The Child Support Machine Costs More and Collects Less
Summary
In fiscal year 2024 the federal-state child support program distributed $26.65 billion to families — down 15% since 2020 — while the bill for running it climbed to $6.64 billion. The return on every dollar spent has fallen for five straight years, from $5.51 to $4.24, on a staff of roughly 48,000 handling a shrinking caseload.
Follow the dollar
Almost none of the money the program collects stays in government hands. Of $26.65 billion in FY2024 distributed collections, per Table P-1 of the ACF data tables, 93.8% — $24.99 billion — goes straight to a family. Another 3% reimburses federal and state treasuries for and foster-care assistance they already paid out; the rest is medical support, pass-through payments, and the small processing fees states are allowed to keep. This is the case for running the program at all: it is not a revenue machine for government, it is a collection service for parents owed money.

| Payments to families & foster care | $24,991.8M | 93.8% of collections |
|---|---|---|
| Medical support | $634.1M | 2.4% of collections |
| Passed through to assisted families | $150.0M | 0.6% of collections |
| Assistance reimbursement (federal & state) | $807.8M | 3.0% of collections |
| Fees withheld by states | $70.0M | 0.3% of collections |
The exchange rate is getting worse
The program's own headline metric is a ratio: distributed collections per dollar of administrative expenditure. In FY2020 it returned $5.51 for every dollar spent. By FY2024 that had fallen to $4.24 — a decline in every single year, five years running, a 23% drop in the ratio itself. The underlying numbers move in the wrong direction from both sides at once: total distributed collections fell from $31.42 billion to $26.65 billion (-15%) while total administrative expenditures rose from $6.00 billion to $6.64 billion (+10.5%), per Table P-1 of the same ACF report. Congress funds the program on the assumption that it pays for itself many times over — states are statutorily reimbursed 66 cents of every dollar of allowable spending by the federal government, per the Congressional Research Service's program overview — but the multiple the program is actually delivering keeps shrinking.

Same job, higher price tag
The staffing side complicates the easy story. Full-time-equivalent CSE staff fell only slightly, from 49,078 in FY2020 to 48,192 in FY2024, per Table P-80 — a 1.8% drop, nowhere near the collapse other federal-adjacent agencies have seen. Meanwhile the caseload the program is responsible for actually shrank faster than the staff did: 13.2 million open cases in FY2020 down to 11.65 million in FY2024, an 11.8% decline, per Table P-52. Fewer cases, almost the same headcount — cases per worker actually fell, from 269 to 242. None of that is a labor shortage. It's the opposite problem: a workforce that held roughly steady while the job in front of it got smaller, and the bill for doing it still went up. Divide total administrative spending by total caseload for each year and the per-case cost of running the program climbs from $455 in FY2020 to $570 in FY2024 — up 25% in five years, on a workload that shrank.

The takeaway
- The money mostly reaches families. 93.8 cents of every collected dollar in FY2024 was a payment to a family, not a fee retained by government — the program's core function still works as designed.
- But the machine is getting less efficient every year. The cost-effectiveness ratio fell in FY2021, FY2022, FY2023, and FY2024 — four straight declines, from $5.51 to $4.24 per dollar spent.
- It isn't an overworked-staff story. Headcount barely moved while the caseload shrank faster — the cost per case rose 25% anyway, which is a spending and collections problem, not a labor-shortage one.

Every state runs a child support agency because federal law requires one — Title IV-D of the Social Security Act, enacted in 1975, makes it a condition of running a welfare program at all. The deal was always mechanical: the federal government pays the bulk of the bill, states chase the money, and the program is graded on one number — how much it collects per dollar it costs to run. In the FY 2024 Preliminary Data Report and Tables published by the Administration for Children and Families, that grade has fallen for five consecutive years.
