Every Execution in U.S. History in a Single Map

Updated December 16, 2015.

Before his lethal injection was delayed at the eleventh hour by a federal appeals court Tuesday, Robert James Campbell was scheduled to become the 1,231st person to be executed by Texas since it joined the Union in 1845.

As Josh Sanburn writes in the magazine this week, capital punishment in the United States is at a crossroads as some states are having a difficult time finding the chemicals required for lethal injections.

The map above shows every legal execution by a state since 1776. Drag the red triangle to view the data at any point in time, or hit play to watch the map animate. Shrewd readers will note that the total figure in the lower righthand corner is significantly lower than the total in TIME’s chart of executions by method. This map only shows executions administered at the state level, not those implemented by the federal government or the military. Michigan, for example, has never executed someone since attaining statehood, but was the site to one federal execution.

Data for historical executions through 1976 are derived from research conducted by M. Watt Espy and John Ortiz Smykla. Data since the end of the hiatus come from the Death Penalty Information Center.
