Residents under 18 outnumber those 65 and over, at 20.7 percent against 19.8 percent, a household formation profile rather than a retirement one.

- Cumulative net domestic migration, 2021 to 20244,268
- Rank by growth among US county-equivalents1140th of 3,144
The county has grown 2.12 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.

- Employment at those establishments180,733

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 $319,650 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 4.0 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 Plymouth County
Do SBA loans in Plymouth County get paid back?
- Loans with a final outcome recorded225
- Paid in full217
- Charged off8
- Charge-off rate on resolved loans3.6 percent
- Status: Paid in full217
- Status: Exempt from disclosure478
- Status: Cancelled79
- Status: Charged off8
- Status: Committed, not yet disbursed53
Of the 225 loans that have reached a final outcome, 3.6 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.

Plymouth accounts for 136 approvals against 96 in Brockton. County level figures average over that gap, which is why a site decision is made at the submarket rather than the county.
