Living Alone Statistics: One-Person Households
Published September 15, 2026 · StatsGalore
One-person households in 2025 [1]
The United States had 39.7 million one-person households in 2025. They represented 29% of all households, up from 20% in 1975, according to Census Bureau family and living-arrangement estimates. [1]
The numbers
| Measure | 1975 | 2025 | Source |
|---|---|---|---|
| One-person share of all households | 20% | 29% | [1] |
| Number of one-person households | Not reported in this release | 39.7 million | [1] |
Households and people have different denominators
The 29% figure is a share of households. It does not mean 29% of Americans live alone. A household with several residents contributes one household to the denominator but several people to a population count.
This is one of the most important distinctions in interpreting living-arrangement statistics. To measure the share of people living alone, the number of people in one-person households must be compared with the appropriate population, not with the household count.
[1]The long-term change
The reported share increased by nine percentage points between 1975 and 2025. Percentage points describe the difference between two percentages; they are not the same as a nine-percent relative increase.
This comparison shows a change in the composition of households. It does not, on its own, explain why the change occurred. Age structure, marriage patterns, economic conditions, and other factors can affect household formation.
[1]Living alone is not a relationship status
A one-person household describes who lives at an address under the survey's household definition. It does not tell us whether a person is dating, has close family nearby, or receives frequent visits.
Likewise, it is not a measure of loneliness or social isolation. Those experiences require direct questions or other evidence. Inferring emotional well-being from a household count would overreach the data.
[1]What a household survey can tell us
The Census Bureau's figures are useful for understanding demand for different housing arrangements and the changing mix of household types. They describe an important part of how people organize daily life.
They do not establish that every one-person household occupies a small home, has a low income, or needs the same services. A national category can contain people with very different circumstances. The release's survey estimates also carry sampling and nonsampling uncertainty.
