Monroe County PA Topological Faces With Census Geocodes

U.S. Census Bureau provides topological face polygons for Monroe County, Pennsylvania, containing key geographic area codes for 2020 Census and annual surveys. These faces are the areal primitives that make up the seamless national MAF/TIGER System. The dataset enables the construction of various geographic area geometries by dissolving faces on their included codes.

Use Cases

• Construct Census tract geometries by dissolving face polygons on the Census Tract Number attribute.
• Analyze land use patterns by filtering faces using the Landwater Flag to separate land from water bodies.
• Map county subdivisions by aggregating faces based on the County Subdivision Fips Code.
• Create ZIP Code Tabulation Area (ZCTA) maps by dissolving faces on the 5 digit zip code tabulation area code.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER System, ensuring national consistency.
• Faces include key geographic area codes for both the 2020 Census and annual estimates, supporting multi-year analysis.
• Topological design ensures no overlaps or gaps between polygon features.

Limitations

• Specific row count, column count, and file size are unknown, making it difficult to assess the dataset's scale.
• Data is limited to a single county (Monroe, PA), requiring combination with other files for broader regional or national analysis.
