The data is not encouraging — Arapahoe County scores just 10/100 on the Boom Town Index, ranking #892 of 996 counties. Job growth at -0.2% and median household income of $92,292 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 $480,500 against an income-to-home-value ratio of 0.19 means housing eats a bigger share of local earnings than the national norm. Renters face $1,708/month on average.
Population and employment in Arapahoe County are both close to flat — population +0.4% YoY and jobs -0.2%. Home values shifted -3.8% over the past 12 months. A steady-state county, neither expanding quickly nor shrinking.
In significant numbers — 5.78% 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.
