The SEER 9, 13, 18, and 21 delay research databases do not include individual registry identifiers. However, the databases that contain individual registry identifiers are released as specialized databases because cautions are necessary in using estimates for small populations which may be unstable or biased. A data use agreement is necessary for the user to acknowledge that he or she has read and understood the cautions involved in using these databases.

For the background and methodology, see Cancer Incidence Rates Adjusted for Reporting Delay.

The databases are available in the rate sessions in SEER*Stat for the November 2018 data submission.

How to Access the Delay Databases

In order to access the custom database, you must already have access to SEER research data through SEER*Stat in client-server mode.
