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.

本数据集基于2010、2015与2020年的普查区（census tract）边界定义，生成了美国全境各普查区域的空调（air conditioning）普及率模型估算值。尽管该数据集的空间边界采用对应年份的普查区与县界，但其空调普及率估算值均基于以2021年数据校准的预测模型所生成。此举使得本数据集能够匹配历史地理定义来呈现2021年的空调使用状况，便于开展对比分析。
