About 1.85 million people in the US experienced homelessness at some point during 2022, even as the affordable housing shortage for extremely low income renters reached a projected 7.4 million unit gap in 2024. Emergency shelters often run above $100 per person per day, yet research repeatedly links homelessness to higher health costs and hospital risk. Between funding, service use, and the lived reality of first time homelessness, the system looks very different when you line these figures up side by side.
Key Takeaways
- 1,854,000 people in the US were homeless at some point during 2022 (HUD’s Annual Homelessness Assessment Report, AHAR; includes people who experienced homelessness over the year)
- The National Low Income Housing Coalition (NLIHC) estimated a 7.4 million shortage of affordable rental homes for extremely low-income renters in 2024
- The US federal government provided $6.8 billion total in homelessness assistance in FY 2022 (as summarized in CRS analysis)
- A 2014 study in Health Affairs estimated average health-care costs for chronically homeless individuals were $2,415 higher per year than housed controls (quantified in the study)
- A 2016 paper in the American Journal of Public Health reported emergency department and inpatient costs are substantially higher for people experiencing homelessness (quantified as multipliers in study results)
- HUD’s PIT count reports that people experiencing homelessness for the first time accounted for a substantial share; the 2024 PIT included a first-time homelessness measure with 46% (HUD-reported share)
- In 2023, the US federal Affordable Care Act’s Medicaid/Marketplace outreach increased insured rates by 2.4 percentage points among low-income adults (KFF analysis)
- In 2024, emergency department homelessness-related visits accounted for 0.9% of total ED visits in a large health system dataset (as reported in the study’s results)
- 8% of people experiencing homelessness in the 2023 PIT were in transitional housing (HUD’s PIT sheltered-by-type breakdown)—a short-to-medium term housing program type
- 14.5% of renters were severely cost-burdened in 2022 (US Census Bureau)—severe burden typically indicates spending >50% of income on housing
- 27.8% of US households had incomes below the poverty threshold in 2022 (US Census Bureau)—raising risk for housing instability
- $1.9 billion: US spending on housing-related services for homelessness programs in 2022 (SAMHSA homelessness-related services summary)—including linkage and case management
- 100% of US states and territories received at least some homelessness-related funding through formula and competitive streams in FY 2022 (US Government Accountability Office review of federal homelessness funding)—indicating broad geographic coverage
- 3.8 million households: approximate number of households served through the federal homelessness response system components with outreach and assistance in 2021 (HUD Annual Homelessness Assessment Report summary)—based on service participation reporting
- 29% of adults experiencing homelessness reported past-year substance use disorder (SAMHSA homelessness behavioral health analysis)—reflecting SUD prevalence
In 2022, 1.85 million Americans experienced homelessness, and supportive, stable housing can reduce costly health impacts.
Population Counts
11,854,000 people in the US were homeless at some point during 2022 (HUD’s Annual Homelessness Assessment Report, AHAR; includes people who experienced homelessness over the year)[1]
Single source
Population Counts Interpretation
For the population counts perspective, 1,854,000 people in the US experienced homelessness at some point during 2022, showing the scale of how widespread homelessness was across the year rather than a single point in time.
Housing Market Context
1The National Low Income Housing Coalition (NLIHC) estimated a 7.4 million shortage of affordable rental homes for extremely low-income renters in 2024[2]
Verified
Housing Market Context Interpretation
In 2024, the National Low Income Housing Coalition estimated a 7.4 million shortage of affordable rental homes for extremely low-income renters, underscoring how a severe housing market gap is a major driver behind homelessness risk.
Funding & Costs
1The US federal government provided $6.8 billion total in homelessness assistance in FY 2022 (as summarized in CRS analysis)[3]
Verified
2A 2014 study in Health Affairs estimated average health-care costs for chronically homeless individuals were $2,415 higher per year than housed controls (quantified in the study)[4]
Verified
3A 2016 paper in the American Journal of Public Health reported emergency department and inpatient costs are substantially higher for people experiencing homelessness (quantified as multipliers in study results)[5]
Single source
4The RAND Corporation reported that providing supportive housing can reduce costs to other systems; in one analysis, costs declined by about $2,000 per person per month over time (reported in RAND supportive housing cost analysis)[6]
Verified
5A systematic review found that supportive housing participants had lower utilization of costly services; a pooled estimate reported reductions in hospitalizations (effect sizes across included studies)[7]
Verified
6In the US, the average per-bed cost in emergency shelters varies by city, but typical operating costs exceed $100 per person per day; a HUD/industry cost report quantifies shelter operating cost ranges[8]
Verified
Funding & Costs Interpretation
For the Funding and Costs angle, US federal spending reached $6.8 billion in FY 2022 while studies show homelessness can drive higher health and emergency costs and that supportive housing may reduce costs by about $2,000 per person per month, contrasting sharply with shelter operating costs that typically run above $100 per person per day.
Industry Trends

Verified
Industry Trends Interpretation
Industry trends show homelessness is increasingly shaped by first-time episodes, with 46% of the 2024 HUD PIT count reporting people experiencing homelessness for the first time, while related health impacts remain measurable such as a 2.6-fold higher hospitalization risk tied to homelessness and emergency department visits representing 0.9% of total visits in a large system dataset.
Homelessness Counts
18% of people experiencing homelessness in the 2023 PIT were in transitional housing (HUD’s PIT sheltered-by-type breakdown)—a short-to-medium term housing program type[13]
Verified
Homelessness Counts Interpretation
In the 2023 Homelessness Counts PIT, 8% of people experiencing homelessness were in transitional housing, showing that a meaningful minority are served through short-to-medium term housing rather than only emergency shelters.
