The results of recent evaluations of genome wide association (GWA) studies of complex phenotypic traits, including age at disease onset or life span, showed that such traits are typically affected by a large number of "small-effect-low-significance" alleles, which were excluded from further analy
Douglas Almond's use of the 1918 U.S. influenza pandemic as a natural experiment led to the seminal works on the subject of in utero health's impact on later life outcomes.
Aging is an evolutionarily labile trait that is likely shaped by a diversity of sources of natural selection.
There are indications that the mean difference in socioeconomic status between homeowners and renters has been increasing in recent decades, and that these trends vary by race and ethnicity.
The share of the homeless population composed of African Americans and children has grown since the early 1980s, but the causes of these changes remain poorly understood.
The prevailing model of migration in transitioning countries conceives of a risk-diversifying household in which members share a coherent set of preferences about the departure of one or more members to work elsewhere.
The Global Health Initiative (GHI), President's Emergency Plan for AIDS Relief (PEPFAR), the President's Malaria Initiative (PMI) and other global health programs are putting increasing emphasis on evaluation and learning to ensure that investments in global health are effective and achieve desir
Most demographic research on intergenerational processes focuses on the associations between the numbers and characteristics of individuals in successive generations, and ignores multigenerational (Non-Markovian) aspects of intergenerational mobility.
There is now consensus that concurrent partnerships increase transmission of infectious diseases in sparse networks -- like HIV in sexual partnership networks.
This paper reports on an extension of group-based trajectory modeling to address non-random subject attrition or truncation due to death that varies across trajectory groups. The effects of the model extension are explored in both simulated and real data.
