Documentation of SEER*Stat Variables

  • Dictionary of  SEER Variables: Excel (XLSX, 39 KB) or PDF (PDF, 300 KB) - Updated October 2024
    Lists all the variables in the SEER*Stat databases with the following information: NAACCR item number, description and definitions, category name, and availability in the Research, Research Plus, and SEER 22 Limited-Field databases (see SEER Data Change History for more information).
  • Data Description for SEER Research and Research Plus (PDF, 889 KB) - Updated October 2024
    Provides documentation for each of the variables in the Research and Research Plus databases.

County attribute data from the U.S. Census are also linked to the SEER*Stat databases. Variables available are dependent on the type of database:

  • Research databases have two time-dependent fields available: Median Household Income and Rural-Urban Continuum Codes.
  • Research Plus databases have many fields available from the two types of county attributes: Static and Time-Dependent.
