These are differences between published figures, not a forecast of your budget. Income and sales taxes, commuting, schools, insurance and the job you would actually get are not in them, and a price index describes a metropolitan area, so two places in one metro read the same. HUD’s rent is a benchmark for a new lease, not a listing.

A bolded value is the more favorable of the two where the metric has a clear direction. Metrics like population and density have no inherent better or worse and are shown unweighted.
The number of units permitted is not marked because the larger place always permits more; the per-resident rate is the fair comparison. The year-over-year change is not marked either: a percentage on fewer than 300 units swings on a handful of permits.
