A project that includes prison expenditure maps to examine changes in the way money is invested in communities. Chang worked on this project in 2005-2007 in New Orleans as part of a fellowship with the Spatial Information Design Lab. More than 2 million people are in jails and prisons in the U.S., and Louisiana has the highest incarceration rate in the world. In many places the concentration is so dense that the government spends over a million dollars per year to imprison residents of a single city block. At the same time, communities are continuously struggling to receive funding for civic services like youth programs, job training, and peer support that would provide more opportunities for residents and prevent a life towards crime. These maps provide the case that money is available if used in better ways. They worked with a justice reinvestment network of local organizations, including Cafe Reconcile, Safe Streets/Strong Communities and the Juvenile Justice Project of Louisiana, to help establish local pilot projects for job training, health services, and mentorship programs supported by justice reinvestment funding.
