Population Dynamics Branch (PDB)

Demographic graph

Overview/Mission

PDB supports research, data collection, and research training in demography, reproductive health, and population health.

In demography, the branch supports research on the scientific study of human populations, including fertility, pregnancy outcomes, mortality and morbidity (especially maternal, infant, child, adolescent, and young adult mortality and morbidity), migration, population distribution, population stratification (including disparities), nuptiality, family demography, population growth and decline, and the causes and consequences of demographic change.

In reproductive health, the branch supports behavioral and social science research on family planning, infertility, and sexually transmitted infections including HIV/AIDS.

In population health, the branch supports research on how demographic, social, economic, institutional, geographic, and other factors influence human health, productivity, behavior, and development, with an emphasis on research using population-representative data and natural experiments. Research at multiple levels of analysis, involving interdisciplinary perspectives, incorporating social determinants of health, and elucidating mechanisms leading to health disparities are encouraged.
