Correlations in family size across generations could have a major influence on human population size in the future. Empirical studies have shown that the associations between the fertility of parents and the fertility of children are substantial and growing over time. Despite their potential long-term consequences, intergenerational fertility correlations have largely been ignored by researcher...

A method for estimating intrafamilial correlations under variable family sizes involving weightings of paired data points is introduced. Classical methods of intrafamilial correlation estimation and those in current use are outlined and critically analyzed. Extensions of the proposed estimation method to more general data structures are delineated.

Using data from the 1979 National Longitudinal Survey of Youth, I identify causal effects of marriage and cohabitation on total family income. My goals are to compare men's and women's changes in financial status upon entering unions and to assess the relative contributions of adjustments in own income, income pooling, and changes in family size. Changes in own income that are due to intrahouse...

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 e...

This paper investigates the associations between preferred family size of women in rural Bihar, India and the fertility behaviours of their mother and mother-in-law. Scheduled interviews of 440 pairs of married women aged 16-34 years and their mothers-in-law were conducted in 2011. Preferred family size is first measured by Coombs scale, allowing us to capture latent desired number of children ...

The People of India database of the Anthropological Survey of India documents 631 cultural, ecological, and economic traits of the 4635 communities to which the entire Indian population is assigned. Focusing on 1342 communities of South India, we looked for correlates of low (1 or 2 children) and high (4 or more children) desired family size (DFS) reported as the norm for any given community by...

This study tests the hypothesis that, in Nepal, measures of ideal family size mask an underlying preference for sons, making some people willing to have families larger than their ideal. Existing evidence suggests that men are likely to have stronger preferences for sons than are women. This research uses empirical evidence to examine the hypothesis that husbands are more willing than their wiv...

The conceptual framework applied here is based on the synthesis framework of fertility control developed by Easterlin and Crimmins. The data came from the 1974 Korean National Family Survey, which was conducted as part of the World Fertility Survey. The study focuses on the...
