Volunteering is a form of civic participation that can improve individual, community and societal health. Additionally, civic participation can expand an individual's social network and increase their social capital, which may lead to more employment opportunities.
Data from multiple studies show an average 22% reduction in mortality among those who volunteer compared with those who do not. Volunteers have a lower risk of high blood pressure and are less likely to have obesity. Those who volunteer also experience mental health benefits, including reduced depression and increased life satisfaction and well-being. Volunteering may have particular benefits for older adults. There is emerging evidence that seniors who volunteer regularly have fewer cognitive complaints and a lower prevalence of mild to moderate dementia than seniors who do not volunteer regularly.
Americans continued to perform community service throughout the challenges of the COVID-19 pandemic. An estimated 60.7 million people in the United States formally volunteered between September 2020 and September 2021. Altogether, volunteers served 4.1 billion hours, worth approximately $123 billion in economic value.
Populations more likely to participate in organized volunteer work include:
The U.S. government has multiple programs to organize opportunities for potential volunteers, including AmeriCorps, Peace Corps, Citizen Corps and poll worker positions. Government opportunities are listed on Volunteer.gov. These programs have been shown to increase adult volunteering, even after exiting the program.
Schools, jobs or community organizations can also encourage or require volunteering. Volunteer requirements in high school increase the odds of adult volunteering. More corporations have begun offering employees paid time off to volunteer, which has the added benefit of improving employee retention and satisfaction.
Many nonprofit organizations rely on volunteers. Online advertising gives these organizations a powerful tool to find and encourage people to volunteer.
Healthy People 2030 identifies volunteering as a form of civic participation, one of the social determinants of health.

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.
