This paper addresses itself to some linkages between macro-social structure (industrialization, social class), social psychological variables (husband-wile decision making), psychological variables (attitudes), and fertility. A total of 726 currently mated women with proven fertility in five Brazilian communities were interviewed to determine various attitudes, their work experience, their participation in family decisions, their fertility ideals, and actual fertility. The five communities were selected along a rural-urban-industrialization continuum to include a village, two non-industrial cities, and two industrial cities (one of which was São Paulo). Family size in the industrial cities was small in all social strata, while in the non-industrial cities family size was large in the lower strata and declined in the upper strata. Further analysis revealed that smaller family size is associated with generally higher levels of status among women-higher educational levels, greater social contacts and more skilled employment, and equality in family decision making. Our analysis supports the hypotheses that industrialization influences fertility through shifts in the social status of women, both in their work and at home. New education and work opportunities facilitate the emergence of modern conceptions of the role of women in society and egalitarian decision making in the family. These attitudes and patterns of husband-wife interaction are related to smaller family size ideals and lower fertility. [ABSTRACT FROM AUTHOR]
