Core Based Statistical Areas (CBSA)

Core Based Statistical Areas (CBSAs) provides the geographic boundaries and point information for more than 930 statistical regions defined by the U.S. Office of Management and Budget (OMB). A CBSA represents a highly populated core area and adjacent communities that have a high degree of economic and social integration with the core.

CBSAs consist of counties and county equivalents, and are defined in two categories:

Metropolitan Statistical Areas
Micropolitan Statistical Areas

The Core Based Statistical Areas (CBSAs) product uses County Boundaries as building blocks for CBSAs. Minor Civil Divisions (MCDs) are used to provide correspondence to New England City and Town Areas (NETCAs).

Combined Statistical Areas (CSAs) are built from Core Based Statistical Area (CBSA) boundaries using information provided in OMB Bulletins.

This sample data set covers the state of California. This represents a subset of the full product’s geographic extent. The full commercial offering features geographic coverage of the entire United States. Contact [e-mail] for more information on licensing the product.

基于核心区的统计区域（Core Based Statistical Areas）由美国行政管理和预算局（Office of Management and Budget，OMB）定义，涵盖超过930个由其划定的统计区域的地理边界与点位信息。单个CBSA代表人口稠密的核心区域，以及与该核心区域存在高度经济与社会融合度的邻近社区。

CBSA由县及相当于县的行政区域构成，分为两大类别：大都市统计区（Metropolitan Statistical Areas）与微型都市统计区（Micropolitan Statistical Areas）。

本基于核心区的统计区域数据集以县界作为构建CBSA的基础单元；民政分区（Minor Civil Divisions，简称MCDs）则用于匹配新英格兰城镇区域（New England City and Town Areas，简称NETCAs）的对应关系。

联合统计区域（Combined Statistical Areas，简称CSAs）依据OMB发布的公告信息，以CBSA的边界为基础单元构建而成。

本示例数据集覆盖加利福尼亚州，仅为完整产品地理覆盖范围的子集。完整的商用版本可覆盖美国全境。如需获取该产品的授权详情，请联系邮箱[e-mail]。
