It’s amazing how geography professor Kyle Walker has been able to visualize city populations like the image below. The color coded dots in this case relate to how much education the residents in those areas received growing up.
Blue dots are graduate degrees, green are bachelor’s, yellow are some college, orange are high school, and red is everything short of high school.
Unfortunately, the clear divide in education across boroughs in New York City is evident in most of the thirteen city maps shown in this link. I recommend scrolling through them as they are fascinating to see and send a message that is hard to ignore.
