As the official source of population and economic statistics for the commonwealth, the Pennsylvania State Data Center has worked closely with the U.S. Census Bureau Population Division in development of the Population Estimates. The PaSDC provides input files as well as review of the population estimates prior to release.
Population estimates are available for the state and its counties by age, gender and race/ethnicity by 5 year age cohort. Municipal population estimates are also available.
The PaSDC also produces single year of age estimates (ages 0-19) by gender and race. These estimates are used in developing various health rates for the Pa Department of Health.
