Homelessness in America Key Points Research suggests over 770,000 people experienced homelessness in the US in January 2024, a significant increase from previous years, highlighting the urgency of the issue. It seems likely that causes include lack of affordable housing, poverty, mental illness, and systemic inequalities, with housing shortages being the primary driver. The evidence leans toward solutions like the Housing First model, affordable housing programs, and supportive services, though challenges like funding and community resistance persist.
