One-child base rate at Missouri's median income
18% of $61,847, the Census ACS 2022 median household income for Missouri, divided across twelve months, 3% below the median state. An index for comparing states, not a case estimate: guidelines apply to the obligor's income, or to combined parental income under the Income Shares model, and a court sets the actual order. How this is derived.

Where Missouri's one-child starting rate sits
Each bar counts states with a published one-child base rate in that 3-point guideline band. Missouri is marked in its own band. Counts are exact from the 51-jurisdiction dataset.
Missouri's 18% published one-child base rate is higher than 19 of 51 recorded state rates. The comparison describes guideline starting percentages, not a complete child-support estimate.

Large Title IV-D caseload
Missouri in the heavy-caseload third
285,128 active cases put Missouri in the heaviest third by OCSE P-52 volume (#12).
Missouri carries 285,128 Title IV-D cases - a heavy-third book on OCSE P-52 volume. 43 jurisdictions share the Income Shares model with Missouri. Unlike capped states, the formula applies to full reported income before deductions - material on a large caseload. Nearest one-child rate peer: Alabama at 18% (Δ 0.0 pts). Missouri allows a parenting-time adjustment when the non-custodial parent exercises substantial overnight time. A percentage figure alone does not determine the dollar amount - compare Missouri to other guideline models →
On OCSE FY2023 tables, Missouri ranks #36 of 51 on order-establishment share and #12 by caseload volume (~$1,715 distributed per case, our calc on P-4/P-52). Source: HHS Office of Child Support Services, FY 2023 Preliminary Report.
How Missouri Calculates Child Support
Missouri uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share. Its one-child base rate is in line with the national middle range. Pair the schedule math with Missouri's thinner-than-most order-establishment share when reading enforcement.
