Each metric’s most recent reading, ranked against peers by value rather than by change. The MOD-IV assessment aggregates appear only here: they are a single published snapshot, and a change needs two observations.

Interpretation
written by Gemma 4 E4B · ollamaThe underlying figures have changed since this was written. Treat it as out of date until it is regenerated.
Union County has experienced significant appreciation across its housing metrics. Over the observed windows, the median owner-occupied home value increased by +33.1%, ranking it third among peer regions. Similarly, the median gross rent rose by +29.0%, placing the county second in this category. These strong increases are reflected in the Home value index, single-family, which saw a +28.7% change, though this metric ranks 20th of 21, suggesting it is at the worst end of the peer cohort.
Despite the rapid growth in housing costs, the median household income increased by +24.8%, and the annual rent to household income ratio rose by +3.1%, ranking the county third among peer regions. The unemployment rate also saw a notable decline of -33.8% over its window. However, the underlying supply metrics show contraction, with residential units permitted decreasing by -28.4%, ranking 16th of 21. Furthermore, the net migration rate declined sharply by -63.2%, ranking 17th of 21.
When interpreting these figures, it is important to note several caveats. The analysis relies on data from multiple sources, including the American Community Survey, where consecutive 5-year estimates overlap by four years, meaning short windows may understate the true separation. Additionally, the Zillow Observed rent index, while showing a +30.4% increase, rests on a thinner base and ranks against a smaller cohort than the home value figures. Finally, while the median household income increased by $24.8%, the median gross rent increased by $29.0%, indicating that housing costs are rising at a faster pace than household income.

Caveats
- ACS 5-year vintages overlap by four years, so consecutive estimates are not independent measurements and short windows understate the real separation.
- Affordability ratios are computed by this platform from two published series, not published by either source. The monthly value or rent series is averaged over the survey year to match the annual income denominator.
- Zillow's rent index begins in 2015 and covers far fewer places than its home-value index, so any rent figure rests on a thinner base — and ranks against a smaller cohort — than a value figure.
- HUD publishes income limits per county, so every AMI-based figure here is a county figure. HUD does not sanction allocating one down to a municipality.
