Per the U.S. Department of Housing and Urban Development (HUD), "On a single night in 2018, roughly 553,000 people were experiencing homelessness in the United States." Given that the U.S. population in 2018 was 328,000,000, this amounts to about one out of every 600 people. The same HUD report 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."
