“In St. Louis, ZIP codes matter,” says Piergiorgio Castotti, an Italian photographer who lived in the US for three years. “North of Delmar boulevard, 95% of people are black, and life expectancy is 67. A few hundred yards south, 70% of people are white, and there is a life expectancy of 82.”
Index G, a collaborative project he’s made with photographer Emanuele Brutti, explores the harsh reality of this segregation, which is measured with the so-called Gini Index. Where once racial segregation in the US was obvious, and even enshrined in law, it’s now peppered throughout cities on a micro level, from neighbourhood to neighbourhood, and can therefore be easy to miss. “There were unexpectedly very few literal barriers in St. Louis; this meant that our first trip was a disaster,” says Castotti. “I didn’t know what to take pictures of.”
