Since the Supreme Court reinstated the punishment in the mid-1970s, more than 1,300 people have been executed, according to Death Penalty Information Center data displayed in the above Pew Research Center animation. All but three were executed in state prisons. More than a third of all executions have taken place in Texas. Just six states — Texas, Virginia, Oklahoma, Florida, Missouri and Alabama — accounted for two-thirds of all executions. Eighteen states lack the death penalty, as shown in the below graphic.
The number of annual executions peaked in 1999, when 98 people were killed. The number of exonerations peaked a few years later, in 2003, when 12 prisoners were cleared of their crimes.
Support for the death penalty swelled from the mid-1960s to mid-1990s, but has since seen a steep decline, according to Pew. Support still outweighs opposition among all age groups, both genders, and by education. The demographic groups in which opposition is stronger are: Democrats, Hispanics and blacks.
