Homelessness  also known as a state of being unhoused or unsheltered – is the condition of lacking stable, safe, and functional housing.

The legal status of homeless people varies from place to place. United Kingdom government homeless enumeration studies also include people who sleep in a public or private place, which is not designed for use as a regular sleeping accommodation for human beings. Homelessness and poverty are interrelated.

The general category includes disparate situations, such as living on the streets, moving between temporary accommodation such as family or friends, living in boarding houses with no security of tenure,
and people who leave their domiciles because of civil conflict and are refugees within their country.

Primary homelessness (or rooflessness). This category includes persons living in the streets without a shelter that would fall within the scope of living quarters.

Secondary homelessness. This category may include persons with no place of usual residence who move frequently between various types of accommodations

There is no methodological consensus on counting homeless people and identifying their needs; therefore,
in most countries and cities, only estimated homeless populations are known.

Everyone has the right to a standard of living adequate for the health and well-being for themselves, including food, clothing, housing, and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.

Many countries and individuals do not consider housing as a human right.

Former U.S. President Jimmy Carter addressed this issue in a 2017 interview, saying, "A lot of people don't look at housing as a human right, but it is." His view contrasts with many Americans who do not believe housing is a basic human right.
