Macon County Alabama Topological Faces with 2020 Census Geocodes

2023 data from the U.S. Census Bureau's MAF/TIGER Database provides topological polygon primitives for Macon County, Alabama. Each face includes unique identifiers and key geographic area codes used for tabulating 2020 Census and survey data. The shapefiles are designed to stand alone or be combined for national coverage.

Use Cases

• Dissolve face geometries on key geographic area codes like Census Tract Number or Block Group to build custom administrative boundaries.
• Analyze spatial relationships between different geographic hierarchies using attributes such as County Fips Code and Congressional District Code.
• Join face data with demographic datasets using the unique topological face identifier (TFID) for enriched geographic analysis.
• Extract and map specific area types like American Indian/Alaska Native/Native Hawaiian Areas or ZIP Code Tabulation Areas for regional studies.

Strengths
