EdBuild, a nonprofit focused on equity in school funding, defines an isolating border as one that divides one school district from another that is at least 25 percent whiter and receives at least 10 percent more funding per student. Across the United States, in 42 states, there are 969 of these isolating borders, according to EdBuild’s recently released report. The average disparity in funding along these borders was roughly $4,000 per student.  As a report from the Lincoln Institute of Land Policy shows, roughly 36 percent of K–12 funding comes from these [local property] taxes. That means inequality is often baked into district lines; wealthier communities will have more money to spend on their students.
