Branches in areas that are more financially distressed are more likely to be closed by 6 p.m. on weekdays and completely on weekends. Libraries in communities with low poverty rates are more likely to stay open until 8 p.m., and be open on weekends. In addition, across the city, branches experience unanticipated closures due to staffing shortages, with the poorest neighborhoods - North, Northeast, Southwest and North Central - accounting for more than half of the 372 closures so far this year.
