County Typology Codes

An area's economic and social characteristics have significant effects on its development and need for various types of public programs. To provide policy-relevant information about diverse county conditions to policymakers, public officials, and researchers, ERS has developed a set of county-level typology codes that captures differences in economic and social characteristics.

The 2004 County Typology codes classify all U.S. counties according to six non-overlapping categories of economic dependence and seven overlapping categories of policy-relevant themes. The economic types include farming, mining, manufacturing, services, Federal/State government, and unspecialized counties. The policy types include housing stress, low education, low employment, persistent poverty, population loss, nonmetro recreation, and retirement destination. In addition, a code identifying counties with persistent child poverty is available.

An update of the County Typology codes is planned for 2014.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog. Data for this record includes the following resources: Download page For complete information, please visit https://data.gov.

某一地区的经济和社会特征对其发展及其对各类公共项目需求具有显著影响。为向政策制定者、公职人员和研究人员提供关于不同县区状况的政策相关性信息，经济研究服务局（ERS）开发了一套县级行政区类型代码，用以捕捉经济和社会特征之间的差异。
2004年县级行政区类型代码将所有美国县区按照六种非重叠的经济依赖类别和七种重叠的政策相关性主题类别进行分类。经济类型包括农业、矿业、制造业、服务业、联邦/州政府以及未特化的县。政策类型包括住房压力、低教育水平、低就业率、持续贫困、人口流失、非都市休闲和退休目的地。此外，还提供识别持续存在儿童贫困县的代码。
计划于2014年对县级行政区类型代码进行更新。本记录来源于美国农业部企业数据目录，该目录输入至https://data.gov目录。本记录的数据资源包括以下内容：下载页面。欲获取完整信息，请访问https://data.gov。
