This paper studies the design effect of counting rules, for linking deaths to housing units where they are enumerated in the survey, on the sampling variance of dual system and single system estimators of death registration completeness. It investigates estimators based on conventional rules that uniquely link each death to a single housing unit as well as estimators based on multiplicity rules which permit deaths to be linked to more than one housing unit. Sampling variance formulas are derived containing parameters that reflect the efficiency of the counting rule. Estimates of these parameters for different counting rules are compared utilizing information that was collected in a mortality survey experiment. Finally, the design of a national death registration test is considered and the sample size implications of different counting rules are compared. [ABSTRACT FROM AUTHOR]

This paper has two principal aims: (1) to analyze and measure how the demographic variables-mortality, fertility, and immigration- affect the cost of education; (2) to evaluate what possibilities developing countries, such as those of Latin America, have for a rapid educational improvement. The paper relates demographic and educational variables of three different populations: Sweden, 1840-1965; the United States, 1850-1960; and Latin America, 1930-2000. Three educational variables are also cone sidered: (a) school attendance rates by sex and age; (b) distribution of students of same age by grade; and (c) cost of student by grade. Demographic changes in countries such as Sweden and the United States were favorable for the development of education. For the future, unless an increase of fertility occurs, mortality and fertility changes will not have a significant effect on the cost of education in these countries. In current less developed countries the demographic changes during the past were less favorable to educational development. A future reduction of fertility will significantly help them to achieve a higher educational level. [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]

Results of therapeutic trial of diazepam in tetanus are presented. The trial included 200 cases of tetanus—167 non-neonates and thirty-three neonates. The patients were divided into two groups and were matched as regards age, sex and severity of the disease. The cases of group I received standard treatment while the cases of group II received diazepam in addition. Over-all mortality in group I was 54% and in group II, 26%. The results were statistically significant in non-neonates and in severe degree of tetanus. The drug was well tolerated and side effects were not observed. [ABSTRACT FROM PUBLISHER]

Blacks are more likely than whites to have unwanted births. A common explanation for that difference is that blacks use less effective contraceptive methods, use contraception less effectively, and use contraception less often than whites. Analysis of data from 17 cities in our family planning evaluation project suggested that, among women living in low-income neighborhoods, the black-white difference in unwanted births was not due to (1) blacks reaching desired completed parity at younger ages than whites, (2) differences in age or parity in our black and white samples, (3) black-white differences in current use of physician-administered contraception, or (4) blacks being more likely than whites to adopt physician-administered contraception after having an unwanted birth. Black-white differences which might have contributed to relatively more unwanted births among blacks were (1) blacks desired fewer children, (2) blacks were less likely than whites to use nonphysician-administered methods and more likely than whites to use no contraception, and (3) blacks had higher failure rates than whites subsequent to the adoption of physician-administered methods and when not using those methods. Comparisons are made with the 1965 and 1970 National Fertility Studies, and program implications of the findings discussed. [ABSTRACT FROM AUTHOR]

The effects of education on current migration propensities in the United States are examined for each age group, and an estimate is made of how these age-specific differentials cumulate over a lifetime in determining the number of times that individuals at different educational levels can expect to move over the course of their lives. The independent effects of age, education, and occupation are also examined. Two other sections investigate trends in educational selectivity of migration in the United States and international comparisons of occupational differences in migration. [ABSTRACT FROM AUTHOR]

Differences in the distribution of population within and across metropolitan areas are seen as a product of the development of the metropolis during different transportation epochs. Age cohorts of census tracts in Cleveland, Ohio, may be split into three groups of development patterns based on the time of their early development: (1) before the development of the automobile, (2) during the early period of the auto's diffusion to the population, and (3) during the period of the mass diffusion of the auto. Patterns of population concentration and congestion across metropolitan areas are heavily selective of places with large population growth before the development of the streetcar and the automobile. More recent population growth has had little effect on population congestion but has led to a deconcentrated metropolis. [ABSTRACT FROM AUTHOR]

An attempt is made to investigate the educational differentials between various types of interdivisional migrants and nonmigrants in selected Standard Metropolitan Statistical Areas (SMSA's) of the United States. The analysis is carried out for four color-sex groups standardized for age. We have been able to identify three distinct patterns of migration differentials by education, that is, the J-shaped, the U-shaped, and the reverse J-shaped distributions. The tendency for migrants to be better educated than nonmigrants, by and large, has received support from the data we have analyzed. Wherever this tendency has not been confirmed, the main factors which, we believe, have influenced the differentials are the proportion of foreign-born whites, the geographic location of the places of origin and destination, and the differences in levels of educational attainment.

There was an impressive increase between 1965 and 1970 in the prevalence of contraceptive sterilization, an increase that accelerated in the later years of the period and was shared in by virtually all subgroups considered, Among couples in 1970 for whom sterilization had been an option (recognizing that it is a terminal method), about one of every five had chosen this method of contraception. About half of all sterilizations were vasectomies, though vasectomies have outnumbered tubal ligations in recent years. Differentials in prevalence and in increases during 1965-1970 are reported for a number of life-cycle and social variables. In addition, a profile of the contraceptive sterile is presented for recent sterilizations. Significant proportions are relatively young and, of low parity at the time of sterilization. In the context of the continued diffusion of the pill and IUD and increases in legal abortion, the net demographic effect of increasing sterilization is regarded as low, though sterilization is an important component of an effective fertility control regime.

The reduction of population growth rates through family planning programs is being attempted in many of the developing nations of the world. This activity lends itself aptly to mathematical modeling. Building from the well-known difference equation model of population growth, a model is constructed which integrates population dynamics, program activities, and resource consumption. The model may be used predictively to assess the outcome of various program activities. Alternatively, it may be used to determine the pattern of activities which yields the greatest reduction in births under the projected resource constraints. A further use of the model is the identification of the parameters to which predictions are most sensitive; such information provides valuable insights to those gathering the input data. The model is here applied to a family planning program currently in progress. An evaluation of the feasibility of that program's goals is provided, as well as information on limiting resources, data sensitivity, and the most important ages for contraceptive acceptance.

Between 1960 and 1970 blacks, as well as whites, improved their socioeconomic status. Among both races, educational attainment increased, the occupational distribution was upgraded, and real purchasing power rose markedly. In almost every comparison, the gains were somewhat greater among blacks than among whites and thus most indicators of racial differentiation declined. Nevertheless, the changes of this decade failed to eliminate racial differences with regard to socioeconomic status. In all comparisons, except for the income of certain groups of women, blacks were at a disadvantage when compared to whites both at the start and at the end of this decade, and very large racial differences remain. Further socio- economic progress by blacks during the 1970s will probably not eliminate racial differences. The article concludes by relating the socioeconomic trends to such other aspects of race relations as integration, governmental policy, and the attitudes of whites and blacks. [ABSTRACT FROM AUTHOR]

Patterns of family size, family stability, and timing of family formation characteristic of Mexican-Americans are contrasted with those of Japanese-Americans, and consequences of their demographic differences for group achievement are explored. Mexican-Americans are found to have a demographic system marked by young ages at marriage, young ages at beginning of childbearing, high rates of reproduction, and high rates of marital instability. Japanese-Americans display just the opposite pattern of behavior on each of these variables. Using existing research on determinants of individual achievement, reasons are then suggested why the demographic environment encountered by Japanese-American youth is more conducive to educational and economic achievement than is that encountered by Mexican-American youth.

In terms of quantitative comparative data Middle Eastern countries report systematically the lowest female participation rates in economic activities outside of agriculture. This behavior represents a deviation from the current experience of other developing nations and from the historical experience of the now-industrialized West. Using comparative data on female employment patterns in Latin American countries which are at roughly a similar stage of economic development, it is shown that the low level and particular character of women's involvement in the work force in the Middle East can be explained by institutional arrangements contingent upon aspects of social structure. Five countries are selected for intensive analysis: Chile, Mexico, Egypt, Morocco and Pakistan. One major aspect of social organization and its cultural adjuncts is emphasized: The interplay between the volitional avoidance by women of certain occupational sectors because of the social stigmatizing aspect and the prohibition of occupational opportunities imposed by males. The combined effects of this tradition of female seclusion and exclusion are confirmed by the detailed analysis of the structure of the non-agricultural labor force: Middle Eastern women are absent systematically from occupational and industrial sectors of employment which involve public activity and presuppose contact with males.

This study empirically investigates the relationship between the economic structure of populations and their level of fertility, using data from censuses recently conducted in some 50 nations. Findings show that high rates of female labor force participation outside the home and low rates of economic activity of children depress a society's fertility level, as measured by the crude birth rate or the child-woman ratio. It is also hypothesized, but not confirmed, that the per cent of unpaid family work- ers in a society is positively related to its fertility level. A model is presented that treats these three components of economic structure as intervening variables through which the exogenous variables, urbanization, industrialization, and education, operate in influencing the fertility level of a society.

The primary objective of this study is to present an explanation of the interstate migratory movements of white and nonwhite persons which occurred over the period 1955-1960. The study is similar to several other recent studies in that we estimate the magnitudes in which various factors have influenced interstate or interregional migration in the United States. It differs from earlier studies in two important respects. First, we estimate and compare the magnitudes in which certain factors have influenced both white and nonwhite interstate migration. Second, unlike previous studies, many of which have made "country-wide" estimates of the determinants of migration, we have disaggregated data to the state level and obtained white and nonwhite "migration elasticities" for every state. These elasticities are in turn used to test several additional hypotheses relating to racial and regional differences in the elasticities themselves. We argue that discrimination against nonwhites and/or differences in "social milieu" between South and nonsouth provide a unifying explanation for most of the observed differences in white and nonwhite migration elasticities.
