Intelligence and family size

This paper describes the results obtained in administering a modified Terman intelligence test to 327 Greek children aged from 7 to 12 years. A negative correlation between intelligence and family size was obtained. The results are compared with those obtained in similar inquiries in Britain and the U.S.A.     

Attitudes toward family size and family planning in nairobi

In Nairobi, 352 married African adults, 152 men and 200 women, were interviewed on their attitudes toward family size and family planning. The respondents had, on the average, slightly less than three children at the time of interview and hoped to add slightly more than three children to this total. There was little difference in desired family size by sex.About one-half of both men and women had some knowledge of family planning methods, and there was a general interest (75 percent of the men and 90 percent of the women) in learning more. In addition, two out of every three men, and nine out of every ten women, approved of family planning, and even greater majorities of both sexes were willing to have the government of Kenya provide such services.In spite of their approval, however, only 13 percent of the men, and 2 percent of the women, had ever practiced family planning. These findings are broadly comparable to those found in other emerging nations and suggest that knowledge, interest, and approval generally precede use.     

Postwar trends in family size

Recognizing that postwar trends in family size derive both from changes in the living arrangements of adults and from changes in the presence of children, this paper develops annual estimates of mean family size, mean members less than 18, and mean members 18 and older by race, by family type, and by age of head. Group differences in the course and source of changes in family size are evident as anticipated on the basis of group differences in family structure, economic resources and life cycle stage.     

The family size utility function

This article discusses the family size utility function (FSUF), which portrays the relative strengths of preferences among family sizes, as held by an individual, couple, or group. Derivable from the FSUF are indications of motivation to seek or avoid additional children, indications which may prove useful for understanding fertility decisions and for predicting completed fertility. A method is described for assessing the FSUF with data obtainable by interview surveys, and case studies of actual FSUF’s are presented. The article concludes with theoretical and empirical questions for further investigation of the FSUF.     

Desired family size and the efficacy of current family planning programmes

Abstract This paper takes a look at the belief that the number of couples currently desiring to limit family size is sufficiently large (and the intensity of their desire sufficiently strong) that the provision of supplies, services and education - the standard family planning package - will be adequate to bring the birth rate down to acceptable levels within a reasonable time period. Evidence comes from other countries, from attitude surveys and behavioural studies in India, from a priori considerations about what is reasonable to expect, and from certain demographic considerations. The most reasonable conclusion to draw from this evidence is that the belief is not correct. If the birth rate is to be brought down to target levels, additional methods - perhaps monetary incentives - seem to be necessary.     

Population and family planning of minority groups]

The population of minority groups has been increasing rapidly in recent years, but the rate of increase is different depending on the region, for various reasons: 1) Population increase rates are high in flat, low regions with warm weather, a good natural environment, and good transportation systems. Productivity is beginning to lag behind population growth (population increased by 90% from 1953 to 1982). 2) Population is increasing at a slower rate in high regions with cool weather and an average natural environment. The productivity growth rate in these regions is about the same (the population increased by 37.5% from 1949 to 1980). 3) Population is increasing at a lower, or even negative, rate in mountainous regions with little flat land and poor transportation service. 4) In some regions, large families are predominant because of tradition and/or religion. In some minority groups, where large extended families are the rule, increases are low because of health problems. People in minority groups are willing to practice family planning, but it is impossible to make one general family planning policy because people in different regions face different problems.     

Population growth with variable family size

"The Sharpe-Lotka continuous time deterministic model of population growth is developed to take account of some possible forms of mother-daughter fertility association....Model specific results relating the intergenerational fertility effect to the long term population growth rate and magnitude are established. The quantitative implications of the theory are illustrated by a consideration of a general bilinear form of A and in this context numerical results illustrating the finite time growth and also the long term distribution of fertility levels in the stable female population are obtained. In particular, it is shown that different fertility specific subpopulations can coexist indefinitely."     

Population growth with variable family size

The Sharpe‐Lotka continuous time deterministic model of population growth is developed to take account of some possible forms of mother‐daughter fertility association, characterised here by a bivariable measure, A. This leads to a linear double integral equation for which, subject to certain conditions, a finite time solution can be found by Laplace transform methods and thus also model specific results relating the intergenerational fertility effect to the long term population growth rate and magnitude are established. The quantitative implications of the theory are illustrated by a consideration of a general bilinear form of A and in this context numerical results illustrating the finite time growth and also the long term distribution of fertility levels in the stable female population are obtained. In particular, it is shown that different fertility specific subpopulations can coexist indefinitely.     

Family influences on family size preferences

Several studies have demonstrated important effects of parents’ childbearing behavior on their children’s childbearing preferences and behavior. The study described here advances our understanding of these family influences by expanding the theoretical model to include parental preferences, siblings’ behavior, and changes in children’s preferences through early adulthood. Using intergenerational panel data from mothers and their children, we test the effects of both mothers’ preferences for their own fertility and mothers’ preferences for their children’s fertility. Although both types of maternal preferences influence children’s childbearing preferences, mothers’ preferences for their children’s behavior have the stronger and more proximate effects. Mothers’ preferences continue to influence their children’s preferences through early adulthood; siblings’ fertility is an additional determinant of children’s family size preferences.

The measurement of family size preferences and subsequent fertility

A new method for measuring preferences for number of children is presented and related to the subsequent fertility of a panel of married women over a five-year period. TheI-scales, developed on the basis of unfolding theory, reflect the individual's utility function for children. They differ from global stated preferences and are more fine-grained measures, sensitive to variations from a first choice. Scales obtained at an initial interview were found to be consistently predictive of fertility in the prospective period, net of a number of other variables usually associated with differential fertility. Their potential both as independent and dependent variables in research is discussed.     

An analysis of the size of the family household and family structure in China]

Since 1949, great social and economic changes have taken place in China. The entire economic structure and social relations are no longer the way they used to be. These changes have also had a strong impact on the size of family households and family structure. Major changes are summarized as follows: (1) The size of the present family household has been greatly reduced from its earlier size. The main reason for this reduction in size is the change of the social system. Under the new social system, the natural population growth rate and family structure have shown the greatest change from the past. (2) The major change in family structure is that small families have replaced the traditional large families. Under the large family system, several generations may stay together as one household, and brothers do not divide the large family even after they are married. Under the small family system, a household is normally limited to the parents and their children. With the gradual disappearance of large families, small families are increasing rapidly. Some households with three generations living together are still in existence, and the young and the old may support each other in their daily life. Both in cities and in rural areas, the traditional custom of respecting one's old parents still exists. There must be a value and necessity for the existence of this particular kind of family structure.     

Minority status and family size: A comparison of explanations

Summary In this study, the family sizes of Chinese, Japanese and Filipino Americans are compared with those of whites, using data from the 1970 public use samples for California and Hawaii. The two hypotheses derived from the 'minority status' hypothesis are tested; the latter states that minorities experience tensions and anxiety which lead to lower fertility compared with native whites of Anglo-Saxon ancestry under certain conditions. We also examine the effect of assimilation in terms of variables known to affect fertility, and control for several age and acculturation variables. Analysis, based on a regression decomposition model, gives some support to the argument that the family size of minority groups differs from that of native whites because of incomplete assimilation and because independent variables affect fertility differently. However, since the independent effect of minority status per se is generally to raise fertility for Japanese and Chinese Americans, and lower it for Filipinos, we reject this version of the minority status hypothesis. Our general conclusion is that family size differentials in a pluralistic society may be part of a persisting pattern of sub-cultural differentiation, and do not necessarily reflect any 'tensions and anxiety' of minority status.

Economic determinants of family size in West Africa

The economic theory of fertility postulates that income and prices, broadly defined, are important determinants of family size. What follows is an attempt to test this theory against the behavior of 717 predominantly urban households in Sierra Leone. Husband's education is used as a proxy for income; the "price" of a child is accounted for by wife's education and wife's wage rate. Other important variables are wife's age, a measure of child "quality," wife's age at first birth, and child mortality. The findings of the study tend to lend support to the economic theory of fertility but contain certain peculiarities which indicate a need for further research.

The formation and stability of ideal family size among young people

A sample of 1,123 sixth, ninth, and twelfth graders in two Southern counties was questioned to ascertain how many children they think is ideal. More than three-fourths of the students in each grade had given thought to an ideal number of children for themselves; fewer had thought about the ideal number for the average American couple. Two and three children were the modal responses; mean ideal sizes were 3.02 for self and 3.16 for the average couple. The range of acceptable fertility behavior, “too few” or “too many” children, is defined by medians of 1.56 and 5.96. Ideal and acceptable family sizes increase slightly in the higher grades. A sex difference in ideals appeared only at grade 12; girls wanted more children. Negroes wanted fewer children than did whites at grade 6, more at grade 12. Size of family of orientation was directly related to ideals at grades 6 and 9, but the relation was curvilinear at grade 12. The direct relation between ideals and socioeconomic status became more pronounced at grade 12. Ideal sizes were larger for Catholics than for other religious groups. The study lends at least minimal support to the notion that early socialization affects ideas about family size.     

The differential attainment of family size goals by Race

Summary The 1973 U.S. National Survey of Family Growth is used to examine the effects of removing number and timing failures from the reproductive histories of various cohorts of white and black married women. Blacks are more fertile than whites primarily because of their greater unwanted fertility. Removing number and timing failures from the past reproductive histories of American women would have reduced their fertility considerably. These reductions would have been greater for blacks than for whites and would be greater if some wanted pregnancies had continued to terminate in foetal loss.
