NCRP also known as the National corrections Reporting Program is the main data base that the information is reported to. It collects information from intake to releases. When it comes to prison population it has grown significantly over the last decade. The corrections industry estimates to be a 5.4-billion-dollar industry in the prisons themselves. These costs include bailouts, court fees, and even phone privileges. The main goal for Prison is to be able to rehabilitate the offenders. Another goal is to be there for retribution and deterrence. The current incarceration rate in the United States 2.3 million people as of 2016. As a breakdown the rate is 655 people per 100,000. United States only makes up about 5% of the world population, but we account for 25% of the world population of incarcerations. We also lead the most imprisoners in the world. In 2014, a report from the National research council examined that the two main causes of the issue are due to prison sentences being increased, and the increase of crime in populations.
