San Diego County Topological Face Polygons with 2022 Census Geocodes

2022 data from the U.S. Census Bureau's TIGER/Line system provides polygon topological primitives for San Diego County, CA. Each face includes unique identifiers and key geographic area codes for Census tabulation. The dataset is designed to stand alone or be combined with other shapefiles for national coverage.

Use Cases

• Dissolve face geometries on the County Fips Code to build county-level boundaries for spatial analysis.
• Analyze the distribution of Census Tract Number codes across topological faces to understand enumeration area composition.
• Join face attributes using the unique topological face identifier (TFID) to other Census data for demographic mapping.
• Extract Block Group information from face records to support granular population and housing studies.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database (MTDB).
• Each topological face includes key geographic area codes for 2020 Census and annual survey tabulation.
• Shapefiles are topologically integrated, representing a seamless national file with no overlaps or gaps.

Limitations

• Specific row count, column count, and dataset size are unknown, limiting assessment of scale.
• Data is a 2022 extract; more recent demographic changes within the county are not reflected.
• Geographic coverage is limited to San Diego County, CA, not suitable for broader regional analysis without combination.
