Findings suggest that housing for EFC residents tends to be long-lasting and relatively stable in California. Modest variations in mobility by residential type and by experiences in foster care before age 18 underscore the importance of integrating housing and psychosocial resources during independent living planning processes. The commonality of out-of-county residence should be considered when determining housing and transportation expenses for residents, given its potential implications for access to medical and behavioral health care, academic institutions, and employment opportunities for young adults receiving EFC services.
