Life clearly has unique challenges for children who are placed in foster care. Some of these children might suffer from a variety of trauma, such as:

In FY2024, 15,379 youth exited foster care through emancipation, representing 9% of all exits (AFCARS FY2024). An additional 10% of exits were youth aged 18–23. Research consistently shows that youth who age out face significantly worse outcomes in education, employment, housing, and justice system involvement than their peers.
Of the youth who are aging out of foster care (18 years old and up):
These statistics suggest that many youth aging out of foster care are not prepared to be self-sufficient when they leave the system, but research shows that extended foster care programs significantly improve outcomes.
Former foster youth experience homelessness at dramatically higher rates than the general population. A 2024 study found that 22–30% of youth who age out become homeless during the transition to adulthood, compared to a 4% lifetime prevalence in the general population.

According to AFCARS FY2024 data, 328,947 children are in the U.S. foster care system as of September 30, 2024. This marks the sixth consecutive year of decline, down from a peak of 407,332 in 2020. During FY2024, 170,943 children entered care and 176,730 exited. California has the most children in care with 38,490.
Research shows that 22–30% of youth who age out of foster care experience homelessness during the transition to adulthood, compared to a 4% lifetime rate for the general population. In California specifically, approximately 31% of transition-age foster youth experience homelessness.
In FY2024, 15,379 youth exited foster care through emancipation (aging out), representing 9% of all exits. The emancipation rate has decreased from 11% in 2009, partly due to more states extending foster care beyond age 18. In Los Angeles County alone, approximately 1,000 youth age out each year.
Youth who age out face significant challenges: 22–30% experience homelessness, only half are employed by age 24, and 8–12% earn a college degree compared to 49% nationally. Over 40% are incarcerated by age 20. However, research shows that extended foster care programs significantly improve outcomes, youth who stay in care past 18 are 69% more likely to earn a high school diploma and 41% less likely to experience homelessness.
According to AFCARS FY2024 data, neglect is the most common reason at 55% of entries, followed by caretaker drug use (31%), physical abuse (13%), domestic violence (9%), and inadequate housing (9%). Children can enter care due to multiple circumstances, so these percentages overlap. 69% of children entering foster care have reunification as their initial permanency plan.
Approximately 90% of children in foster care have experienced at least one traumatic event, and 41% had a diagnosed mental health condition before even entering care. Nearly half have been exposed to 4 or more types of traumatic events. Common conditions include PTSD, depression, anxiety, and ADHD. Foster youth are also at higher risk for substance use disorders.
