The expected survival life tables are provided by individual year 1970-2015, individual age 0-99 years, and race (White, Black, Other (American Indian/Alaska Native, Asian/Pacific Islander), All races for Other unspecified 1991+ and Unknown). The maximum age for the life tables is 99 (changed from 118 in the 1970-2007 life tables) because there is evidence that life tables for older ages are unstable. For more on the maximum age, see Expected Survival Life Tables.
1970-2000 Expected Survival
Expected survival for the years 1970-2000 come from the U.S. Decennial Life Tables from the National Center for Health Statistics (NCHS) for 1970, 1980, 1990, and 2000.
- Values for individual years are interpolated from the decennial tables (years 1971-1979 from the 1970 and 1980 life tables, 1981-1989 from the 1980 and 1990 life tables, and 1991-1999 from the 1990 and 2000 tables).
- NCHS provides tables for white, black, and all races combined (used for other unspecified 1991+ and unknown). We generated the 1970, 1980, 1990 and 2000 tables for the "Other (American Indian/Alaska Native, Asian/Pacific Islander)" race using standard methods for life table calculations with some modifications to incorporate information on live births and 0 year olds mortality counts broken down into <1 Day, 1-6 Days, 7-27 Days, and 28-364 Days.
2001-2017 Expected Survival
Expected survival for the years 2001-2017 come from the U.S. Annual Life Tables from NCHS.
- NCHS provides tables for white, black, and all races combined (used for other unspecified race 1990+ and unknown race). We generated the tables for the "Other (American Indian/Alaska Native, Asian/Pacific Islander)" races category. Mortality rates for 2000-2017 with 3-year overlapping groups for each year (e.g., 2015-2017 for 2016) were used to generate the expected survival for Other races for 2001-2016. The 2016 table was copied to 2017.
- The 2009-2015 other race life tables were updated using revised intercensal population estimates.
1970-2007 Expected Survival and Extended Age
An older set of tables are also available for 1970-2007 with ages 0-118. The decennial tables have data through age 109. The annual life tables have data through age 99. We extended the life tables through age 118 using the following calculation:
hazard rate(age) = hazard rate(age-1) * factor, where factor = 1.05 for males and 1.06 for females.
