Young adults, those ages 18 to 24, was the group most likely to be uninsured. Since 2000, over 25% were uninsured, and the percentage of young adults without health coverage continued to grow throughout the next decade. New surveys now find that young adults have made gains in insurance coverage since 2010. The Obama Administration and officials from the Department of Health and Human Services attribute the gains made in reducing the number of uninsured in the young adult group to a provision of the Affordable Care Act that was implemented in September 2010. The provision allows dependents under the age of 26 to remain on their parents' health insurance policies.
