PM2.5 Exposure, Social Vulnerability, and Chronic Disease Prevalence: Merged Census Tract-Level Dataset for 498 U.S. Cities, 2016–2022

Census tract-level analytical dataset compiled for examining environmental justice disparities in PM2.5 exposure and chronic disease prevalence across 498 U.S. cities. Integrates annual PM2.5 concentration estimates from the Atmospheric Composition Analysis Group (Washington University in St. Louis), Social Vulnerability Index (SVI) scores and thematic components from the CDC/ATSDR, and chronic disease prevalence estimates (asthma, diabetes, COPD, coronary heart disease, and cancer) from the CDC PLACES dataset. Compiled for the period 2016–2022 at the census tract-year level本数据集为普查分区（census tract）级分析数据集，旨在考察全美498座城市内PM2.5暴露与慢性病患病率的环境正义差异。该数据集整合了多源数据：来自圣路易斯华盛顿大学大气成分分析小组的年度PM2.5浓度估算值、美国疾病控制与预防中心/有毒物质和疾病登记署（CDC/ATSDR）发布的社会脆弱性指数（Social Vulnerability Index, SVI）评分及主题分量表，以及美国疾控中心PLACES数据集提供的五类慢性病患病率估算数据，涵盖哮喘、糖尿病、慢性阻塞性肺疾病（COPD）、冠心病与癌症。本数据集覆盖2016至2022年，数据粒度为普查分区-年度级别。
