One-child base rate at Arizona's median income
18% of $62,055, the Census ACS 2022 median household income for Arizona, divided across twelve months, 2% 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 Arizona's one-child starting rate sits
Each bar counts states with a published one-child base rate in that 3-point guideline band. Arizona is marked in its own band. Counts are exact from the 51-jurisdiction dataset.
Arizona'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.

Dense order-establishment share
Arizona in the denser-order third
Arizona sits in the top third on OCSE P-64 order share (92.7% · #8 of 51).
Arizona posts 92.7% of its Title IV-D caseload with an established order - denser than two-thirds of reporting jurisdictions on OCSE P-64. 43 jurisdictions share the Income Shares model with Arizona. Unlike capped states, the formula applies to full reported income before deductions. Nearest one-child rate peer: Alabama at 18% (Δ 0.0 pts). Arizona 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 Arizona to other guideline models →
On OCSE FY2023 tables, Arizona ranks #8 of 51 on order-establishment share and #30 by caseload volume (~$2,183 distributed per case, our calc on P-4/P-52). Source: HHS Office of Child Support Services, FY 2023 Preliminary Report.
How Arizona Calculates Child Support
Arizona 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 Arizona's denser-than-most order-establishment share when reading enforcement.
