A recent study by researchers at the University of Minnesota looks at state and national level variations in childrenâÄôs health coverage.

Although the insurance rates have been increasing, the study reveals gaps in coverage for certain groups of children based on age, race and income.

In Minnesota, 6.2 percent of children are uninsured, compared to 9.9 percent nationally. Children over the age of 12 are most likely to have no insurance.

Nationally, low-income children are 2.7 percent more likely to be uninsured than those from higher income families.  Lack of insurance is also higher with children of color. The variation is especially high in Minnesota where 22.5 percent of Hispanic children are uninsured.

âÄúMinnesota stands out in that regard,âÄù said Peter Graven, a graduate research assistant at the State Health Access Data Assistance Center. However, Graven said the report does not take on the issue or offer in depth explanation for the causes.

There are ongoing additional analyses on the issue to be posted at a later date with more detailed results.
