ZCTA-Level Summary of Residential Air Conditioning Prevalence

This dataset includes summary information on the prevalence of air conditioning (AC) across ZIP Code Tabulation Areas (ZCTAs) in the United States. While the spatial boundaries reflect ZCTAs and counties for the specified year (2010,2015,2020), the AC prevalence estimates are based on predictive models calibrated using data from 2021. This allows the dataset to represent 2021 AC conditions aligned with historical geographic definitions for comparative analysis.
