More than one in four older adults in the United States are socially isolated, according to federal data, as the U.S. Surgeon General has declared loneliness a public health epidemic—one that carries health risks comparable to smoking 15 cigarettes a day. The crisis has grown so severe that lawmakers are now proposing millions in federal funding to combat social isolation among seniors and people with disabilities. New AARP research finds that 40% of U.S. adults age 45 and older are lonely, up from 35% in 2018, with men now more likely to report loneliness than women—a significant shift from previous years. Socially isolated seniors face a 45% greater risk of early mortality, a 31% greater risk of dementia, and a 14% higher risk of Alzheimer’s disease, making loneliness one of the most pressing—and underrecognized—public health crises facing the nation.

Who Is Affected

Older adults aged 65 and older
Nearly one in four seniors experience social isolation, defined as the objective absence of social relationships. Physical changes associated with aging—reduced mobility, chronic illness, and loss of family and friends—place older adults at increased risk.

Adults in midlife (ages 45-59)
The highest rates of loneliness are found among adults in their 40s and 50s, with 46% reporting loneliness. This age group often juggles careers, children, and caring for aging parents while their social circles shrink.

Men
For the first time since AARP began tracking the data in 2010, men are now more likely than women to report loneliness (42% vs. 37%). Men are also more likely than women to report having no close friends (17% vs. 13%).

People with disabilities
Over one-third of adults and people with chronic disabilities report experiencing loneliness, and both groups face disproportionate rates of severe loneliness.

Low-income seniors
Seniors living in poverty face elevated risk of social isolation, compounded by limited access to transportation, healthcare, and community resources.


Health Risks of Loneliness

The health consequences of loneliness are severe and well-documented:

Early Mortality
Socially isolated seniors face a 45% greater risk of early mortality—a risk comparable to smoking 15 cigarettes a day. Research has shown that loneliness is consistently associated with an elevated risk of death across statistical approaches.

Cognitive Decline
Loneliness is linked to a 31% greater risk of dementia and a 14% higher risk of Alzheimer’s disease. A 10% increase in reports of feeling lonely was associated with an 8%-9% increased risk of severely impaired cognitive function.

Cardiovascular Disease
Social isolation is independently associated with cardiovascular mortality. Research has shown isolation significantly increases the risks of heart disease and stroke, comparable to smoking, alcohol, and obesity.

Depression and Anxiety
Among seniors attending senior centers or living in senior public housing, 20% report symptoms consistent with depression or anxiety—about three times the national average. An additional 30% report experiencing milder symptoms of anxiety, depression, or loneliness.

Healthcare Costs
Social isolation among older adults accounts for an estimated USD 6.7 billion annually in excess Medicare spending, largely due to increased hospitalizations and emergency department visits.


Government Response

Surgeon General Advisory
In May 2023, U.S. Surgeon General Vivek Murthy issued a landmark advisory declaring loneliness and social isolation a public health epidemic. The advisory warned that weak social connection raises the risk of early death about as much as smoking 15 cigarettes a day.

SILO Act (2026)
On June 17, 2026, Senators Chris Murphy (D-Conn.) and Kirsten Gillibrand (D-N.Y.) introduced the Addressing Social Isolation and Loneliness in Older Adults (SILO) Act. The legislation would provide USD 62.5 million in annual grant funding to support area agencies on aging and community-based organizations in:

  • Providing training for staff to combat and prevent social isolation
  • Conducting outreach to at-risk individuals
  • Developing community-based interventions
  • Connecting at-risk individuals with social and clinical supports
  • Evaluating program effectiveness

The SILO Act is endorsed by USAging, the Elder Justice Coalition, and the Foundation for Social Connection Action Network.

National Strategy for Social Connection Act
A companion bill, the National Strategy for Social Connection Act, would establish an Office of Social Connection Policy and a federal strategy addressing housing, transportation, health, education, and labor.

State and Local Initiatives
States and community organizations are also taking action. In June 2026, Element Care received a USD 100,000 grant from the Cummings Foundation to launch programs targeting senior isolation. The Humana Foundation announced over USD 12 million in new grants to end senior loneliness, including a USD 3 million investment in Older Adults Technology Services (OATS) from AARP.


Expert Analysis

On the Scope of the Crisis
“Loneliness among older adults is the equivalent of smoking a pack of cigarettes a day,” said Bill McDonald, president of AARP New York. The comparison underscores the severity of the public health threat.

On Rising Loneliness Among Men
The AARP research reveals a notable shift: men are now more likely than women to report loneliness (42% vs. 37%). This represents a change from 2018, when roughly equal numbers of men (34%) and women (36%) reported being lonely. The findings suggest that social isolation may be affecting men differently than in previous years.

On Midlife Pressures
“In midlife, people are often juggling careers, children, and caring for aging parents while their social circles shrink,” said Debra Whitman, AARP Executive Vice President and Chief Public Policy Officer. “These pressures can increase stress and offer fewer chances to meaningfully connect with others”.

On Technology and Connection
While 57% of adults aged 45 and older rely on technology to stay connected with friends and family, technology can deepen isolation for those who lack existing in-person networks. Nearly a quarter (24%) of lonely adults say technology leads to fewer close friendships. At the same time, 23% of lonely adults are interested in AI technologies for companionship and conversation.

On the Economic Impact
The USD 6.7 billion annual cost in excess Medicare spending highlights the economic burden of social isolation. As one analysis noted, “Social isolation among older adults alone accounts for about USD 6.7 billion in excess Medicare spending a year, largely due to increased hospitalizations”.


What Happens Next

SILO Act Legislation
The Addressing Social Isolation and Loneliness in Older Adults (SILO) Act was introduced in the Senate on June 17, 2026, and has been referred to the Committee on Finance. If passed, it would provide USD 62.5 million in annual grant funding to combat senior isolation.

National Strategy for Social Connection
A companion bill would establish an Office of Social Connection Policy and a federal strategy addressing multiple sectors including housing, transportation, health, education, and labor.

State and Community Programs
States and community organizations continue to launch programs targeting senior isolation. The Humana Foundation’s USD 12 million investment and Element Care’s USD 100,000 grant are examples of growing momentum to address the crisis.

Awareness and Outreach
Advocates emphasize the importance of normalizing conversations about loneliness and mental health. “I think everybody is getting more comfortable talking about personal mental health concerns,” said Dr. Patrick Raue, a clinical psychologist at the University of Washington School of Medicine. “That’s so important to normalize the experience that when we’re struggling, when we’re feeling disconnected, when we’re feeling lonely, when we’re feeling depressed or anxious, it’s OK to talk about that”.


Background

Surgeon General Advisory
In May 2023, U.S. Surgeon General Vivek Murthy issued “Our Epidemic of Loneliness and Isolation,” an 82-page advisory declaring loneliness a public health crisis. The advisory warned that the health effects of loneliness are comparable to smoking 15 cigarettes a day.

CDC Data
The CDC has identified older adults as being at increased risk for social isolation and loneliness due to changes in physical abilities, reduced mobility, chronic illness, loss of family and friends, and living alone. Nearly one-quarter of older adults experience social isolation.

AARP Research
AARP’s research on loneliness among adults aged 45 and older has tracked the issue since 2010. The latest findings show loneliness has increased from 35% in 2010 and 2018 to 40% in 2026. The research also reveals a notable gender shift, with men now more affected.

National Institute on Aging
The National Institute on Aging has confirmed that 1 in 4 adults aged 65 and older experience social isolation. Social isolation is defined as the objective absence of social relationships, distinct from loneliness, which is the subjective feeling of isolation.
