At a cost of nearly $1 billion annually, more than 17,000 people are caged every night in county jails and city lockups. But not every neighborhood is equally impacted by L.A.’s massive jail system. In fact, L.A.’s nearly billion-dollar jail budget is largely committed to incarcerating many people from just a few neighborhoods. In some communities, local authorities are spending more than one-million dollars annually to lock up residents. These are L.A.’s Million Dollar Hoods. Visit milliondollarhoods.org to view the Map Room, which shows the neighborhoods where persons arrested by LASD and LAPD live and how much LAPD and/or LASD spent to incarcerate them.
