SEER Registries

Geographic areas were selected for inclusion in the SEER Program based on their ability to operate and maintain a high quality population-based cancer reporting system and for their epidemiologically significant population subgroups. The population covered by SEER is comparable to the general US population with regard to measures of poverty and education. The SEER population tends to be somewhat more urban and has a higher proportion of foreign-born persons than the general US population.

Use the links on this page to view a description of each SEER registry, including the number of persons by race. The number of persons by race for all registries combined are presented in a separate table. Different combinations of the SEER registries are often used for specific analyses. The most common combinations are defined in SEER Registries - Common Terms.
