Expected Survival Life Tables
Expected survival life tables are used when calculating relative survival statistics and crude probability of death using expected survival. Files containing expected survival tables for use in statistical software are available below. These contain the same data distributed with the SEER*Stat software.
The expected survival tables distributed by SEER contain the expected probabilities of surviving the interval conditional on being alive at the beginning of the interval, and represent life tables, generated from the general U.S. population data. The tables provided are for 1970-2007. The 1970-2000 tables are calculated using the U.S. Decennial Life Tables from the National Center for Health Statistics (NCHS), while the 2001-2007 numbers are from the NCHS annual U.S. life tables. Smoothing methods are used to generate annual tables between the census years before 2000. Different methods are used to calculate life tables for other races. See Documentation for the Expected Survival Life Tables for more information.
