Benton County Oregon Topological Face Polygons with 2022 Census Geocodes

Benton County, Oregon topological face polygons from the 2022 TIGER/Line database contain key geographic area codes for all Census tabulation areas. The dataset provides the areal primitives used to build geometries for counties, tracts, and other geographic entities by the U.S. Census Bureau. Each polygon face has a unique topological identifier and associated geocodes.

Use Cases

• Dissolve face geometries on the County Fips Code to reconstruct the boundary of Benton County, Oregon.
• Aggregate face-level data using the Census Tract Number to analyze demographic statistics at the tract level.
• Build custom geographic areas by selecting and merging faces based on their 5 digit zip code tabulation area code.
• Validate the topological consistency of the MTDB by checking for overlaps or gaps between faces using their unique TFID.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database (MTDB), ensuring national consistency.
• Faces include key geographic area codes for all 2020 Census and annual survey tabulation areas, enabling multi-scale analysis.
• The MTDB is designed as a seamless national file with no overlaps or gaps between parts, providing topological integrity.

Limitations

• The dataset is a single county extract; national analysis requires downloading and combining hundreds of separate county files.
• Data is from 2022 and may not reflect recent boundary changes or annexations after that date.
• The shapefile format requires GIS software for visualization and spatial analysis, limiting accessibility for non-specialists.
