According to a 2013 Pew Research Center survey, 55% of U.S. adults say they favor the death penalty for persons convicted of murder. A significant minority (37%) oppose the practice.
While a majority of U.S. adults still support the death penalty, public opinion in favor of capital punishment has seen a modest decline since November 2011, the last time Pew Research asked the question. In 2011, fully six-in-ten U.S. adults (62%) favored the death penalty for murder convictions, and 31% opposed it.
Public support for capital punishment has ebbed and flowed over time, as indicated by polls going all the way back to the 1930s. But it has been gradually ticking downward for the past two decades, since Pew Research began collecting survey data on this issue.1 Since 1996, the margin between those who favor the death penalty and those who oppose it has narrowed from a 60-point gap (78% favor vs. 18% oppose) to an 18-point difference in 2013 (55% favor vs. 37% oppose). …
Twice as many white Americans favor the death penalty as oppose it (63% vs. 30%). Among black adults, the balance of opinion is reversed: 55% oppose capital punishment, while 36% support it. The margin is narrower among Hispanics, but more oppose the death penalty (50%) than support it (40%).
Even among white adults, support for capital punishment has decreased markedly over the past two decades, from 81% in 1996 to 63% in 2013.
