In the study, “Life Goes On: The Historic Rise in Life Imprisonment in the United States,” Nellis and her coauthors examined the trends in the population of prisoners serving life sentences with and without parole. In 2012, many prisons across the nation closed, but the amount of people serving life sentences continued to grow. Nellis and her coauthors used state department census to complete the report. The authors also used survey data from people serving life sentences from all 50 states and the Federal Bureau of Prisons in 2012. This data included demographic characteristics, offense types and other long-term trends in the life-sentenced population.
