Noted: MARS was the brainchild of Matthew Desmond, a Harvard sociologist whose recent book, “Evicted: Poverty and Profit in the American City,” brought national attention to evictions. The book chronicles the lives of several poor families living in a variety of housing situations, such as crime-ridden inner-city neighborhoods and blighted trailer parks. To supplement his on-the-ground work in these communities, Desmond went searching for data. First, he looked at court records to gather eviction statistics, but there were lots of questions that those records couldn’t answer, such as what are the demographics of people facing eviction. Then he looked at the academic literature, but that search “came up empty,” Desmond said. That’s when he reached out to the University of Wisconsin Survey Center, an academic research organization that specializes in reaching understudied groups: kids in foster care, welfare recipients, the homeless.
