One-child base rate at Iowa's median income
17% of $65,429, the Census ACS 2022 median household income for Iowa, 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.
OCSE guideline posture brief

National context
Each bar counts states with a published one-child base rate in that 3-point band. Iowa's lower-third 17% mark is highlighted. Counts are exact from the 51-jurisdiction dataset.
Iowa's 17% published one-child base rate is higher than 6 of 51 recorded state rates. The comparison describes guideline starting percentages, not a complete child-support estimate. Iowa sits in a lower-rate band on this histogram.

Dense order-establishment share
Iowa sits in the top third on OCSE P-64 order share (94.1% · #5 of 51).
Iowa posts 94.1% of its Title IV-D caseload with an established order - denser than two-thirds of reporting jurisdictions on OCSE P-64. The Income Shares schedule (43 jurisdictions on this model) opens lower than most peers before deviations. Unlike capped states, the formula applies to full reported income before deductions. Nearest one-child rate peer: Connecticut at 17% (Δ 0.0 pts). Iowa also builds a parenting-time credit into the guideline - relevant when a dense order book meets substantial overnight time. A percentage figure alone does not determine the dollar amount - compare Iowa to other guideline models →
On OCSE FY2023 tables, Iowa ranks #5 of 51 on order-establishment share and #28 by caseload volume (~$2,106 distributed per case, our calc on P-4/P-52). Source: HHS Office of Child Support Services, FY 2023 Preliminary Report.
Iowa 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. That lower-third starting rate is the schedule's open before deviations.
