Metropolitan Planning Organization Boundaries in the United States

Federal Highway Administration data provides geographic boundaries for Metropolitan Planning Organizations (MPOs) across the United States. Compiled on November 10, 2025, this dataset supports multimodal transportation planning and programming. It includes planning locations, sizes, and names for metropolitan areas.

Use Cases

• Analyze the geographic size and distribution of MPO boundaries for national transportation infrastructure planning.
• Map MPO planning locations to assess regional coverage and identify potential gaps in transportation planning networks.
• Integrate MPO boundary data with other spatial datasets for multimodal transportation system analysis.

Strengths

• Sourced from the authoritative Federal Highway Administration and the U.S. Department of Transportation.
• Includes a documented data dictionary accessible via a DOI (10.21949/1529038) for attribute information.
• Part of the structured National Transportation Atlas Database (NTAD) framework.

Limitations

• No row or column count is provided, making the dataset's scale and feature complexity unknown.
• The sample data and specific file formats are unavailable, hindering preliminary assessment of data structure.
• The description lacks details on temporal coverage, limiting analysis of boundary changes over time.
