Homelessness is a measurable housing and health crisis, not a distant humanitarian issue. In Europe, 3.2 million people were estimated to experience homelessness at some point in 2022. In the United States, 64% of people experiencing homelessness said they could not stay housed because rent was unaffordable.
Key Takeaways
- 3.5 million people in the EU are estimated to experience homelessness in any given year (housing exclusion estimate used in EU-level reporting)
- 17.0% of homeless adults in the US are chronically homeless (HUD PIT categories as summarized in HUD “Homelessness at a Glance”)
- 11.8% of people experiencing homelessness in the US are veterans (HUD/VA reporting on PIT veteran share)
- 35% of homeless adults in the US reported substance use disorder (SAMHSA NSHSS data)
- 7 in 10 homeless persons in the US are at risk of chronic homelessness (proportion cited for persons meeting criteria used in federal counts)
- In the US, 63% of homeless adults reported spending at least 1 day in jail or prison in the past year (National Coalition for the Homeless cited synthesis; AAPI/ACA referenced in federal research)
- In OECD countries, 4.5% of the population experience housing deprivation (overcrowding/severe lack of housing conditions used in OECD reporting)
- In the US, approximately 11.7 million renter households spend more than half of their income on rent (ACS-based estimates reported by HUD)
- In the US, 23.2% of renter households are cost-burdened (spend 30%+ on housing) (HUD/AHS/ACS-based metric summarized in HUD Housing Affordability reporting)
- In the US, supportive housing reduces homelessness: SAMHSA reports that 88% of people in supportive housing remain housed after entry (supportive housing outcomes report)
- In the US, Permanent Supportive Housing reduces homelessness: 75% of participants were housed at follow-up in a national evaluation synthesis (HUD/ABT supportive housing outcomes synthesis)
- A randomized trial of Housing First in the US found significantly fewer days homeless compared with treatment as usual (measured outcome in peer-reviewed paper)
- In Finland, Finland’s homelessness reduction strategy reduced long-term homelessness by 35% between 2008 and 2015 (government strategy results)
- In the US, emergency shelter and unsheltered costs to public systems can exceed $30,000 per person annually (reported cost-of-homelessness synthesis)
- 3.2 million people in Europe were estimated to experience homelessness at some point in 2022
Homelessness affects millions worldwide and rising housing costs drive chronic, deadly instability without rapid supportive housing.
