Philadelphia County Topological Faces with Geocodes, 2023

U.S. Census Bureau provides a 2023 TIGER/Line shapefile of topological face polygons for Philadelphia County, PA. Each face includes unique identifiers and key geographic area codes for Census data tabulation. The data is part of a seamless national database with no overlaps or gaps.

Use Cases

• Dissolve face geometries on key geographic area codes like Census Tract Number or Block Group to build custom geographic area boundaries.
• Analyze spatial relationships by joining datasets using the unique topological face identifier (TFID) present in each polygon.
• Map demographic or survey data by linking attributes to geographic codes such as County Fips Code or 5 digit zip code tabulation area code contained in the face attributes.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File / TIGER Database (MTDB).
• The dataset is part of a seamless national file with no overlaps or gaps between geographic parts.
• Polygons contain key geographic area codes for all areas used in 2020 Census and annual surveys.

Limitations

• The dataset is limited to a single county (Philadelphia County, PA), not a national or regional extract.
• Specific data volume metrics like row count, column count, and file size are unknown from the input.
• The description does not specify the geometric precision or potential positional accuracy of the polygon boundaries.
