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.     

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.     

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.     

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.     

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.

Reference groups and family size norms

The concept of reference groups is introduced as a theoretically useful mechanism involved in diffusing collective norms and values about family size and in formation of family size ideals of individual family members. Data were gathered via self-administered questionnaires from a random sample of 140 urban and 55 rural families in the Lansing, Michigan metropolitan area. Findings show major variations by sex. Conformity to a two-child family norm in the family size ideals of wives depends on the extent to which they are exposed to this norm through reference group interaction and on the size of their families of origin. Husbands' family size ideals are influenced by size of family of origin but not by reference group interaction. In further exploring this pattern of findings, important differences emerge by controlling for educational attainment and residential location.Revised version of a paper presented at the Annual Meeting of the American Sociological Association, Session "Population: Fertility Behavior," Chicago, September 5–9, 1977.

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.     

Bargaining over family size: The determinants of fertility in Brazil

Understanding how households make fertility decisions is important to implementing effective policy to slow population growth. Most empirical studies of this decision are based on household models in which men and women are assumed to act as if they have the same preferences for the number of children. However, if men and women have different preferences regarding fertility and are more likely to assert their own preferences as their bargaining power in the household increases, policies to lower fertility rates may be more effectively targeted toward one spouse or the other. In this paper, we test the relevance of the single preferences model by investigating whether men and women's nonwage incomes have the same effects on the number of children in the household. We find that while increases in both the man and woman's nonwage income lower the number of children in the household, an equivalent increase in the woman's income has a significantly stronger effect than the man's. In addition, we find that increases in women's nonwage transfer income have the strongest effects on the fertility decisions of women with low levels of education. The most important policy implication of our results is that policies aimed at increasing the incomes of the least-educated women will be the most effective in lowering fertility rates.     

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.     

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.     

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 impact of children on household saving: Age effects versus family size

Summary This paper extends a recent article by Allen Kelley, 'Population Growth, the Dependency Rate, and the Pace of Economic Development', published in Population Studies, 27, 3. Its objectives are threefold: (1) to point out that Kelley's earlier assessment of the effect of family size on household savings rates turns on somewhat arbitrary methods of computation and is altered when more conventional procedures are used, (2) to argue that in modern American society the savings behaviour of families may be tied more to the ages of the children than to their number, and (3) to provide some comparative evidence which tends to substantiate Kelley's conjecture that the way and extent to which children influence household savings patterns depends upon the underlying level of economic development.

The utility of happiness

The issue. Nineteenth century utilitarian philosophers considered happiness as the highest good (utility in their words) and claimed political priority for attempts to promote the greatest happiness for the greatest number. In reaction, many of their contemporaries cried out that happiness is not good at all, because it turns people into contented cows and undermines social bonds. Modern psychologists, however, tend to suggest positive effects: sharper awareness, more activity, better social functioning and better health. Data. No empirical investigations have yet focussed on consequences of happiness. Nevertheless, indications can be found in various studies covering other matters. This paper gathers the available data. These data do not allow definite conclusions, but do suggest several small yet noteworthy effects. Enjoyment of life seems to broaden perception, to encourage active involvement and thereby to foster political participation. It facilitates social contacts: in particular contacts with spouse and children. Further, happiness buffers stress, thereby preserving health and lengthening life somewhat. There is no evidence of harmful effects. It is concluded that society is more likely to flourish with happy citizens than with unhappy ones.     

The interrelations of marital status,fertility, family size and intelligence test scores

In this paper data relating to men born in 1924 in the two southernmost counties of Sweden, and called up for military service in 1944 are analyzed. The population registers yield certain demographic and social information about these men, and this may be related to their performance in an intelligence test administered when they were called up. The association between test scores and level of schooling on one hand, and such variables as nuptiality, age at marriage, number of sibs, marital fertility, the incidence of pre-nuptial conceptions and occupational class is discussed, and an estimate of the influence of differential fertility on the trend of intelligence is given.     

Attitudes toward family size in some East European countries

Summary The paper is a review of published materials on attitudes toward family size derived from nationwide family planning studies conducted in Czechoslovakia, Hungary, Poland and the USSR around 1970. Priority is given to the findings on expected family size, though other attitudinal variables such as the ideal number of children and/or the number planned at marriage are also discussed. The paper shows that the majority of women in all the countries surveyed tend to have a limited number of children. Although the trend is especially striking among better-educated and gainfully employed women, it is also spreading fast, particularly among the younger generations, through the whole urban and rural population. The average expected family size is generally close to, and for a sizeable group of women below, replacement level. The trend toward a small family size is only partially a reflection of real desires. Various factors, most of them apparently of an economic nature, prompt many women to have fewer children than they would wish. If the average expected fertility were equal to that considered as ideal or to that planned at marriage there would be no danger that births would fall below replacement level. In contrast to the situation in the countries as a whole, women in the Asian Republics of the USSR not only expect but also tend to regard as ideal a family with larger numbers of children.
