An updated resource from the Kaiser Family Foundation provides information on how insurance has changed and expanded under the ACA and provides data on insured and uninsured individuals. “The Uninsured and the ACA: A Primer” emphasizes the impact that health insurance can have on the uninsured and change health outcomes and financial impact. Lack of insurance affects people’s ability to access medical care and damages financial security. As a result, uninsured individuals are less likely to receive preventative care.
