Denver County Topological Face Polygons With 2023 Census Geocodes

A 2023 extract from the U.S. Census Bureau's MAF/TIGER Database, providing topological face polygons for Denver County, Colorado. Each polygon includes key geographic area codes for all Census tabulation areas, enabling the reconstruction of geographic boundaries.

Use Cases

• Dissolve face geometries on the County Fips Code to create a precise county boundary map for Denver County.
• Build geometries for Census Tracts or Block Groups by dissolving face polygons on the Census Tract Number and Block Group attributes.
• Analyze spatial relationships between different geographic areas like Congressional District Code and 5 digit zip code tabulation area code using the shared topological face primitives.
• Join demographic data from other Census sources using the unique topological face identifier (TFID) present in each polygon.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER Database, ensuring national topological consistency.
• Polygons contain geocodes for all 2020 Census and annual survey tabulation areas, supporting multi-level geographic analysis.
• The dataset is part of the 2023 TIGER/Line series, providing recent geographic boundaries.

Limitations

• The specific row count and file size are unknown, making it difficult to assess the dataset's scale before download.
• As a single county extract, national or regional analysis requires combining many separate TIGER/Line files.
• The shapefile format may require GIS software for full utilization, limiting accessibility for some users.
