Union is a place of small households, averaging 2.39 people against 2.65 for the U.S., which points to many singles, couples and roommates and relatively few children. That is in line with the rest of Iowa. Household size has dropped from 2.71 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. 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.
