The Economist maps out every American execution since 1976, when the Supreme Court announced the modern constitutional regime governing death penalty cases after effectively suspending all executions nationwide for four years. Over one-third of all executions during this period took place in Texas, for a total of 481 people killed by that state. Of the remaining, non-Texas executions, the overwhelming majority are clustered in a small group of southern states:
It’s worth noting that, although the death penalty is still technically legal in most states, actual executions are very rare in most of the country — even after a person has been sentenced to death row. According to a 2011 study by the Death Penalty Information Center, thirty-two U.S. jurisdictions executed no one in the previous five years and more than half of those jurisdictions executed no one after the Supreme Court permitted executions to continue in 1976. Only 12 states executed someone in 2010, and only 7 states executed more than one person.
