Population Dynamics Branch (PDB)

Demographic graphOverview/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 based on race, ethnicity, sex/gender, and age), 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 and policy experiments using methods addressing selection and other sources of bias. Research at multiple levels of analysis, involving interdisciplinary perspectives, incorporating social determinants of health, and elucidating mechanisms leading to health disparities are encouraged.


Decoding Maternal Morbidity Data Challenge (on Challenge.gov). NICHD invites innovative approaches to analyzing the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) dataset for up to $400,000 in prizes. Winning submissions will identify new research avenues on adverse outcomes, such as hypertensive disorders, diabetes, and infection, and address disparities in these outcomes. Solutions can use computational analysis, data mining, artificial intelligence, and other methods to advance research in maternal health. Submissions are due by 10/15/21.
