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

This dataset contains model-based place (incorporated and census designated places) 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 2019 Census TIGER/Line place boundary file in a GIS system to produce maps for 27 measures at the place 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.

本数据集包含基于模型的场所（包括和人口普查指定的地点）级别的估计值，适用于2020年PLACES项目的GIS友好格式发布。PLACES项目是对原始500城市项目的扩展，涵盖了整个美国——包括50个州和哥伦比亚特区（DC）——在县、地点、人口普查区和ZIP编码统计区域（ZCTA）等地理级别上。该项目代表了一种前所未有的尝试，旨在对这一大规模的本地区域进行信息统一发布，涉及4个地理级别。估计值由疾病控制与预防中心（Centers for Disease Control and Prevention，简称CDC）的人口健康部、流行病学和监测分支提供。该项目由罗伯特·伍德·约翰逊基金会（Robert Wood Johnson Foundation，简称RWJF）与CDC基金会联合资助。生成这些基于模型的估计值所使用的数据源包括行为风险因素监测系统（Behavioral Risk Factor Surveillance System，简称BRFSS）2018年或2017年的数据、人口普查局2010年的人口估计值以及美国社区调查（American Community Survey，简称ACS）2014-2018年或2013-2017年的估计值。2020年发布使用2018年BRFSS数据对23项指标进行估计，以及2017年BRFSS数据对4项指标（高血压、服用高血压药物、高胆固醇和胆固醇筛查）进行估计。由于相关问题在BRFSS中每两年才会询问一次，因此有四项指标基于2017年BRFSS数据。这些数据可以与2019年人口普查TIGER/Line地点边界文件结合使用，在GIS系统中生成27项指标的地点级别地图。同时，还提供了一个ArcGIS Online功能服务，用户可通过https://www.arcgis.com/home/item.html?id=8eca985039464f4d83467b8f6aeb1320在线制作地图或向桌面GIS软件添加数据。
