An interactive map application allows us to see how cities have changed over time with respect to segregation/integration. Graham MacDonald of The Atlantic compiled maps for 268 Metro areas from the work done by Sophie Litschwartz. The maps show the changes from 1970 to 2010 and take the dissimilarity index created by Litschwartz and apply it to the map. The dissimilarity index demonstrates how segregated or integrated a city is through a number between 0 and 100. 100 being totally segregated.
