    • Ports and Port Statistical Areas

    Metadata Updated: July 17, 2025

    The Ports and Port Statistical Areas dataset is periodically updated by the United States Army Corp of Engineers (USACE) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Per Engineering Regulation 1130-2-520, USACE’s NDC and WCSC are responsible for collecting, compiling, printing, and distributing all domestic waterborne commerce statistics for which the USACE has responsibility. Per a 1998 Office of Management and Budget (OMB) memorandum, the WCSC inherited the requirement to include foreign waterborne commerce formally executed by the U.S. Census Bureau. Performance of this work is in accordance with the Rivers and Harbors Appropriation Act of 1922 (33 USC 555).

    Engineering Regulation 1130-2-520 defines a port as:

    (1) Port limits defined by legislative enactments of state, county, or city governments.

    (2) The corporate limits of a municipality. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/2ngc-4984
