Carver County posts a median household income of $123,144. Martin County comes in at $62,969. That $60,175 gap separates the wealthiest and least wealthy counties in Minnesota and illustrates just how uneven the income map can be within a single state border.
The median household income across Minnesota's 87 counties is $71,573, above the national median of $63,162. But that single figure conceals deep local variation. Urban cores, college towns, and suburban job centers pull income figures upward, while rural and economically isolated counties drag them down.

Across Minnesota, the counties with the highest incomes also tend to post the highest rates of bachelor's degree attainment, reinforcing the connection between educational access and economic outcomes at the county level. Carver County has 50.5% of adults with a bachelor's degree or higher. Martin County has 23.8%. The education gap does not fully explain the income gap, but it maps closely onto it.
Income and poverty figures at the county level reflect decades of investment decisions, infrastructure gaps, and labor market shifts. Counties near major employment centers and with strong educational institutions consistently outperform their neighbors on income measures. Those further from economic hubs, or reliant on industries that have contracted, face structural headwinds that income support alone cannot reverse. Understanding the county-level picture is the starting point for targeting resources, whether for business investment, policy intervention, or community planning.
