According to confluence theory, a child is helped or hindered in intellectual development according to the average absolute intelligence (mental age) in the family when the child is born.

The "baby boomette," occurring since 1973, differs from the earlier "baby boom" in that the maximum number of births, the rate of growth, and the size of the yearly increase will all be less. Also, the rate of decline will be slower and the length of the boomette will be shorter. (MLF)

Describes a computer simulation providing population change profiles at 5-year intervals for 100 years, projecting natural rate of increase and total population, per capita gross national product, energy consumption, age-specific fertility rates, and survival ratios. Data sources for the simulation, sample printed output, and learning activities…

Discusses fertility of Hispanic adolescents in the United States. Summarizes what is known about sexuality, contraception, pregnancy, and childbearing among male and female Hispanics of various countries of origin.

Studied the timing of family formation in four Asian countries: Taiwan, Korea, Thailand, and Malaysia (N=14,849), and the operation of sociostructural variables in these societies. Results indicated that education and rural-urban origins have the same effect on the timing of family formation in each of these countries. (LLL)
