Go look at the schools in poor Black neighborhoods in Cleveland, Chicago, Boston, Columbus, Detroit, Indianapolis, Cincinnatti. You will find buildings in disrepair, lacking basic things like air conditioning. Last year, Columbus City Schools cancelled classes several days because it was too hot. If you look at teachers' salaries, the city school districts pay significantly less than the surrounding suburbs, while having higher student/teacher ratios and a disproportionate number of students with Individualized Education Plans, that are English-learners, or that have other unique challenges to overcome. Standardized testing shows these schools, as one migh expect, have far poorer learning outcomes for their students, as well.

I can't tell you why your numbers appear to show otherwise, but anyone can easily verify that there is an enormous disparity between the quality of schools attended by residents of poor--often mostly Black--school districts and that attended by residents of wealthier--typically whiter--school districts.
