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.
2 rows above show both figures with a ± margin and neither in bold. Those come from the American Community Survey, which samples rather than counts, and the gap between the two is smaller than the uncertainty on the figures themselves — so the survey did not find a difference to report, and calling either one the winner would be reading a result out of noise.
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.
