Southwestern Cusd 9 operates 5 public schools serving 1,210 students, placing it among the smallest districts in Illinois. The school portfolio breaks down into 2 elementary, 1 high, 1 combined, 1 middle schools, a small enough portfolio that most families will interact with nearly every campus in the district at some point. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Macoupin County.
Per-pupil expenditure runs $13,941 according to the NCES F-33 School District Finance Survey, in the lower half of 848 Illinois districts by per-pupil spending.

That dominant concentration means Southwestern Cusd 9-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
