PLACES: ZCTA Data (GIS Friendly Format), 2020 release

This dataset contains model-based ZIP Code tabulation Areas (ZCTA) level estimates for the PLACES project 2020 release in GIS-friendly format. The PLACES project is the expansion of the original 500 Cities project and covers the entire United States—50 states and the District of Columbia (DC)—at county, place, census tract, and ZIP Code tabulation Areas (ZCTA) levels. It represents a first-of-its kind effort to release information uniformly on this large scale for local areas at 4 geographic levels. Estimates were provided by the Centers for Disease Control and Prevention (CDC), Division of Population Health, Epidemiology and Surveillance Branch. The project was funded by the Robert Wood Johnson Foundation (RWJF) in conjunction with the CDC Foundation. Data sources used to generate these model-based estimates include Behavioral Risk Factor Surveillance System (BRFSS) 2018 or 2017 data, Census Bureau 2010 population estimates, and American Community Survey (ACS) 2014-2018 or 2013-2017 estimates. The 2020 release uses 2018 BRFSS data for 23 measures and 2017 BRFSS data for 4 measures (high blood pressure, taking high blood pressure medication, high cholesterol, and cholesterol screening). Four measures are based on the 2017 BRFSS data because the relevant questions are only asked every other year in the BRFSS. These data can be joined with the census 2010 ZCTA boundary file in a GIS system to produce maps for 27 measures at the ZCTA level. An ArcGIS Online feature service is also available at https://www.arcgis.com/home/item.html?id=8eca985039464f4d83467b8f6aeb1320 for users to make maps online or to add data to desktop GIS software.

本数据集收录了基于模型构建的ZIP代码统计区域（ZCTA）级别的估计数据，适用于GIS格式。PLACES项目是对原始的500 Cities项目的扩展，涵盖了整个美国——包括50个州及哥伦比亚特区（DC）——在县、地方、人口普查区和ZIP代码统计区域（ZCTA）等多个地理级别。该项目首次尝试以统一的方式，在如此大规模上对地方区域进行四维地理水平的全面信息发布。估计数据由疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）的人口健康部、流行病学与监测分支提供。项目资金由罗伯特·伍德·约翰逊基金会（Robert Wood Johnson Foundation, RWJF）与疾病控制与预防中心基金会共同资助。生成这些基于模型估计数据的数据来源包括2018年或2017年的行为风险因素监测系统（Behavioral Risk Factor Surveillance System, BRFSS）数据、2010年人口普查局的人口估计数据以及2014-2018年或2013-2017年的美国社区调查（American Community Survey, ACS）估计数据。2020年发布的版本中，23项指标使用了2018年的BRFSS数据，4项指标（高血压、高血压药物使用、高胆固醇和胆固醇筛查）使用了2017年的BRFSS数据，这是因为相关的问题在BRFSS中每两年才会被询问一次。这些数据可以与2010年人口普查的ZCTA边界文件在GIS系统中进行合并，以生成27项指标在ZCTA级别的地图。同时，用户也可以通过ArcGIS Online的在线功能服务（https://www.arcgis.com/home/item.html?id=8eca985039464f4d83467b8f6aeb1320）在线制作地图或添加数据到桌面GIS软件中。
