Regardless of where you live or work or who you’re friends with, you usually move around the same neighbourhoods and streets of your city. It may be London, Santiago, Shanghai, or Moscow, but in any of these places, there are always districts you have never set a foot in. Have you ever considered how many ‘cities’ are within your own city?
A research article published in The Royal Society Open Science and signed by Chilean researchers utilizes big data to analyze and visualize urban segregation, delivering spatial tools that allow us to develop strategies in a city of many cities. "We know there are [social] bubbles in Santiago, Chile, and that therefore, there is segregation," says Teodoro Dannemann, co-author of the research paper The time geography of segregation during working hours, in a conversation with ArchDaily. “We know that each person explores only a small fraction of the city, which is basically the home-work trajectory. This implies that we only engage with a small group of citizens," he adds.
