Quizplus · Accepted Answer

The graying of America's prison population is primarily due to factors such as the implementation of three-strikes and truth-in-sentencing laws, which lead to longer prison sentences; the general aging of the American population; and the prison-building boom of the 1980s and 1990s, which increased incarceration rates.
