SEER Registry Groupings for Analyses

The following combinations of the SEER registries are commonly used in various statistical analyses. For the numbers and percentage of individuals in each database grouping, see Number of Persons by Race and Hispanic Ethnicity for SEER Participants.

SEER 9 Registries

The SEER 9 registries are Atlanta, Connecticut, Detroit, Hawaii, Iowa, New Mexico, San Francisco-Oakland, Seattle-Puget Sound, and Utah. Data are available for cases diagnosed from 1973 and later for these registries with the exception of Seattle-Puget Sound and Atlanta. The Seattle-Puget Sound and Atlanta registries joined the SEER program in 1974 and 1975, respectively.

SEER 11 Registries

The SEER 11 registries consist of the SEER 9, as described above, plus Los Angeles and San Jose-Monterey. Los Angeles and San Jose-Monterey joined the SEER program in 1992. Therefore, data for the SEER 11 are available from 1992 on.

SEER 13 Registries

The SEER 13 registries consist of the SEER 11, as described above, plus Rural Georgia and the Alaska Native Tumor Registry. Data are available from all cases diagnosed from 1992 and later for these registries. These registries report on expanded race.

SEER 17 Registries

The SEER 17 registries consist of the SEER 13, as described above, plus Greater California, Kentucky, Louisiana, and New Jersey. Data are available from all cases diagnosed from 2000 and later for these registries. Louisiana cases diagnosed from July - December 2005 are excluded from most statistical analyses: all Louisiana cases are excluded from prevalence analyses. See Adjustments for Areas Impacted by Hurricanes Katrina and Rita for more information.

SEER 18 Registries

The SEER 18 registries consist of the SEER 17, as described above, plus Greater Georgia. Data are available from all cases diagnosed from 2000 and later for these registries, with the exception of adjustments for the areas impacted by Hurricanes Katrina and Rita.

Statistics for Diagnosis Years 1973-2011

Statistics that do not require population data to calculate (e.g., frequencies and survival) are often reported for years prior to 2000 for the SEER 18 and SEER 17 areas, and prior to 1992 for the SEER 13 areas. For these statistics, the SEER 9 registries contribute cases diagnosed from 1973 through 2011, except for Seattle-Puget Sound and Atlanta, which contribute cases beginning with 1974 and 1975, respectively. Los Angeles, San Jose-Monterey, Rural Georgia and the Alaska Native Tumor Registry contribute cases from the period 1992-2011; and Greater California, Kentucky, Louisiana, New Jersey, and Greater Georgia contribute cases from 2000-2011, with the exception of the July - December 2005 Louisiana cases.
