TIGER/Line Shapefile, 2017, nation, U.S., Current Combined Statistical Area (CSA) National

Published by U.S. Department of Commerce, U.S. Census Bureau, Geography Division, Spatial Data Collection and Products Branch | U.S. Census Bureau, Department of Commerce | Catalog Last Checked: April 12, 2026 at 11:52 PM | Dataset Last Updated: January 01, 2017 at 12:00 AM
The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Combined Statistical Areas (CSAs) are defined by the Office of Management and Budget (OMB) and consist of two or more adjacent Core Based Statistical Areas (CBSAs) that have significant employment interchanges. The CBSAs that combine to create a CSA retain separate identities within the larger CSA. Because CSAs represent groupings of CBSAs, they should not be ranked or compared with individual CBSAs. Boundaries are those defined by OMB based on the 2010 Census, published in 2013, and updated in 2015.
