Union Mills skews older: half of its residents are older than 48.8, well above the national median of 40.1. That usually means more empty nesters and retirees, and fewer young families. The median age has climbed from 40.3 in 2006–10, but in a place this small, survey estimates can swing a lot from one release to the next.

About these numbers

Every figure on this page is a BestNeighborhood calculation from the Census Bureau's American Community Survey (ACS), built up from the Census block groups that make up Union Mills. Each ACS 5-year release pools five years of responses; this page shows the last 15 releases, 2006–10 through 2020–24. Neighboring releases share four of their five years, so they move gradually and small changes between them are within the survey's margin of error; in small places the lines can jump from one release to the next for the same reason. The maps show the same measures for each neighborhood, ranked against the whole country.
