Bars show percentile rank among all 996 counties.
The data is not encouraging — Contra Costa County scores just 4/100 on the Boom Town Index, ranking #946 of 996 counties. Job growth at +1.1% and median household income of $120,020 reflect an economy that has been contracting or stagnating relative to the rest of the country.
Contra Costa County leans toward the expensive side. A median home value of $787,300 against an income-to-home-value ratio of 0.15 means housing eats a bigger share of local earnings than the national norm. Renters face $2,234/month on average.
Employers in Contra Costa County are hiring — job growth of +1.1% — but the population is close to flat (+0.1% YoY). Home values moved -4.3% over the past year. Labor demand is outpacing local population growth, which tends to tighten wages and housing.
There's a moderate stream of newcomers. About 3.85% of residents moved from another state, which is above average and suggests Contra Costa County has appeal as a relocation destination — though it's not among the highest-inflow counties nationally.
