The connection between education and health is well documented. Higher educational attainment is associated with higher earnings, increased health literacy and better self-reported health. Individuals with lower educational attainment are at a greater risk of adverse health outcomes such as cardiovascular disease and premature death. Increased time in school is also connected to higher civic engagement in adulthood.
The prevalence of high school graduation is higher among:
Keeping children and adolescents in school through high school graduation and beyond is key to increasing equitable health outcomes. Several programs have been successful in improving high school graduation rates by targeting high-risk populations. Strategies for increasing graduation rates — and ultimately, health equity — include:
The Institute of Education Sciences lists several recommendations for preventing dropout and improving graduation rates, including providing intensive, individualized support to students who have fallen off track and engaging students by offering curricula and programs that connect schoolwork with college and career success.
Interventions to increase high school graduation rates should target social, economic and health-related barriers to graduation. These include absenteeism, chronic illness, poverty, hunger, developmental delay due to chronic stress, homelessness and teen pregnancy. The expansion of school-based health centers can help address some of these barriers.
Increasing the proportion of students who graduate in four years with a regular diploma is a Healthy People 2030 adolescent health objective.

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.
