How to Read Foster-Care Reunification Rates
Reunification is one documented reason a child can leave foster care. This guide explains exactly how PlainFoster derives the FY2022 rate, what a state comparison can support, and where the federal tables stop.
The measure across 49 qualifying jurisdictions
Nationally 45.2% of FY2022 exits were reunifications, but the middle half of qualifying jurisdictions runs from 40.4% to 51.0%, so a single national figure hides most of what separates one state from another.
- 45.2%
- National share of FY2022 exits
- 45.9%
- Median qualifying jurisdiction
- 40.4%-51.0%
- Middle half of jurisdictions
- 49
- Jurisdictions with at least 500 exits
Jurisdictions below 500 FY exits are excluded from the spread because a handful of cases can swing the rate. The measure describes how cases closed, not whether a system performed well.

The Measure in One Sentence
PlainFoster's reunification rate is the number of FY2022 exits coded as reunification with a parent or primary caretaker divided by all exits in the same jurisdiction report.
The result is a share of discharges, not a share of all children who were in care during the year.
It is also not a count of families receiving reunification services or a forecast of what will happen in an individual case.
The Numerator
The numerator comes from the discharge-reason table in each FY2022 AFCARS jurisdiction report.
PlainFoster uses the row for reunification with a parent or primary caretaker.
That row counts recorded foster-care exits during the federal fiscal year.
It does not count a child merely because reunification was listed as a case-plan goal.
It does not include exits recorded under adoption, guardianship, living with other relatives, emancipation, transfer, runaway, or death.
The Denominator
The denominator is the jurisdiction report's total number of exits during FY2022.
Using all exits answers a narrow question: what share of recorded discharges ended through reunification?
A different denominator would answer a different question and should not be labeled as the same rate.
PlainFoster keeps the report's numerator and denominator together so the displayed percentage can be reproduced.
The ETL also checks that the extracted discharge categories do not exceed total exits.
The FY2022 National Context
Across the 52 reports used for the national calculation, PlainFoster derives a 45.2% reunification share from 201,372 reported exits.
This national rate is weighted by each jurisdiction's exit count.
A jurisdiction with many exits therefore contributes more to the national result than a jurisdiction with few exits.
The public state table covers the 50 states and the District of Columbia.
The national aggregate also includes Puerto Rico because the official national workbook and jurisdiction-report set include it.
PlainFoster labels these scopes separately rather than forcing the state sum to equal the broader national total.
How the State Ranking Works
The reunification metric page orders jurisdictions with at least 500 FY2022 exits by their rate (Delaware and D.C. are omitted for small-N volatility).
Higher percentages appear first because the metric definition marks higher values as favorable for ordering.
The page also reports the unweighted mean across the qualifying cohort.
An unweighted mean gives every jurisdiction equal influence, regardless of the number of exits.
That mean is not the same statistic as the weighted national rate.
The table labels its comparison baseline as the jurisdiction mean to keep that distinction visible.
What a Higher Rate Does Show
A higher rate shows that reunification made up a larger share of the jurisdiction's recorded exits in that release.
It can support a descriptive comparison of the discharge mix across states.
It can also help a researcher identify jurisdictions for closer review in source reports or policy documents.
The measure is most useful when the reader keeps the exit count, reporting year, and other discharge categories in view.
What a Higher Rate Does Not Show
The rate does not establish that reunification decisions were safe or durable.
It does not identify why a jurisdiction recorded more or fewer reunifications.
It does not adjust for the ages, needs, placement histories, or legal circumstances of children in the exit cohort.
It does not measure the quality of casework, courts, legal representation, family services, or post-exit support.
It does not show whether an individual family should reunify or when that should occur.
Those questions require information beyond the jurisdiction-level AFCARS table.
Why PlainFoster Does Not Pair It With a Re-entry Rate
A previous version of the site displayed a re-entry measure.
During the 2026 source-lineage audit, that value could not be recreated from the archived source path the database claimed to use.
PlainFoster therefore removed the public re-entry field instead of carrying forward a precise-looking number without reproducible lineage.
The field can return only when an exact publisher file, cohort definition, follow-up period, unit, and tested parser are documented.
Until then, this guide does not infer placement durability from the reunification rate.
Reunification and the Profile Grade Are Different
A state's letter grade is not assigned from its reunification percentage.
PlainFoster calculates within-release percentile ranks for four measures.
Those measures are reunification, adoption, aging out, and median length of stay.
The four ranks receive equal weight in the composite.
A state can rank highly on reunification and still receive a different profile band after the other three measures are included.
The grade remains a narrow editorial summary, not an official assessment of child-welfare quality.
A Practical Reading Checklist
- Confirm that the page and source use the same fiscal year.
- Read the numerator definition before comparing percentages.
- Check the total exit count to understand the scale behind the rate.
- Distinguish the unweighted jurisdiction mean from the weighted national rate.
- Review adoption and aging-out shares as separate discharge outcomes.
- Keep the composite grade separate from the single-measure rank.
- Do not infer a cause from the cross-state ordering.
- Open the original jurisdiction report for consequential research.

Frequently Asked Questions
What does the AFCARS reunification rate measure?
PlainFoster divides exits coded as reunification with a parent or primary caretaker by all reported foster-care exits in the same FY2022 jurisdiction report.
Is a higher reunification rate always better?
No. The rate describes the mix of discharge reasons. It does not by itself measure child safety, placement durability, case mix, service quality, or whether a particular decision was appropriate.
Why can state rates differ?
The federal tables show that rates differ but do not identify a cause. State laws, courts, reporting systems, case mix, and available services can all vary.
Is the PlainFoster grade a reunification grade?
No. The profile grade equally combines percentile ranks for reunification, adoption, aging out, and median length of stay. The reunification page is a separate single-measure ranking.
According to the U.S. Children's Bureau (Administration for Children and Families), foster-care counts and discharge outcomes are published in AFCARS workbooks and jurisdiction reports. Every figure on PlainFoster is rebuilt from those federal tables; no number is typed in by an editor. FY2022 reunification counts are divided by total exits from the same ACF AFCARS jurisdiction report; the national rate is weighted across all 52 reports. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2026-07-30. AFCARS figures are federal fiscal-year foster-care counts and discharge rates from jurisdiction reports - not child-welfare quality rankings, court-performance scores, case-level advice, or real-time caseload status.
