The data is not encouraging — Arapahoe County scores just 3/100 on the Boom Town Index, ranking #966 of 1001 counties. Job growth at +0.3% and median household income of $101,087 reflect an economy that has been contracting or stagnating relative to the rest of the country.
Arapahoe County leans toward the expensive side. A median home value of $561,200 against an income-to-home-value ratio of 0.18 means housing eats a bigger share of local earnings than the national norm. Renters face $1,891/month on average.
Arapahoe County's population is growing — up +0.6% YoY — while the job market is roughly flat (employment change of +0.3%). Home values shifted -3.5% over the past year. In-migration is outpacing local hiring, which often points to remote workers or retirees driving the headcount.
In significant numbers — 5.52% of Arapahoe County's current population relocated from another state, well above the national norm. That level of in-migration usually signals a county where jobs, affordability, or quality of life are pulling people in from elsewhere.
