The document contains two reports on consequences of population trends for families and older adults in the United States. The reports were submitted as testimony before congressional committees on population and aging. The first report discusses projected changes in American family life in light of population growth, enrollment in schools and colleges, and labor force participation. Findings from analysis of population data indicate that changes in family life will be consistently smaller after 1970 than they were from 1950 to 1970. Major reasons for this slower rate of change include slackening in the birth rate, enrollment in schools and colleges, and labor force participation. The conclusion is that Americans will cope with pressures that affect nuclear family life by means of adjustments such as delays in marriage, decline in family size, and increasing diversity of living arrangements. The second report discusses projections of population, health, and mortality trends among persons 65 years old and older from 1976 to 2020. Prospective trends indicate that the proportion of elderly persons in the total population will rise more slowly than in the past, life expectancy at birth will remain around 73.5 years, moderate reductions in death rates for men and women will occur in the next several decades, and the health needs of the elderly will account for a larger share of the national budget.
