"• As of 2016, an estimated 6.1 million people are disenfranchised due to a felony conviction, a figure that has escalated dramatically in recent decades as the population under criminal justice supervision has increased. There were an estimated 1.17 million people disenfranchised in 1976, 3.34 million in 1996, and 5.85 million in 2010.
"• Approximately 2.5 percent of the total U.S. voting age population – 1 of every 40 adults – is disenfranchised due to a current or previous felony conviction.
"• Individuals who have completed their sentences in the twelve states that disenfranchise people post-sentence make up over 50 percent of the entire disenfranchised population, totaling almost 3.1 million people."
