Big cities are an exception to this as it is not possible to segment further. Examples, such as Chicago or Buffalo New York come to mind where some of the best and worst schools in America exist in the same school district. Opening the avenues between these schools is often met with strong opposition, often from the underprivileged minority groups that would most benefit. Programs that reach out to the community as a whole but fail to represent that community's racial statistics are such targets. When I was a kid our school admissions was on a lottery system where 70% of the school was admitted, but due to low parent involvement African Americans were made up a few dozen percentage points lower in neighboring schools. They made a majority although not a super-majority. I wondered what the so-called 'community leaders' that would protest this state of affairs hand in mind for the 40% of their skin color.
