Data & Software for Researchers

About the SEER Data

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 research data are released every Spring based on the previous November’s submission of data.

Use SEER data to address multiple topics, for example:

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

Other Datasets

Several data sources are used in calculating and reporting cancer statistics. Additional datasets are available including: Standard Population Data, U.S. Mortality Data, and U.S. Population Data.
