US Small-Area Life Expectancy Project is a joint effort of The Robert Wood Johnson Foundation, National Association for Public Health Statistics and Information Systems (NAPHSIS), and the National Center for Health Statistics (NCHS) to create life expectancy data at the census tract level. Life expectancy was calculated using address-level death records and estimates of population by age group in each census tract. The death records are exact, but the population figures are estimates based on a sample from the American Community Survey. Therefore, these life expectancies are estimates as well. In some tracts, the populations were too small to produce an estimate. Additionally, some age groups in some tracts had no deaths. Mortality rates for these age groups had to be interpolated, or estimated base on similar and nearby data. This is a six-year average, covering the period from 2010 to 2015.
