How many prisons built in America since 1965?

Since 1965, more than 1,200 new prisons have been built in the United States. This surge in prison construction reflects a significant increase in incarceration rates and changes in criminal justice policies, particularly during the 1980s and 1990s. Many of these facilities were built to accommodate the growing populations in the criminal justice system. The trend has raised concerns about over-incarceration and its social implications.
