Details
Data are from FEMA's OpenFEMA API. See https://www.fema.gov/openfema-data-page/disaster-declarations-summaries-v2. Statewide declarations are expanded to all counties in the state.
Connecticut's pre-2022 counties (FIPS 09001-09015) are crosswalked onto the 2022-vintage planning regions (09110-09190) using a binary any-overlap assumption: a planning region is treated as having received a declaration if ANY overlapping pre-2022 county received it, even if only part of that county's area falls within the region. This is not a proportional/population-weighted allocation (unlike the crosswalks this package uses for dollar-valued FEMA datasets), since a declaration is a binary event, not a divisible amount.
