Left bar is the racial makeup of LaSalle County residents (Census ACS 5-year). Right bar is the enrollment-weighted makeup of public schools in the county (NCES CCD). NCES systematically under-reports Hispanic, Pacific Islander, and Native American enrollment for many schools; where the resident share is meaningful but the reported school share is zero, we mark the school bar "not reported".
