Welcome to the Planning Commission's Data Index web page, which was created to provide basic population, economic, and other data regarding Chester County. This web page includes tables, downloadable data spreadsheets, and links to other web sites that provide data on a wide range of topics.
The data on this website has been gathered from a number of national, state, and county agencies which publish data throughout the year. As a result, the data on this website is gathered and posted as it becomes available. US Census data is typically updated in the winter and early summer, while most county data is updated in mid spring. If you cannot find what you are looking for, try entering a key word in this search box.
In addition, the Planning Commission has produced a Chester County Economy report that provides a wide range of economic data. The Delaware Valley Regional Planning Commission has established a Municipal Data Navigator which can be used to access demographic and other data regarding municipalities and counties in southeastern Pennsylvania and the New Jersey suburbs of Philadelphia. It also lists data for the nine-county region as a whole.

The 2020 Decennial Census for Chester County
Every ten years the federal government conducts a "decennial" census in which each person in America is counted or "enumerated." On September 16, 2021, the U. S. Census Bureau released local level data from the 2020 Census, as detailed at the Census Bureau's website. The Census Bureau posted this data at data.census.gov.
Planning commission staff extracted the 2020 Census Data relating to Chester County's 73 municipalities and formatted it in an easy-to-use Excel format. These data provide municipal-level data addressing total population, age, housing units, population density, group quarters (such as nursing facilities and university dorms), race, and Hispanic or Latino populations. A downloadable file of all this data is available in an Excel spreadsheet.
The Census Bureau has also created a web page entitled Infographics and Visualizations which includes maps and charts illustrating the 2020 census results. One of these maps is the 2020 Census Demographic Data Map Viewer, which provides selected data about counties and census block groups nationwide. Another useful map provides 2020 State and County population and housing data.
