What happens after eighteen

8,183

children and young adults were in out-of-home care in Arizona as of December 31, 2025. Of those, 1,097 were 16 or 17, and 1,109 were already 18 or older.

546derived

young people left Arizona's out-of-home care by reaching the age of majority during 2025: 284 between January and June, and 262 between July and December.

546 is the sum of the two reporting periods DCS publishes, not a figure DCS publishes directly. The count has fallen three years running, so it is not an annual average.

was the median age at which young people left Arizona foster care by reaching the age of majority between July and December 2025. The average was 19.6. Aging out is not something that happens at eighteen.

1,113

young adults aged 18 to 21 were in Arizona out-of-home care as of June 30, 2026, up from 1,009 a year earlier and 881 in state fiscal year 2023. This population is growing while Arizona's overall foster care population falls.

66%

of 17 to 20 year olds entering or already enrolled in Arizona's Extended Foster Care had no federally required transition plan: 233 of 355, found and documented by the Department's own staff as of February 2024.

These 355 young people had already found the programme. This measures whether the state prepares them once they are in it, not whether anyone told them it existed. DCS agreed with every recommendation; no follow-up report had been published as of August 2026.

26%

of young people with foster care experience surveyed at age 21 reported having been homeless at some point within the previous two years. At age 19 it was 21%. Among those who answered at all three ages, 44% reported at least one experience of homelessness by 21.

36%

of American Indian or Alaska Native young people with foster care experience reported stable housing across ages 19 and 21, against 66% of all respondents.

American Indian and Alaska Native young people are fewer than 2% of national NYTD respondents, so read this as evidence of a large disparity rather than a precise rate.

20% / 45%

was the split in homelessness between ages 18 and 21 among 616 young people followed in California: 20.1% of those who stayed in care the whole time, against 44.7% of those who left and never returned.

California, not Arizona, and observational: young people who stay in care differ from those who leave in ways beyond care status, so read it as association and not cause. Those who left and came back were at 45.1%, no better than those who never came back, and 18.9% of those in extended care had been homeless while still in it. An older Midwest study found extended care delayed homelessness rather than preventing it, with the advantage gone by 23. The evidence genuinely diverges.

Chapin Hall, Memo from CalYOUTH: Predictors of Homelessness at Age 21 · May 2020

21

is the age Arizona's Extended Foster Care runs to. Juvenile court dependency jurisdiction ends at 18, but a young adult in DCS custody on their 18th birthday may voluntarily remain in or return to care until their 21st birthday, provided they sign an agreement with DCS and are in school or training, working at least 80 hours a month, in an activity that removes barriers to employment, or unable to do so for a documented medical reason.

Support ends ON the 21st birthday, not through age 21. A young adult who declined at 18 can ask to re-enter any time before turning 21.

15

working days is all DCS has to answer a young adult who asks to re-enter extended foster care and is refused. The refusal must be in writing, with the reason and with the young adult's grievance and appeal rights. A no is not the end of the conversation.

Agency policy and administrative rule, not statute. The policy predates the 2025 changes in A.R.S. § 8-521.03 and DCS has not been asked to confirm it still operates this way. The same policy routes re-entry through the Transitional Independent Living Program, so TILP is the first call, not DCS intake.
