SEER Data & Software

The SEER research data include SEER incidence and population data associated by age, sex, race, year of diagnosis, and geographic areas (including SEER registry and county). SEER releases new research data every Spring based on the previous November’s submission of data.

Use SEER data to address multiple topics; for example, you can:

Examine stage at diagnosis by race/ethnicity.
Calculate survival by stage at diagnosis, age at diagnosis, and tumor grade or size.
Determine trends and incidence rates for various cancer sites over time.

SEER Incidence Database

Incidence and population data associated by age, sex, race, year of diagnosis, and geographic areas.

Documentation for SEER Data

Variable definitions and other documentation related to reporting and using SEER and related datasets.

U.S. Datasets

U.S. Mortality

The data include all causes of death, not just cancer deaths.

U.S. Populations

The county population estimates currently used in the SEER*Stat software.

Standard Populations

The age distributions used as weights to create age-adjusted statistics.

SEER Linked Databases

Each of these databases reflects the linkage of SEER data with one or more other large data sources.
