See the rise and fall of methods of capital punishment since 1700—from hanging to burning to lethal injection, including Tuesday's botched execution in Oklahoma
Mouse over or tap a bar in the chart to see the figures for that year.
How states have executed prisoners has changed over time. More than half of the 15,717 executions in U.S. history have been by hanging. Today, lethal injection has replaced electrocution as the dominant method of capital punishment in the United States. Tuesday’s failure in Oklahoma is not the first time the method has failed to quickly kill a convict. (There were no executions from 1967 to 1977. They resumed following a Supreme Court ruling.)
