Topological Faces Polygons for New York County with 2023 Geocodes

Topological face polygons from the U.S. Census Bureau's TIGER/Line database for New York County, NY, updated for 2023. This shapefile contains the areal primitives used to build all Census geographic areas, each with a unique topological face identifier (TFID). The data includes key geographic area codes for 2020 Census and annual survey tabulations.

Use Cases

• Dissolve face geometries on key geographic area codes like County Fips Code or Census Tract Number to reconstruct official Census boundaries.
• Join face attributes using the unique topological face identifier (TFID) to other Census datasets for demographic or economic analysis.
• Analyze the spatial relationship of faces containing codes for Congressional District Code and Block Group to study political or statistical geography.
• Use the face polygons with their embedded 5 digit zip code tabulation area code for cross-referencing postal and administrative boundaries.

Strengths

• Data is derived from the Census Bureau's Master Address File/TIGER Database, a seamless national file with no overlaps or gaps.
• Each face includes key geographic area codes for all areas tabulated in the 2020 Census and annual surveys, enabling multi-scale analysis.
• The dataset is part of the 2023 TIGER/Line series, providing current geographic boundaries and codes.

Limitations

• The dataset is specific to New York County, NY, limiting analysis to a single geographic area without combining other county files.
• As a topological extract, it requires GIS expertise and software for effective manipulation and analysis.
• Sample data and specific row/column counts are unavailable, making initial assessment of data volume and structure difficult.
