When 1 in 3 children worldwide still lack safely managed drinking water, it’s a reminder that “fostering” starts long before a child ever enters a care system. Yet even in 2022 settings where basic needs like vaccinations and protection are meant to be secure, 18.7 million children under 5 had missed out on basic vaccinations, and 37 million children were living in alternative care arrangements. This post puts those gaps side by side with what foster care can change, and what it cannot.
Key Takeaways
- 0% of organizations can legally operate a child labor program in many jurisdictions; in practice, the Convention on the Rights of the Child requires states to prohibit and eliminate child labour—meaning children must not be placed in prohibited labor situations
- 1 in 3 children (33%) worldwide lived in households without access to safely managed drinking water services in 2022
- 28% of children aged 6–23 months globally did not receive basic vaccinations in 2022 (DTP3 proxy for vaccination gaps varies by data source; UNICEF/WHO coverage estimates)
- 18.7 million children under age 5 had missed out on basic vaccinations in 2022
- In 2022, 1 in 5 children experienced some form of sexual violence before age 18 in lifetime survey findings synthesized in the global status report
- In the U.S., 5% of confirmed victims in 2022 had psychological maltreatment only
- In England, 51,000 children were in need in 2023
- The licensed foster care workforce in the U.S. (foster family homes) numbered 442,000 in 2022
- In Australia, the out-of-home care rate was 10.2 per 1,000 children in 2022
- Foster care adoptions in the U.S. reached 112,000 in 2022
- The U.S. achieved a 67% reunification rate for children entering foster care in 2017 (time-limited outcomes)
- In the U.S., 28% of young adults who aged out of foster care experienced homelessness at least once (study estimate)
- In the U.S., state agencies reported about 450,000 foster care placements during 2022 (placements count used in AFCARS time-window estimates).
- 1,000,000 children in the U.S. were in foster care or guardianship through the child welfare system in 2022 (children served in out-of-home care under Title IV-E/state care).
- In the U.S., 27% of substantiated victims in 2022 were victims of physical abuse.
Foster care demand is rising worldwide, with millions affected by neglect, violence, and instability despite strong reunification efforts.
