McLennan County Topological Face Polygons with 2022 Census Geocodes

McLennan County, Texas, contains polygon data for topological faces, which are areal primitives from the Census Bureau's MAF/TIGER Database. Each face includes a unique identifier (TFID) and key geographic area codes for 2020 Census and survey tabulations. The dataset is part of the 2022 TIGER/Line series and can be combined with other county files for national coverage.

Use Cases

• Dissolve face geometries on key geographic area codes like Census Tract Number or Block Group to reconstruct official Census geographic boundaries.
• Analyze the topological relationships between faces using the unique TFID to understand adjacency and containment within the county.
• Join attribute data from other sources to faces using the County Fips Code or 5-digit ZIP Code Tabulation Area code for spatial analysis.
• Build a seamless national map by merging this county's topological face shapefile with others from the 2022 TIGER/Line series.

Strengths

• Data originates from the U.S. Census Bureau's authoritative Master Address File/TIGER Database, ensuring national consistency.
• Each topological face includes key geographic area codes for multiple Census tabulation levels, enabling multi-scale analysis.
• The dataset is part of the 2022 TIGER/Line series, providing a contemporary snapshot of geographic boundaries.

Limitations

• The specific number of rows (polygons) and columns (attributes) is not provided, making it difficult to assess the dataset's scale and granularity.
• As a single county extract, analysis of broader regional patterns requires downloading and merging multiple county files.
• The dataset's utility is limited to geographic and tabulation code attributes; it lacks demographic or socioeconomic data fields.
