The Pennsylvania State Data Center has produced the official state and county detailed population projections for the Commonwealth of Pennsylvania for the past 30 years. The latest set of projections developed in 2012 forecast the population growth between 2010 and 2040. Data is available for Pennsylvania and its 67 counties. Projections were developed by five year age cohorts and gender.
The projections contain a wealth of data, information and analysis useful for planning, policy evaluation, the consideration of alternative public or private intervention activities, and the formulation and management of programs developed to deal with particular situations.
