With the creation of the Department of Early Childhood (combining the former Office of Early Care and Education and First 5 San Francisco) and the passage of “Baby” Prop C in 2018, San Francisco is once again poised to lead the way in providing services to the city’s youngest residents. In recognition of this turning point, the Department of Early Childhood (DEC), with contributions from the Child Care Planning and Advisory Council (CPAC), Children’s Council, and the Family Resource Center (FRC) Alliance, funded this effort to map existing resources for children from birth to age 5 and their families and to identify gaps, duplications, and coordination challenges.
