The housing crisis is closely linked with another crisis: homelessness*, a persistent issue even in the world’s wealthiest societies4,5. While individual circumstances leading to homelessness are diverse, at a population level, the largest predictor is a lack of affordable housing6,7, which has been associated with a 38% increase in homelessness in the largest American cities in the past year8. The two crises are exacerbated by unforeseen circumstances such as natural disasters, humanitarian crises, and economic downturns9.
