The Death Penalty Information Center (DPI) is a national non-profit organization providing the media, policymakers, and the general public with data and analysis on issues concerning capital punishment and the people it affects. For more than 30 years, DPI has been the preeminent national resource for timely and trustworthy information about the death penalty. DPI does not take a position on the death penalty itself but is critical of problems in its application.
Founded in 1990, DPI promotes insightful discourse on the death penalty by curating and presenting expansive, authoritative data from credible sources and offering clear, reliable, and timely information and research about the history and current application of the death penalty. DPI’s careful tracking and analysis of death sentences, executions, legislation, and newsworthy events provides critical context to inform meaningful public debate and sound policy decisions.
