Long-Range Trends In Adult Mortality: Models And Projection Methods, John Bongaarts
Long-Range Trends In Adult Mortality: Models And Projection Methods, John Bongaarts
Poverty, Gender, and Youth
This Population Council working paper has two objectives: (1) to test a new version of the logistic model for the pattern of change over time in age-specific adult mortality rates, and (2) to develop a new method for projecting future trends in adult mortality. A test of the goodness-of-fit of the logistic model for the force of mortality indicates that its slope parameter is nearly constant over time. This finding suggests a variant of the model that is called the shifting logistic model. A new projection method based on the shifting mortality model is proposed and compared with the widely …

Trends And Transitions In Children's Coresidence With Older Adults In Beijing Municipality, Zachary Zimmer, Xianghua Fang, Toshiko Kaneda, Zhe Tang, Julia Kwong
Poverty, Gender, and Youth
The reduction in family size in China and concurrent social and economic change are raising concerns that traditional sources of support may be eroding. This Population Council working paper paper examines a) whether rates of coresidence between older adults and their adult children in the Beijing municipality of China have been declining, and b) the determinants of coresidence and coresidence transitions. Results suggest that family support structures for the elderly, when they are facilitated through coresidence, remain basically intact, particularly for those who require the greatest amount of support. Further assessment is required to elucidate the effects of availability, need, …
Population Aging And The Rising Cost Of Public Pensions [Arabic], John Bongaarts
Population Aging And The Rising Cost Of Public Pensions [Arabic], John Bongaarts
Poverty, Gender, and Youth
Rapid population aging is raising concerns about the sustainability of public pension systems in high-income countries. The first part of this study identifies the four factors that determine trends in public pension expenditures: population aging, pension benefit levels, the mean age at retirement, and the labor force participation rate. The second part presents projections to 2050 of the impact of demographic trends on public pension expenditures in the absence of changes in pension benefits, labor force participation, and age at retirement. These projections demonstrate that current trends are unsustainable, because without reforms population aging will produce an unprecedented and harmful …
Gender Differences In Time Use Among Adolescents In Developing Countries: Implications Of Rising School Enrollment Rates, Amanda Ritchie, Cynthia B. Lloyd, Monica J. Grant
Gender Differences In Time Use Among Adolescents In Developing Countries: Implications Of Rising School Enrollment Rates, Amanda Ritchie, Cynthia B. Lloyd, Monica J. Grant
Poverty, Gender, and Youth
Researchers at the Population Council have been involved in the collection of data on time use from adolescents in India, Kenya, Pakistan, and South Africa. Three questions are addressed in this working paper: (1) How does time use change during the transition to adulthood? (2) Does gender role differentiation intensify during the transition? (3) Does school attendance attenuate gender differences? The data document differences in time use patterns between students and nonstudents. Although female adolescent students still work longer hours than male adolescent students, the gender division of labor that typically develops during adolescence is greatly attenuated among students when …
Popular Perceptions Of Emerging Influences On Mortality And Longevity In Bangladesh And West Bengal, Sajeda Amin, Alaka Malwade Basu
Popular Perceptions Of Emerging Influences On Mortality And Longevity In Bangladesh And West Bengal, Sajeda Amin, Alaka Malwade Basu
Poverty, Gender, and Youth
Although new environmental and pathological threats to human survival and longevity have been documented, relatively little is known about how these threats are perceived in the popular imagination. During fieldwork in rural Bangladesh and West Bengal, India, researching the changing costs of and motivations for reproduction, the authors included survey questions on respondents’ perceptions of changing mortality. Child-mortality levels were perceived to have fallen drastically in recent times, but for the middle-aged and the elderly, the past was seen as a better time in terms of health and survival. The decline in adult health is attributed to environmental deterioration and …
