Miami-Dade County Topological Faces with Geocodes for 2023

2023 TIGER/Line shapefile from the U.S. Census Bureau provides topological face polygons for Miami-Dade County, Florida. Each face includes unique identifiers and key geographic area codes for Census data tabulation. The data is part of a seamless national database designed for independent use or combination.

Use Cases

• Dissolve face geometries on the TFID to reconstruct specific geographic area boundaries like Census tracts or block groups.
• Join face attributes, such as the key geographic area codes, to demographic data for spatial analysis within Miami-Dade County.
• Use the topological face primitives as a base layer for network analysis, ensuring no overlaps or gaps between adjacent polygons.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database.
• Topological structure ensures a seamless national file with no overlaps or gaps between polygons.
• Each face includes key geographic area codes for 2020 Census and annual survey data tabulation.

Limitations

• Dataset scope is limited to Miami-Dade County, Florida, requiring combination with other files for broader regional analysis.
• Unknown row count and specific column details limit precise assessment of data volume and feature completeness.
• Data is from 2023 and may not reflect recent boundary changes or demographic shifts.
