These data come from the U.S. Census Bureau's American Community Survey. They are based on averages of data collected in 2015, 2016, 2017, 2018, and 2019. 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.

We use 5-year estimates because they are available for all counties and allow comparison to other counties within the region.
