a function of national family planning program efforts and that none of the parameters of the equation depend on gross national product per capita. The results demonstrate the efficacy of multilevel analysis, provide a partial test of the theory underlying the analysis, and refocus discussion of the contributions of development and policy variables to fertility reduction.

This study examines patterns of male migration in central Italy during its transformation from an agrarian to an urban-industrial society. The Italian population registers provide data on the extent and type of emigration among more than 3,500 men (ages 10 and over) who immigrated to the commune of Casalecchio di Reno, bordering the city of Bologna, from 1865 to 1915. Demographic and social differentials in overall rates of emigration and their relation to places of origin and destination are measured. The implications of these results for an understanding of population mobility are discussed. [ABSTRACT FROM AUTHOR]

The article presents a study examining possible changes in the extent of the turnaround in growth patterns between metropolitan and nonmetropolitan areas throughout the full decade of the seventies. Early research documented that the switch from negative to positive net migration into nonmetro areas was more than just a continuation of urban sprawl and that real growth was occurring in remote rural areas. Explanations for the trend included both the economic and the non-economic factors. The most important conclusion to be drawn from this analysis is that the turnaround from negative to positive net migration in nonmetropolitan areas was sustained throughout the 1970s. This shift was pervasive; it occurred in nearly all regions of the country and at all levels of population concentration. It is certain that the impact of the turnaround has been greatest in nonmetropolitan areas. In many cases, communities which had a small, declining population base experienced an influx of new residents, an expanding economic sector and novel development in the 1970s. The analysis has confirmed that amenity and recreational characteristics continued to attract migrants by the end of the decade, particularly in warmer climates, indicating that people may have been continuing to act upon a preference for rural areas.

The effects of access to piped water on the trends in child mortality and on differentials by income class are analyzed using data on surviving children and other variables in samples of urban mothers aged 20-29 in 1970 and 1976. Path analytic regression techniques are used to test a recursive model linking the supply and demand for piped water to selected household and community level variables, and to examine their joint effect on child mortality. The model's estimated parameters for 1970 and 1976 are used to analyze changes in mortality between the two dates. Increased maternal education accounts for a larger share of the mortality decline than any other single factor. Increased access to piped water also contributes to mortality decline, and such access helps to reduce the mortality differential between lower and higher income and education classes.
