Life expectancy at birth provides an estimate of the number of years a person is expected to live. It is a good measure of the overall health of an area. Life expectancy is calculated using birth, death, and population data. The files available on this website provide life expectancy at birth for Missouri, its 115 counties (114 counties plus the City of St. Louis, which is an independent city), and Missouri’s seven Behavioral Risk Factor Surveillance System (BRFSS) Regions. Data are also available for Independence, Joplin, Kansas City, and Eastern Jackson County in the 2004-2012 file, the 2008-2016 file and the 2011-2019 file. Life expectancy is provided for the total population, for males, and for females. Life expectancy by white and black race is available for selected geographies that have large enough minority populations.
