This article reviews some studies testing evolutionary theories of aging and shows that they are not always confirmed. Nevertheless, many gerontologists consider now that these theories provide a general explanation of the aging process. In such conditions, we may wonder whether time has come to...

In the present study, features of and trends in child-parent proximity in Sweden are analyzed using comprehensive register data. The results show that 85% of older parents have adult children within a radius of 50 km, of which 10% live ‘just around the corner’; corresponding figures...

In this study, we present a system of descriptions of family-demographic behavior in developed countries. We use life-table techniques in order to describe the experience of men, of women, and of children in processes related to family formation and family dissolution. We develop a large number...

We investigate whether declines in the age difference between spouses has influenced widowhood and nursing home demand. We first use life-table methods to simulate the impact of the declining age gap on the risk of widowhood. We then use the Medicare Current Beneficiary Survey and the Census...

The probability of divorce in the U.S. has remained constant for the last two decades at about 'half of all marriages.' While this estimate is well established, and marked differentials in divorced rates are well known, there are no reliable estimates of differences in the cumulative probability...

Deterministic population forecasts do not give an appropriate indication of forecast uncertainty. Forecasts should be probabilistic, rather than deterministic, so that their expected accuracy can be assessed. We review three main methods to compute probabilistic forecasts, namely time series...

In this paper, we analyze seasonality of deaths by age and cause in the U.S. using public use files for the years 1994 to 1998 by the methods of regression and a variation of Census Method II. We answer the following questions: For each age cohort, how much does each cause of death contribute to...

We investigate the determinants of geographical distances to parents. We focus on the role of family members who live outside the household (the parents themselves, and siblings), and on the distinction between the effects of life events and effects related to the timing with which these events...

Interdisciplinary studies that draw on long-term, global population projections often make limited use of projection results, due at least in part to the historically opaque nature of the projection process. We present a guide to such projections aimed at researchers and educators who would...

A sample covering 204,394 blocks from the 1990 U.S.Census permits measurement of residual heterogeneity from local area to local area after controlling by stratification for demographic characteristics such as race, ethnicity, age, sex as well as geographic characteristics such as region and...
