Life Expectancy Census Tract Data Visualization
Life Expectancy at Birth for U.S. States and Census Tracts, 2010-2015
This interactive United States map shows estimates of U.S. life expectancy at birth by state and census tract for the period 2010-2015 (1-2). Estimates were produced for 67,148 census tracts, covering all states and the District of Columbia (D.C.). These estimates are the result of the collaborative project, “U.S. Small-area Life Expectancy Estimates Project (USALEEP),” between the National Center for Health Statistics (NCHS), the National Association for Public Health Statistics and Information Systems (NAPHSIS), and the Robert Wood Johnson Foundation (RWJF) (2).

(The following data table describes the currently displayed map)
- Census tracts are sub-county geographic areas with an average population size of 4,000, ranging from 1,200 to 8,000 people. The mortality data used to produce the estimates by census tract are final death counts for each year of the 2010–2015 period, collected from death certificates, filed in state vital statistics offices and geocoded with census tract codes. The population data used include counts of the population residing in the United States enumerated as of April 1, 2010 by the decennial census conducted by the U.S. Census Bureau and population estimates based on the 2011-2015 5-year American Community Survey (ACS). Census tract codes may be identified based on an address using the FFIEC Geocoding/Mapping System available from: https://geomap.ffiec.gov/FFIECGeocMap/GeocodeMap1.aspxexternal icon.
- The methodology developed to produce the life expectancy estimates by U.S. census tract consists of a combination of standard demographic techniques and statistical modeling, which addressed the challenges posed by small population sizes and small and missing age-specific death counts (2). See reference (2) for a detailed description of the methodology used to produce the estimates.
- The methodology used to estimate the life tables for Maine and Wisconsin differs slightly from that used to estimate the life tables for all other registration areas, because they did not have all the years of mortality data required initially for this study. For details, see the addendum in U.S. small-area life expectancy estimates project: Methodology and results summary report (2).
- Estimates were not produced or published for census tracts with population of less than 5,000 over the 5-year period, 2011-2015, for Maine and Wisconsin and the 6-year period, 2010-2015, for all other registration areas; for census tracts with age-specific death counts greater than population counts; and, for census tracts with life expectancy at birth estimates with standard errors greater than 4 years.
- The 2010 Census cartographic boundary files shown on this map are simplified representations of census tracts from the U.S. Census Bureau’s MAF/TIGER geographic database and were chosen because it takes less time to render on screen. These boundary files are not to be used for geographic analysis including area or perimeter calculation, geocoding addresses, or determining precise geographic area relationships.
