On a single night in 2018, roughly 553,000 people were experiencing homelessness in the United States. About two-thirds (65%) were staying in sheltered locations—emergency shelters or transitional housing programs—and about one-third (35%) were in unsheltered locations such as on the street, in abandoned buildings, or in other places not suitable for human habitation. Homelessness increased (though modestly) for the second year in a row. The number of homeless people on a single night increased by 0.3 percent between 2017 and 2018. The increase reflects declines in the number of people staying in emergency shelters and transitional housing programs being offset by increases in the number of people staying in unsheltered locations. Between 2017 and 2018, the unsheltered population increased by two percent (or 4,300 people).
