Descriptive text is not available for this image Basics

Description

  • Lacking a fixed, regular, and adequate nighttime residence.
  • Chronic homelessness: lacking fixed, regular housing for at least 1 year, or at least four episodes of being unhoused in the past 3 years for a combined length of at least 1 year.
  • People struggling with homelessness often have complex and chronic medical illnesses such as mental illness, substance use disorders, and physical disabilities (1).

Epidemiology

Incidence

  • Increasing since 2017 nationwide; 6% overall increase year-to-year, expect for this past year which showed >12% increase over the previous year. This marked the largest increase since data collection began in 2007.
  • The COVID-19 pandemic disrupted accounting of unsheltered people, but conditions during the pandemic may have increased the incidence (1).

Prevalence

In 2023, 0.19% of the U.S. population (approximately 653,100 individuals) experienced homelessness on any given night: 61% in sheltered locations and 39% in unsheltered locations (1).

  • 5% are veterans, 28% are families with children, 5% are unaccompanied youth (age <25 years) and 22% are chronically homeless individuals.
  • 50% of the homeless population is white.

Risk Factors

  • Poverty
    • 2024 federal poverty level: $31,200 annual income for four-person household in the lower 48 states and District of Columbia, slightly higher in Alaska and Hawaii (2)
    • In 2022, 11.5% of U.S. population below federal poverty line
  • Unemployment: U.S. rate 4.3% in July 2024 (U.S. Bureau of Labor Statistics)
  • Lack of affordable health care: In 2023, 7.7% of U.S. population (334 million) were uninsured for the entire calendar year (3).
  • Lack of affordable housing: <30% of gross income for housing costs, including utilities; roughly 40.9 million U.S. households spend >30% on housing costs; 19 million households spend ≥50% of income on housing.
  • Intimate partner violence (IPV): 12% of overall persons experiencing homelessness and about 20% of families experiencing homelessness report IPV; IPV often involves exertion of psychological and financial control that leaves survivors with poor credit, limited support, and few resources.
  • Veterans: decreasing due to policy changes; decreased by 50% over a decade (2010 to 2020) (2)
  • Transgender individuals: 0.6% identify as transgender and 0.6% as gender nonconforming (2)
  • Addiction disorders: 46% report substance use as a major factor contributing to homelessness (1).
  • Psychiatric illness: 25% of adults experiencing homelessness (1)
  • Postincarceration: 50,000 people each year enter homeless shelters from jails/prisons (1).

General Prevention

  • Policy and funding for community programs to provide emergency/rapid housing, housing stabilization, and case management services; the CARES Act of 2020 and the American Rescue Plan Act of 2021 provide funding for permanent housing. Over the past 5 years, the fastest growing forms of assistance include rapid rehousing and “other permanent housing.”
  • Increased Medicaid eligibility, expanded home- and community-based services, and case management for people experiencing homelessness.
  • HUD: increasing permanent supportive housing units; increasing services for veterans, families with children, and those with disabilities
  • Social justice policy recommendations: permanent affordable housing; foreclosure and homelessness prevention; increased funds for HUD McKinney-Vento programs (emergency, transitional, and permanent housing) and National Housing Trust Fund, rural homeless assistance, universal health care, universal livable income, employment/workforce services; prevention of hate crimes against the homeless, decriminalization of homelessness
