The document discusses the costs and benefits of electronic monitoring (EM) as an alternative to incarceration in Michigan prisons. It notes that over $1.5 billion is spent annually to incarcerate 44,113 people at a cost of $33,822 per prisoner. In contrast, EM costs only $2,362 annually per person monitored. EM could help reduce prison overcrowding and save taxpayers money while allowing offenders to maintain employment and family ties.
