National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Carbondale has more public-school enrollment than 8% of the 4,487 US cities in this directory. Carbondale 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.
The school portfolio is elementary-weighted
3 of Carbondale's 6 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 0 middle and 2 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
Governance mix is central to a fair comparison
2 of 6 listed Carbondale campuses are reported as charters, so district-run and charter records occupy substantial shares of the same city view. They may follow different governance, enrollment, and program structures even when their mailing city matches. The 29-point gap between Bridges and Roaring Fork High School should be read within that context, not as a single-system league table. Check charter status and district affiliation before comparing two nearby schools, and verify current admissions rules with the operator.
