You may not know your neighbors by name, but you can at least know them by education level.
Kyle Walker, an assistant professor of geography at Texas Christian University, has created an interactive dot map visualizing US neighborhoods by educational attainment.
Each dot represents between 25-500 people over the age of 25, and each is color-coded based on how far those people have gone in school. 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.
The map helps to solidify what are, for most people, likely abstract concepts. They confirm people with less education tend to live in the outer boroughs around Manhattan, for example, and that a single highway can separate rich and poor.
Here’s how the maps shake out in various cities across the US.
The San Francisco Bay Area is marked by high levels of education in Berkeley gradually shifting to less education further south in Oakland. Across the Bay, San Francisco is made up largely of graduate degrees — except for a pocket of red in Chinatown.
New York City residents cluster blue in Manhattan and affluent parts of Brooklyn but get less educated deeper into the outer boroughs. On the island, blue dots begin to fade into green and yellow near 100th St., as it turns into Harlem.
