The county has grown 2.92 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.

These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. 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 $401,782 sits well above the median of $100,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 9.1 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

SBA loan default and charge-off rates in Miami County
Do SBA loans in Miami County get paid back?
- Loans with a final outcome recorded52
- Paid in full50
- Charged off2
- Charge-off rate on resolved loans3.8 percent
- Status: Paid in full50
- Status: Exempt from disclosure120
- Status: Cancelled20
- Status: Charged off2
- Status: Committed, not yet disbursed7
Of the 52 loans that have reached a final outcome, 3.8 percent were charged off. This is computed only over resolved loans, because a loan still running has not yet succeeded or failed and counting it either way would be wrong.
Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.

The county's own community in the status book, unincorporated Miami County (community 390398), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Miami County in radon zone 1, a predicted average indoor radon screening level greater than 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 78.6 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.
