[Excerpt] From 1980 to 2013, the percentage of Connecticut residents living in neighborhoods of concentrated wealth or poverty grew by 30 percent, according to a new analysis from DataHaven.

Meanwhile, the percentage of residents living in middle-income neighborhoods shrunk 7 percent.
 
These trends show that income inequality is a chronic issue — and that the polarization of Connecticut neighborhoods is growing. Studies show that this concentration of wealth and poverty causes several negative outcomes. Among them are poor health and high crime in areas of extreme poverty, and the concentration of regional resources in very affluent neighborhoods for richer residents.
 
Additionally, our recently published analysis that compared Connecticut to a national study of racially concentrated affluence showed that Connecticut faces racial segregation along income lines that in many ways surpass those of other large metropolitan areas.
