Adjacent counties for the Hurricane Insurance Program - Wind Index (HIP-WI) are determined in accordance with the definition contained within the HIP-WI Endorsement.
Adjacent county - Counties identified in the US Census County Adjacency File located at www2.census.gov/geo/docs/reference/county_adj acency.txt or successor location, unless modified in the actuarial documents.
The above link has been succeeded, and the successor location is available at the US Census website address below:

For the 2024 crop year only, to transition from application of the previous county adjacency file to the most current county adjacency file, in all states except Connecticut where the HIP-WI Endorsement is available, both county adjacency files will be applied. For Connecticut, due to a substantive reorganization of county boundaries, the most current county adjacency file will be used. For the 2025 crop year, the updated adjacency file located in the endorsement will be used to determine county adjacency. DISPOSAL DATE: December 31, 2024
