Johnson is coordinating the visits between residents as part of the project. She photographed each “map twin” at his or her home, and from there residents are visiting or are planning to visit each other’s homes. Conversations are somewhat guided as Johnson developed a set of questions — ranging from how much they paid for their home to how they would describe their neighborhood — with the help of the journalism lab City Bureau, where she was a fellow, and later Loyola University Chicago. In the fall, Johnson wants to host a dinner to bring everyone together.
