Do you have a source? With a brief search I was unable to find a credible source that supports your claim. These papers suggest that anyone involved in child-welfare as a child has a higher risk, unless they can go back home. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5644395/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5644395/ > Youth aging out of foster exhibit similar rates of literal homelessness and housing instability as other child welfare-involved youth, while youth who reunify after out-of-home placement in adolescence experience the lowest probability of literal homelessness https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3969135/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3969135/ > Consistent with earlier studies, we found that youths aging out of foster care are at high risk of becoming homeless during their transition to adulthood. Specifically, 36% of the 624 Midwest Study participants whose outcomes we could observe reported at least 1 episode of homelessness by age 26 years. That figure could be as low as 31% or as high as 46% depending on the rate of homelessness among those with unobserved outcomes, which means that, at a minimum, nearly one-third of the study participants were homeless at some point after leaving foster care. Obviously these studies are talking about risk and not a percent of the population, but it does seem that being effectively a homeless child increases risk of being a homeless adult at some point. The latter study mentions several mechanisms to ameliorate the problem.
