National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Marana has more public-school enrollment than 44% of the 4,487 US cities in this directory. Marana sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
Combined-grade campuses shape the local portfolio
6 of Marana's 10 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
A small portfolio contains radically different campus scales
Marana lists only 10 schools, yet reported enrollment runs from 1 to 1,004 students, a 1004-fold range. In a portfolio this compact, the smallest record may be a specialized or nonstandard setting rather than a miniature version of the largest campus. That distinction affects how ratios and program fields should be read. Compare similarly configured grade levels first; combining the extremes into one city average conceals more than it explains.
