This study analyzed factors that influence how long families stay in homeless shelters. It found that families who stay longer tend to have more children, receive housing subsidies, and screen positive for alcohol or drug use. Those who leave shelters sooner are more likely to have another adult in the household or less housing debt. The findings suggest shelters can become long-term housing when families wait for subsidies, and some families may need more support for substance use before moving on. The implications are that systems should focus on rapid rehousing, limiting shelter stays, and providing targeted services to help families transition successfully.
