With health insurance open enrollment season on the horizon, we here at QuoteWizard wanted to see which states have made the biggest improvements in reducing uninsured rates. Since the inception of the Affordable Care Act (ACA) in 2010, there have been major improvements to the uninsured rate. From 2010 to 2019 there was a 37% decrease in uninsured Americans, totalling 17.5 million people nationally. The good news is all 50 states saw some level of improvement to their uninsured rates. However, not all states experienced significant increases as some did.
The driving force behind the drop in uninsured rates is likely the expansion of Medicaid under the Affordable Care Act. ACA laws increased eligibility for adults with incomes below 138% of the federal poverty level to be covered under Medicaid. While the ACA increased eligibility for Medicaid, many states have not adopted Medicaid expansion. Currently there are 39 states that have adopted some form of Medicaid expansion. It’s those states who have adopted Medicaid expansion that saw the greatest decrease in uninsured people from 2010 to 2019. Among the top 25 states to decrease their rate of uninsured from 2010 to 2019, all 25 states have adopted Medicaid expansion. As the ACA faces a legal battle in the Supreme Court the insurance status of millions hangs in the balance of a court decision. If the ACA were to be repealed an estimated 21 million people could be left uninsured and over 12 million people could lose Medicaid coverage.
To rank states with the largest decrease in uninsured people, we analyzed Kaiser Family Foundation data on health insurance coverage of adults from 2010 to 2019. States are ranked from 1 being the greatest decrease of uninsured to 50 being the lowest decrease of uninsured. We also included the rate of Medicaid increases over the same time period to reflect how the expansion of Medicaid impacts uninsured rates.

States ranked 1 to 50, with 1 being the greatest improvement in uninsured rates and 50 being the lowest rate of improvement. We paired Medicaid increases from 2008 versus 2017 to show a correlation between states that participated in Medicaid expansion and those that saw a greater improvement in uninsured rates.
