Census Tract-Level Summary of Air Conditioning Prevalence

This dataset contains modeled estimates of air conditioning (AC) prevalence across U.S. census tracts using tract boundary definitions for the year 2010, 2015, and 2020. While the spatial boundaries reflect census tract and counties for the specified year, 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.
