Current Number of Americans Living Alone
As of the most recent public data, roughly 37 million households in the United States are single-person households, representing about 28 percent of all US households. This figure comes from the US Census Bureau's American Community Survey and related household surveys, which track household size and composition annually. The number has grown steadily over recent decades as marriage rates declined, fertility dropped, and more adults chose or needed to live independently.
The share of people living alone is highest among adults aged 65 and older, but the largest absolute increase has been among younger and middle-aged adults, especially in major metro areas. In cities such as New York, Los Angeles, and Chicago, single-person households make up a much larger share of total households than the national average, driven by housing costs, career mobility, and changing social norms.
Demographic Breakdown and Key Trends
By age group, adults aged 25 to 34 and 65 and older have the highest rates of living alone, while adults under 25 are more likely to live with roommates or parents. Gender patterns show that older women are more likely to live alone than older men, reflecting differences in life expectancy and marital status. Racial and ethnic differences exist, with non-Hispanic white adults and Asian adults somewhat more likely to live alone compared with Hispanic and Black adults, after adjusting for age and income.
Economic and Housing Factors
Rising housing costs in many markets push some people toward smaller, single-person units, while higher incomes allow others to afford independent living. The growth of single-person households has supported demand for smaller apartments, studio units, and single-family rentals, influencing developers and investors focused on urban and suburban housing.
Implications for Business, Policy, and Daily Life
Companies in housing, retail, food service, and healthcare have adapted to the rise of solo living by offering smaller product sizes, flexible leases, and delivery services tailored to single households. Financial planners and employers also pay attention to the economic footprint of single-person households, including savings rates, spending patterns, and demand for rental housing.
Public policy discussions focus on affordable housing supply, tenant protections, and support services for older adults who live alone and may face isolation or health risks. The increase in solo households also affects everything from utility usage and home insurance to the design of consumer products and urban planning strategies across major US metros.
