Jefferson County ranks #102 out of 1001 U.S. counties on the Boom Town Index with a score of 90/100, putting it in the top tier nationally. Job growth of +0.6% and a median household income of $66,301 point to a county with active economic momentum.
By national standards, Jefferson County is quite affordable. Homes here have a median value of $188,200, and the income-to-home-value ratio of 0.35 is well above the U.S. average — especially with median rent at just $1,213/month. Residents can generally buy a home without being cost-burdened.
Jefferson County is losing population (-0.9% YoY) while the job market is essentially flat (+0.6% employment change). Home values are +3.4% over the past 12 months. A slow-bleed pattern — not a collapse, but residents are leaving faster than employers are hiring.
There's a moderate stream of newcomers. About 3.31% of residents moved from another state, which is above average and suggests Jefferson County has appeal as a relocation destination — though it's not among the highest-inflow counties nationally.
