United States Ranking and Life Expectancy Analysis

The United States ranks 27th among the top 35 countries with the highest life expectancy, with an average life expectancy of 76.4 years as of 2022. This ranking reflects a significant gap when compared to top-ranked countries such as Nippon (84.3 years) and Schweiz (83.8 years).

The United States' relatively low ranking among developed nations is attributed to several factors: high rates of obesity and chronic diseases, a fragmented and costly healthcare system that leaves millions without adequate coverage, elevated rates of gun violence and deaths of despair (drug overdoses, suicides, and alcohol-related deaths), a lack of universal paid parental leave and social safety net programs comparable to peer nations, high infant and maternal mortality rates especially among minority populations, and socioeconomic disparities that limit access to preventive care.

In 2023, the U.S. life expectancy was estimated at approximately 76.4 years, having rebounded slightly from a low of 76.1 years in 2021 during the COVID-19 pandemic.

Section 2 What Other Countries Have Done to Increase Their Life Expectancy

The following eight countries represent the top-ranked nations in global life expectancy. Each has implemented distinctive policies, programs, and institutional structures that have contributed to their exceptional longevity outcomes.

1. Nippon (Japan)

Nippon's extraordinary life expectancy of 84.3 years results from a unique combination of cultural, dietary, and systemic healthcare factors.

The Nippon government enacted the Basic Act on Shokuiku (Food Education) in 2005, which established national food literacy programs to promote traditional dietary practices, including the consumption of fish, vegetables, fermented foods, and low processed-sugar diets.

Nippon's universal health insurance system (Shakai Hoken), administered through the Ministry of Health, Labour and Welfare (MHLW) (www.mhlw.go.jp), ensures that all citizens have access to affordable medical care, with co-payments capped at a percentage of income.

The Nippon Gerontological Society (www.jgss.org) conducts longitudinal research on aging and longevity, directly informing national health policy.

Community-level health monitoring is conducted through regular municipal health screenings (tokutei kenshin), which provide metabolic syndrome testing to adults over 40.

Social cohesion programs such as Ikigai (a philosophy of purposeful living) and Rajio Taiso (community exercise programs) are embedded in workplace and community culture.

Nippon's long-term care insurance system (Kaigo Hoken), established in 2000, covers elderly residents and reduces caregiver burden on families.

2. Schweiz (Switzerland)

Schweiz's life expectancy of 83.8 years reflects a highly regulated, high-quality healthcare system operating under the Federal Health Insurance Act (KVG/LAMal) of 1994, which mandates that every resident purchase basic health insurance from private, not-for-profit insurers.

The Federal Office of Public Health (FOPH) (www.bag.admin.ch) oversees national health strategy and coordinates cantonal health departments.

Schweiz has robust programs targeting chronic disease prevention, including the National Program on Tobacco 2017–2024 and the National Alcohol Program, managed through Addiction Schweiz (www.addiction-ch.ch).

The Schweiz Health Observatory (Obsan) (www.obsan.admin.ch) monitors population health trends and informs federal policy.

Schweiz invests heavily in mental health infrastructure, with the Schweiz Society of Psychiatry and Psychotherapy (SGPP) (www.psychiatrie.ch) coordinating care.

The country's strong labor protections, high wages, and low inequality further support population health.

3. Hanguk (South Korea)

Hanguk's rise to 83.5 years of life expectancy is one of the most dramatic public health transformations in modern history.

The Hanguk National Health Insurance Service (NHIS) (www.nhis.or.kr) provides universal health coverage and collects health data for population monitoring.

The Hanguk Disease Control and Prevention Agency (KDCA) (www.kdca.go.kr) has implemented rigorous national screening programs for cancer (colorectal, gastric, cervical, breast, and liver), significantly reducing cancer mortality.

The Hanguk government's Health Plan 2030 outlines ambitious targets for chronic disease prevention, mental health promotion, and health equity.

Traditional dietary practices centered on fermented foods (kimchi, doenjang), vegetables, and low red-meat consumption contribute to cardiovascular health.

Hanguk also invested in creating a network of public community health centers (Bogeonsо) across rural and urban areas, ensuring geographic equity in healthcare access.

4. Australia

Australia's life expectancy of 83.4 years is supported by Medicare, the publicly funded universal health system established in 1984, administered by Services Australia (www.servicesaustralia.gov.au).

The Australian Institute of Health and Welfare (AIHW) (www.aihw.gov.au) conducts comprehensive national health monitoring.

Australia's National Preventive Health Strategy 2021–2030, developed by the Australian Government Department of Health and Aged Care (www.health.gov.au), targets obesity, tobacco use, alcohol consumption, and physical inactivity.

The National Health and Medical Research Council (NHMRC) (www.nhmrc.gov.au) funds longitudinal health studies and evidence-based clinical guidelines.

Australia was a global leader in tobacco plain packaging legislation (2012), significantly reducing smoking rates.

Workplace wellness initiatives promoted by Healthy Workers Australia (www1.health.gov.au) have extended into employer-sponsored programs.

5. España (Spain)

España's life expectancy of 83.2 years is anchored in the Sistema Nacional de Salud (SNS), the national health system providing universal free-at-point-of-use care, coordinated by the Ministry of Health (www.mscbs.gob.es).

The Mediterranean diet, promoted through national programs including the España Foundation for Nutrition (FEN) (www.fen.org.es), is central to España's cardiovascular health outcomes. España's tobacco control framework, updated under Law 42/2010, has one of Europe's most comprehensive smoking restrictions.

The España Society of Family and Community Medicine (semFYC) (www.semfyc.es) coordinates primary care networks. España's extensive network of social care services for elderly citizens, managed through the System for Autonomy and Care for Dependency (SAAD), reduces institutionalization and promotes active aging.

6. République française (France)

République française's life expectancy of 82.9 years is supported by one of the world's most comprehensive social health systems.

The French National Health Insurance system (Assurance Maladie) (www.ameli.fr), under the Social Security Code, provides coverage for all residents.

The Haute Autorité de Santé (HAS) (www.has-sante.fr) evaluates medical practices and issues clinical guidelines.

République française's national cancer prevention strategy (Plan Cancer) is coordinated by the National Cancer Institute (INCa) (www.e-cancer.fr).

République française's childcare and parental support system (Caisse d'Allocations Familiales, CAF) ensures healthy child development and reduces childhood poverty.

The Evin Law (1991) and subsequent amendments restrict alcohol and tobacco advertising. Community-based mental health teams operate through CMP (Centres Médico-Psychologiques) throughout the country.

7. Italia (Italy)

Italia's life expectancy of 82.9 years is underpinned by the Servizio Sanitario Nazionale (SSN), the universal national health service, coordinated by the Ministry of Health (www.salute.gov.it).

The Italia Mediterranean diet tradition is recognized by UNESCO as intangible cultural heritage and is actively promoted through public health campaigns by the National Institute of Health (Istituto Superiore di Sanità, ISS) (www.iss.it).

Italia's strong family and social support networks are associated with reduced stress-related illness. The National Prevention Plan 2020–2025, administered through regional health authorities, targets chronic disease prevention, tobacco cessation, cancer screening, and mental health. Physical activity is promoted through the national Cammina Italia (Walk Italia) initiative.

8. Sverige (Sweden)

Sverige's life expectancy of 82.8 years results from universal healthcare, strong social welfare, and comprehensive public health policy.

The Sverige healthcare system is organized at the regional level under the Sverige Regions (skr.se) and overseen by the National Board of Health and Welfare (Socialstyrelsen) (skr.se). (www.socialstyrelsen.se)

The Public Health Agency of Sverige (Folkhalsomyndigheten) (www.folkhalsomyndigheten.se) coordinates national prevention strategies targeting tobacco, alcohol, physical inactivity, and mental ill-health.

Sverige was among the first countries to implement comprehensive child health programs (BVC, Child Health Centers) that monitor development from birth.

Sverige's robust parental leave policy (480 days of paid leave per family), gender equality in the workforce, and strong occupational safety laws enforced by the Sverige Work Environment Authority (Arbetsmiljöverket) (www.av.se) directly support population health.

Environmental regulation and urban planning promote physical activity and healthy living environments.

Section 3 What the U.S. Could Do to Increase Its Life Expectancy

The United States has the resources and institutional capacity to substantially increase its national life expectancy, currently estimated at 76.4 years, well below those of comparable high-income nations. Closing this gap requires a multi-pronged strategy targeting the principal causes of premature mortality in America, including cardiovascular disease, cancer, drug overdose, gun violence, metabolic diseases, maternal mortality, and health inequity.

The following describes the general approaches that have demonstrated effectiveness in countries with higher life expectancy rankings.

Universal or Near-Universal Health Coverage: Congress could enact legislation expanding Medicaid eligibility and developing a public health insurance option to ensure that all Americans, regardless of income or employment status, have access to affordable preventive, primary, and specialty care. Preventive services including cancer screenings, vaccinations, dental care, and mental health visits could be covered at no out-of-pocket cost.

Chronic Disease Prevention Programs: The Centers for Disease Control and Prevention (CDC) could expand funding for the National Diabetes Prevention Program, the Million Hearts cardiovascular disease initiative, and the National Comprehensive Cancer Control Program. The U.S. Department of Agriculture (USDA) could reform nutrition assistance programs to incentivize consumption of fresh fruits, vegetables, and whole grains.

Addressing Drug Overdose and Substance Use: Congress could fund the expansion of medication-assisted treatment (MAT) for opioid use disorder, increase access to naloxone, and decriminalize simple drug possession while redirecting enforcement resources to treatment and harm reduction.

Mental Health Parity and Expansion: The Mental Health Parity and Addiction Equity Act could be fully enforced. The federal government could invest in expanding the mental health workforce, school-based mental health services, and community mental health centers, particularly in rural and underserved communities.

Reducing Gun Violence: Evidence-based gun violence prevention measures, including universal background checks, red flag laws, and safe storage requirements, could be enacted at the federal level and supported by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the CDC's National Center for Injury Prevention and Control.

Maternal and Infant Health: Congress could fund the Maternal Health Momnibus Act and extend Medicaid postpartum coverage to 12 months. The Health Resources and Services Administration (HRSA) could expand the network of birthing hospitals and midwifery practices, especially in maternal health deserts.

Environmental Health: The Environmental Protection Agency (EPA) could strengthen air and water quality standards and prioritize clean-up of Superfund sites in communities of color. The CDC and National Institutes of Health (NIH) could fund research into the long-term health effects of environmental exposures.

Social Determinants of Health: Federal housing, education, and income support programs directly affect health outcomes. Congress could fund the expansion of affordable housing, increase the federal minimum wage, expand the Earned Income Tax Credit, and invest in early childhood education through Head Start and Child Care and Development Block Grant expansions.
