New Estimates of Mortality Trajectories at Extreme Old Ages

A growing number of persons living beyond age 85 underscore the need for accurate measurement and modeling of mortality at advanced ages. This is also very important issue for making correct forecasts of population aging and related demands for medical services and social support. Earlier studies indicate that exponential growth of mortality with age (Gompertz law) is followed by a period of mortality deceleration with slower rate of growth. This study challenges earlier conclusions with new data and estimates. In this study we used U.S.

Foreclosure Rates, Neighborhood Disorder, and Health

Little is known about the health effects of the economic downturn, with foreclosure one of its most visible signs. Research in economics suggests that the impact of an economic downturn is first felt through emotional well-being. Hence we explore onset of depression over the interval of the economic downturn with a unique data source, the National Social Life Health and Aging Project (NSHAP). Fortuitously NSHAP wave 1 was collected in 2005-2006 and wave 2 in 2010-2011, bounding the economic downturn and foreclosure crisis.

The Paradoxical Origins and Radical Consequences of America's War on Immigrants

In a very real way, the rise of undocumented migration and the growth of America's undocumented population are a product of poorly conceived immigration and border policies, which in the course of a few decades transformed Mexico-U.S. migration from a stable, circular flow of male Mexican workers going to three states into a much larger settled population of Mexican families living in 50 states.

Credit Constraints and the Racial Gap in Post-Secondary Education in South Africa

This paper analyzes the impact of baseline household income and scholastic ability on post-secondary enrollment in South Africa. Using longitudinal data from the Cape Area Panel Study (CAPS), we analyze the large racial gaps in the proportion of high school graduates who enroll in post-secondary education. Our results indicate that baseline income and ability (measured in CAPS¿ literacy and numeracy evaluation) are strong predictors of post-secondary enrollment and statistically account for all of the black-white difference in enrollment.

Exploring the Construct of Allostatic Load within a Social/Psychological Model of Health

This presentation will focus on a program of research that seeks to identify and better understand the multiple biological pathways through which social factors impact on trajectories of aging. Major social factors of interest include the broad impact of socio-economic status as well as the influence of patterns of social interaction with others (including both the positive and negative features of such interactions and their respective impacts on physiology).

Population Change and Economic Inequality: Theory and Evidence on Two Proximate Influences

Past macro-level research linking population and economic development has emphasized national averages. Studies in this vein focus on national fertility rates and age structure (on the population side) and average per capita incomes or national school enrollments for instance (on the economic side). As a complement to this literature, our research draws attention to population influences on economic differentiation, both within and between countries.

Social Networks & Health: The Power of Connectivity

Dr. Valente will discuss the field of social network analysis and introduce several key hypotheses that show how networks influence behavior. He will present data from individual and community level studies on adolescent smoking, substance use, community coalitions, physician behavior, and transnational policy change among others. He will also present a taxonomy of network-based interventions and explore the utility of using social network data for accelerating the diffusion of innovations.

Lasting Welfare Effects of Widowhood in a Poor Country

Little is known about the situation facing widows andtheir dependent children in West Africa especially afterthe widow remarries. Women in Malian society arevulnerable to the loss of husbands especially in ruralareas. Households headed by widows have significantlylower living standards on average than male or otherfemale headed households in both rural and urbanareas; this holds both unconditionally and conditionalon observable household and individual characteristics including age.
