The New York Times has created a series of visualizations examining the effect poor children’s cross-class friendships have on their income rank as adults. One visualization displays each zip code in the United States as a dot. Zip codes with a lower prevalence of cross-class friendships appear as red dots and those with a higher prevalence appear as green dots. The visualization then places each dot on a graph showing average adult income rank. According to the visualization, poor children with more cross-class friendships are more likely to earn a high income as an adult.
