The majority of Americans, 55%, are in favor of the death penalty for convicted murderers in the U.S. While this marks the sixth consecutive year that support for capital punishment is between 54% and 56%, it is below the 60% to 80% readings recorded in the four prior decades between 1976 and 2016.When Gallup initiated this measure in 1936, 59% of U.S. adults favored the death penalty for convicted murderers -- and majorities have supported it since then, with the exception of several readings taken between 1957 and March 1972, including the record-low 42% in 1966.
After the U.S. Supreme Court ruled the death penalty unconstitutional in June 1972, majorities continued to back it. When it was reinstated in 1976, public support for it grew until it peaked at 80% in 1994. At least 60% of U.S. adults favored capital punishment until 2017, when support dipped to the lowest point since 1972, and today it remains at that level.
