- Rank by growth among US county-equivalents2860th
The county has lost 3.74 percent of its population since the 2020 census base. Deaths exceeded births in 2024, so all of the growth came from people moving in. A market held up by migration alone is more sensitive to a change in relative cost than one growing from household formation.

The average approval of $1,057,500 sits well above the median of $450,000, so a small number of large deals is pulling the mean up. The median is the better guide to what a typical borrower here actually gets. Only 12.5 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.
