What makes Union different
Home Value, By Source
The Census Bureau's American Community Survey (2023 5-year estimate) puts Union's median home value — across all owner-occupied homes, not just recent sales — at $382,900. Separately, Boone County's current median listing price (via Realtor.com data, 2026-06-01) runs $428,000. These cover different geography (city vs. county) and different measures (assessed value vs. active listings), which is why we show both rather than picking one — full source list on our data sources page.
County Price Trend
Boone County's FHFA house price index shows a 3.23% annual change in 2025.
Population & Income
Union has an estimated population of 7,494 and a median household income of $139,013, per the Census Bureau's American Community Survey (2023 5-year estimate).
Affordability Snapshot
Union's Census-reported median home value works out to about 2.8x the area's median household income, and median gross rent runs roughly 15% of that same income on an annualized basis. Housing economists commonly flag a price-to-income ratio above 4x as historically elevated -- useful context, not a personal affordability verdict.
