Education, Health & Community


In 2023, 28.50% of adults (25+) have a bachelor's degree or higher, which is markedly below the state rate (38.80%). High school or higher is 96.80%, which is far higher than the national rate (89.40%). The uninsured rate is 2.80%, which is far lower than the national rate (8.60%). The share of people in poverty is 7.40%, which is on par with the state rate (5.50%), up 5.90 percentage points since 2011 and above its 2019 pre-pandemic level by 4.50 percentage points. This signals a sharp increase in hardship - a shrinking consumer base, heavy pressure on public services, and job-market contraction risks. Among residents ages 3+, the largest enrollment group is elementary (46.70%). College enrollment is 7.52%, which is far lower than the national rate (26.70%), indicating the community may be more oriented toward vocational/trade or direct-to-workforce opportunities.
