U.S. Metropolitan Area County Classifications for FY 2009

Metropolitan Area Look-Up is a system from the U.S. Department of Housing and Urban Development that allows users to determine if a selected county is part of an OMB-defined Core Based Statistical Area. It provides a mapping of state and county combinations to their FY 2009 CBSA status.

Use Cases

• Identify which counties belong to a Core Based Statistical Area (CBSA) based on state and county selections.
• Analyze the geographic distribution of metropolitan areas using the OMB-defined CBSA classifications.
• Support demographic or economic research by linking county-level data to its FY 2009 metropolitan area status.

Strengths

• Data originates from the authoritative U.S. Department of Housing and Urban Development.
• Uses official Office of Management and Budget (OMB) area definitions published for FY 2009.
• System is designed for direct lookup of state and county combinations against CBSA criteria.

Limitations

• Data is static and based on definitions from Fiscal Year 2009, which may not reflect current metropolitan boundaries.
• The system is an HTML-based lookup tool, not a structured tabular dataset, limiting bulk analysis.
• No row count, column details, or sample data are available to assess the underlying data volume or structure.
