Residents 65 and over outnumber those under 18, at 24.2 percent against 19.5 percent, which points demand at health care, services and single story product rather than schools.

The county has grown 5.96 percent since the 2020 census base. Deaths exceeded births in 2024 and the population still grew, so all of the growth came from people moving in. A market held up by migration is more sensitive to a change in relative cost than one growing from household formation.

County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The average approval of $576,564 sits well above the median of $240,850, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 27.3 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

The county's own community in the status book, unincorporated Mason County (community 530115), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Mason County in radon zone 3, a predicted average indoor radon screening level less than 2 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
