The term homelessness may also include people whose primary night time residence is in a homeless shelter, in an institution that provides a temporary residence for individuals intended to be institutionalized, or in a public or private place not designed for use as a regular sleeping accommodation for human beings. Some estimate that there are about 100 million homeless people worldwide.
The United States Department of Housing and Urban Development (HUD) defines a "chronically homeless" person as "an unaccompanied homeless individual with a disabling condition who has either been continuously homeless for a year or more, or has had at least four episodes of homelessness in the past three years."
