Marion County: Median age by Hispanic origin

These data come from the U.S. Census Bureau's American Community Survey. They are based on averages of data collected in 2011, 2012, 2013, 2014, and 2015. These estimates cannot be used to say what is going on in any particular year in the period, only what the average value is over the full period. The Census Bureau's American Factfinder provides 3-year estimates for counties with at 20,000 people, and 1-year estimates for counties with at least 65,000 people. We use 5-year estimates because they are available for all counties and allow comparison to other counties within the region.
Median age is the age at which half the population is younger and half is older.  A lower median age indicates a relatively younger population, while a higher median age indicates a relatively older population.  Median age varies by ethnicity.
The median age in 2011-2015 in Marion County...
  • was NA years for the total population;
  • was NA years for the Hispanic population.

NOTE: These ACS data are estimates based on a five-year average, meaning that data gathered from 2011, 2012, 2013, 2014, and 2015 are averaged together to come up with the results shown here. There is no problem with comparing these data to census data from 2000. For a technical discussion of the "margins of error" associated with ACS estimates, please see: (
