Mass Incarceration and Prison Overcrowding in the United States
The United States experienced unprecedented growth in its prison population from 1970 onwards, driven by policy changes including stricter sentencing laws and the War on Drugs. This expansion created severe overcrowding in prisons nationwide, peaking in 2009 before declining marginally.
Why It Matters
Prison overcrowding has compromised the justice system's ability to provide adequate rehabilitation, services, and humane conditions for incarcerated individuals, disproportionately affecting communities of color and raising fundamental questions about the effectiveness and equity of the criminal justice system.
