Life Expectancy: The age an individual in a certain area is expected to live, based on local mortality rates and other demographic factors
National Center for Health Statistics (using 2011-15 American Community Survey estimates and 2010-15 National Vital Statistics System mortality data)
*Note: Each year of available data shown above is a 5-year estimate, or an average of data collected over a five year period. 5-year estimates are used to increase the reliability of the data at small geographies like neighborhoods and census tracts. The years shown on the NDSC map represent the final year of the five year average (e.g. “2010” represents 2006-2010 data, “2011” represents 2007-2011 data, and so on). For the most impactful comparison of data over time, the ACS recommends comparing non-overlapping years (e.g. 2010-14 with 2015-19).
