Massachusetts County Subdivision Boundaries for 2025 Census

2025 boundaries for county subdivisions in Massachusetts, as reported through the Census Bureau's Boundary and Annexation Survey and Participant Statistical Areas Program. This shapefile extract from the MAF/TIGER System provides geographic and cartographic information for legally-recognized minor civil divisions and statistical census county divisions.

Use Cases

• Analyze Polygon boundaries for Minor Civil Divisions (MCDs) and Census County Divisions (CCDs) for spatial planning.
• Map Town and Township administrative areas for demographic or resource allocation studies.
• Identify Unorganized Territory (UT) and Barrio subdivisions for statewide geographic coverage analysis.

Strengths

• Boundaries reflect legal status as of January 1, 2025, ensuring current administrative data.
• Data is part of a seamless national TIGER/Line file system with no overlaps or gaps.
• Covers the entire area of Massachusetts through a combination of MCDs, CCDs, and unorganized territories.

Limitations

• Sample data and specific row/column counts are unavailable, limiting pre-analysis assessment.
• The dataset is a single-state extract; national analysis requires combining multiple standalone files.
