February 2022 update: Several specialized databases were updated for the November 2020 submission of the SEER data. Most databases now include an option to request the data with or without census tract-level SES and rurality fields.

In order to access a specialized database, you must already have access to the latest SEER Research Plus data with a valid Institutional Account.
