This dataset contains 4 distinct basic statistics and condition concept counts. Select from the buttons below to access each version of the Basic Statistics and Condition Concept Counts.

For the SEER databases, each number in the database name references the number of registries included in the database (8 registries in SEER 8, 12 in SEER 12, etc.). Each database includes the registries from the smaller ones (e.g. SEER 12 includes all registries in SEER 8) with only the start dates that are different.

Description

The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics to inform efforts to reduce the cancer burden among the U.S. population. Supported by the Surveillance Research Program (SRP) in NCI's Division of Cancer Control and Population Sciences (DCCPS), SEER offers access to Research Data through a downloadable application called SEER*Stat. The information provided here reflects the Research Data available in SEER*Stat that includes registries with data from multiple years ranging from 1975 to 2021.

For more information on which registries are in each database see: Registry Groupings in SEER Data and Statistics - SEER Registries
