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.
Below you will find an index of Chester County data listed by planning topic. You can also download an excel file of all data.
2020 Census Data Availability
On August 12, 2021, the Census Bureau released local level data from the 2020 census. Information on this data is detailed on the Census Bureau's website. On September 16, 2021, these data were formatted in a more user-friendly format and posted at data.census.gov. Planning commission staff is currently examining this data set to extract data that relates to Chester County. We have formatted some of this data (Total Population and Housing Units) and have made it available in an Excel spreadsheet. We will be adding additional data sets to this Excel file throughout October 2021.
The Census Bureau has 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. These maps are user-friendly, and can currently be used to access much of the census 2020 data which will be posted as a complete data set on September 30, 2021.
