National Neighborhood Data Archive

The National Neighborhood Data Archive (NaNDA) is a publicly available data archive containing measures of the physical, economic, demographic, and social environment at multiple levels of spatial scale (eg, census tract, ZIP code tabulation area, county). Each NaNDA dataset covers all or most of the entire nation (including both rural and urban areas) and represents a set of measures on a single topic of interest, including socioeconomic disadvantage, healthcare, housing, partisanship, and public transit, with temporal coverage dating back to 1981.

国家社区数据档案库（NaNDA）是一个公开可用的数据档案库，其中包含多个空间尺度（例如，人口普查区、ZIP代码统计区域、县）的物理、经济、人口和社会环境指标。每个NaNDA数据集覆盖整个国家的大部分或全部地区（包括农村和城市地区），并代表一组关于单一感兴趣主题的指标，包括社会经济劣势、医疗保健、住房、政治立场和公共交通，时间跨度可追溯至1981年。
