In the United States in 2023, 161,000 people experienced homelessness, and 17% were unsheltered. The US 2023 Point in Time count captures those living on the street and in places not meant for habitation, not just people in shelters. Housing costs also show up in the data as a major driver, with homelessness risk rising by about 30% for each standard deviation increase in rent burden.
Key Takeaways
- In the US 2023 PIT, 8% of people experiencing homelessness reported substance use disorder (HUD AHAR breakdown)
- In France, 56% of people seen by homelessness services in 2023 were men (Insee/Centres d’hébergement data as reported in national homelessness review)
- A global synthesis (2020–2022 evidence base) found that housing affordability is a primary driver: for 1 standard-deviation increase in rent burden, homelessness risk rises by ~30% in observational analyses
- 2.5% of respondents in a 2019 survey of people experiencing homelessness in the European Union reported having been homeless for more than 5 years
- In 2023, 3 in 10 people experiencing homelessness in the US (30%) reported staying in a shelter the night before the Point-in-Time count (HUD PIT Count tabulations)
- US$ 4.0 billion in ARPA funds were allocated for homelessness response in 2021 under U.S. federal guidance (including Treasury/State and local allocations)
- EU Member States committed €59.5 billion under the European Social Fund+ (ESF+) 2021–2027 for social inclusion and employment—relevant to homelessness prevention and housing exclusion policies
- Finland allocated €50 million annually to housing services for long-term homelessness solutions under its housing-first approach reforms (as reported in government program materials)
- A meta-analysis found that Housing First is associated with improved housing stability, with a pooled odds ratio of 2.14 for maintaining housing (relative to standard approaches)
- A long-run study in Housing First sites reported employment/education engagement rose by 12 percentage points among participants over 18 months (peer-reviewed evaluation)
- In the US, 44% of people experiencing homelessness reported that they had been homeless before (2019 AHAR—Point-in-Time; prior episodes).
- A OECD analysis reported that increases in eviction rates are associated with higher homelessness incidence (elasticity-style relationship reported in OECD housing/homelessness evidence).
- 17% of surveyed people experiencing homelessness in the European Union reported sleeping rough (FEANTSA overview citing ETHOS-related survey findings).
- 161,000 people in the United States experienced homelessness in 2023 (HUD AHAR—Part 1 estimate for sheltered and unsheltered populations).
- 3.4 million people in the US are estimated to experience housing insecurity leading to homelessness risk annually (US housing/homelessness risk estimates used in HUD research summaries; point-in-time context).
Housing First and housing support cut homelessness and service costs, while affordability pressures and long stays worsen risk.
