Health insurance is critical for ensuring that children receive the medical care they need to achieve and maintain good health. Children with health insurance coverage are more likely to have a usual source of care and less likely to delay or forgo necessary medical care because of cost.
When compared with children who have health insurance, uninsured children experience more health disadvantages, including:
In 2023, 5.8% of children ages 0-19 in the United States had no health insurance, 61.2% were privately insured and 36.2% had coverage through public plans such as Medicaid, the Children’s Health Insurance Program (CHIP) or other government-sponsored health plans. The number of uninsured children in the U.S. rose by 4 million between 2022 and 2023.
The uninsured rate is higher among:
Public programs such as Medicaid and CHIP have made significant strides in increasing access to and the quality of care and improving health status for low-income children. States that have expanded Medicaid eligibility have substantially improved children's insurance rates. To date, 10 states have still not expanded Medicaid coverage.
The Centers for Disease Control and Prevention suggests several steps schools can take to help students with health care access, including identifying uninsured children at the beginning of the school year, educating families on their coverage options and offering enrollment assistance.
Increasing the proportion of Americans with health insurance is a leading health indicator for Healthy People 2030. The U.S. Department of Health and Human Services has a strategic goal to improve the availability and accessibility of health insurance coverage by increasing enrollment of eligible children in CHIP and Medicaid.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
