U.S. Zip Code to Congressional District Mapping for the 113th Congress

New Jersey's data.nj.gov provides a mapping of zip codes to their associated U.S. Congressional districts. The dataset covers the 113th session of Congress. It was last updated on March 24, 2023.

Use Cases

• Mapping voter registration or demographic data from 'Zip Code' to 'Congressional District' for constituency-level analysis.
• Validating address-based inputs by checking consistency between provided 'Zip Code' and expected 'Congressional District'.
• Aggregating economic or public health statistics by 'Congressional District' using 'Zip Code' as a join key.
• Analyzing historical representation by using the 'Congressional District' assignments for the fixed 113th Congress period.

Strengths

• Data is explicitly defined for the 113th Congressional session, providing a clear temporal scope.
• Offers multiple machine-readable formats including CSV, JSON, XML, and RDF.

Limitations

• The dataset is temporally stale, representing districts from the 113th Congress (2013-2015), not current districts.
• Unknown row count and sample size prevent assessment of completeness for all U.S. zip codes.
• Lacks metadata on source methodology or update process for the mappings.
