From the Washington Post, where the graphic resides:
A majority of Americans support the death penalty, but their ranks have been shrinking for 17 years, according to a new Pew Research Center poll.
As of 2013, 55 percent of adults say they back the death penalty for convicted murderers, while 37 percent say they do not. That’s a sizable difference from two years earlier, when support won out with 62 percent with 31 percent opposed. A majority of whites, Republicans and independents support the death penalty, while majorities of Hispanics, blacks and Democrats do not.
