Description: Feature Class was developed by the Prince George's County Health Department and the Office of Information Technology’s GIS Division to display the Healthy Food Priority Areas. These areas were developed by using the Census Tracts as its base and determining the Healthy Establishments and Unhealthy Establishments, based of the Food Facilities Inspection data from the Health Department, in each tract. This was then used to determine the Retail Food Environment Index (RFEI) for each tract. This dataset was adopted as part of the County Council of Prince George’s County’s Healthy Food Priority Areas, CR-99-2020, legislation. Population information was gathered from the U.S. Census Department's American Community Survey (ACS) 2014 - 2018 estimates data.

Description: The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.Block Groups (BGs) are clusters of blocks within the same census tract. Each census tract contains at least one BG, and BGs are uniquely numbered within census tracts. BGs have a valid code range of 0 through 9. BGs have the same first digit of their 4-digit census block number from the same decennial census. For example, tabulation blocks numbered 3001, 3002, 3003,.., 3999 within census tract 1210.02 are also within BG 3 within that census tract. BGs coded 0 are intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. Block groups generally contain between 600 and 3,000 people. A BG usually covers a contiguous area but never crosses county or census tract boundaries. They may, however, cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. </P>The BG boundaries in this release are those that were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.
