I live in a school district in Brooklyn that has been in the news because of gentrification and increasing segregation within the schools. To look more closely at the situation I looked at data collected by public and charter schools in District 13 over the 14 years since the first charter school opened in Brooklyn.
Source: census data from 2000 decennial census and American Community Survey data from 2013, NYC building foot prints.
Screenshot from an interactive component. Each circle shows decline or growth of student enrollment over the last 10 years.
This interactive map uses the building footprints to show school co-locations. Demographic and enrollment data can be viewed by clicking the school.
