About PRB :
The Population Reference Bureau (PRB) is a private, nonprofit organization which informs people around the world about population, health and the environment for research or academic purposes and it was founded in 1929.
- PRB was founded by Guy Burch in 1929. In the early 1930s, it shared office space with the Population Association of America in New York City.
PRB aims to have a three-fold mission:
- Inform(inform people about up-to-date research on population-related issues),
- Empower(help people put the information to use), and
- Advance(make sure that policies related to population, health, and the environment are based on sound research).
The organization focuses its work around these “core themes”: Reproductive Health and Fertility; Children and Families; Global Health; Population and the Environment; Aging; Inequality and Poverty; Migration and Urbanization; and Gender. PRB also emphasizes two Strategic Approaches: Building Coalitions and Mobilizing Civil Society.
- PRB’s annual World Population Data Sheet is a double-sided wall chart that presents data from 200 countries on important demographic and health variables such as total population, fertility rates, infant mortality rates, HIV/AIDS prevalence, and contraceptive use.
- PRB’s online Data Finder allows users to search a database of hundreds of demographic, health, economic, and environment variables for countries, world regions, and states in the United States.
- PRB’s glossary of population-related terms has been described as an authoritative source by people writing about population
