Iowa has 327 school districts reporting chronic absenteeism data. Five of them account for more than a quarter of every chronically absent student in the state.

Des Moines Independent^↗ET (6,306 chronically absent), Davenport^↗ET (4,284), Cedar Rapids^↗ET (4,208), Waterloo^↗ET (3,562), and Sioux City^↗ET (2,441) combine for 20,801 chronically absent students — 27.2% of the state's total of 76,535. These five districts enroll 17.1% of Iowa's students but produce 27.2% of its chronic absence. They punch 1.6 times above their enrollment weight.

The math of targeted intervention

If Iowa reduced chronic absenteeism in just these five districts to the statewide average of 15.8%, the state's total chronically absent population would drop by roughly 7,600 students — a 10% reduction in the state total from interventions in 1.5% of districts.

This is the concentration advantage: in a state with hundreds of districts, the chronic absence problem is concentrated enough that meaningful progress does not require 327 separate strategies. It requires five very good ones.

The challenge is that each of these five districts has a different version of the problem. Des Moines' 21.2% rate is elevated but improving fast. Waterloo's 33.5% and Davenport's 33.2% are double the state average and declining slowly. Cedar Rapids sits at 27.8%, and Sioux City at 16.9% — barely above the state average and arguably not a crisis district at all.

Sioux City: the exception in the top five

Sioux City's inclusion in the top five is a function of size, not rate. At 16.9%, its chronic rate is only 1.1 points above the state average. The district makes the list because it enrolls 14,470 students — enough that even a near-average rate produces 2,441 chronically absent students.

This illustrates a tension in attendance policy. Should intervention resources flow to the districts with the highest rates (Waterloo at 33.5%) or the highest counts (Des Moines at 6,306)? The rate-focused approach targets the worst-performing systems. The count-focused approach maximizes the number of students reached.

Concentration has been stable

The top-five share of Iowa's chronically absent population has hovered around 25-28% for most of the nine-year dataset. It dipped slightly during the COVID peak, when chronic absence became so widespread that small and mid-sized districts contributed a larger share. In 2024-25, with the statewide rate falling, the concentration rose slightly as the five largest districts improved at somewhat different paces than the rest of the state.

Des Moines alone accounts for 8.2% of all chronically absent students in Iowa — one in twelve — from a district that enrolls 6.1% of the state. If Des Moines' rate were at the state average, the district would have 4,693 chronically absent students instead of 6,306, and the state total would drop by 1,613.

Beyond the top five

The concentration extends beyond the top five. The top ten districts account for approximately 37% of all chronically absent students. The top twenty account for roughly half. Iowa's 307 remaining districts — home to more than 300,000 students — account for the other half.

This distribution has implications for state policy. SF 2435's uniform requirements — certified mail, engagement meetings, truancy designations — apply the same way in a district of 200 students and a district of 30,000. The operational burden of certified mail in Des Moines ($70,000 in postage) is qualitatively different from the same requirement in a district where the superintendent knows every family.

The most efficient path to a lower statewide rate runs through a small number of large buildings in five cities. The political and operational barriers to that approach are another matter.
