The use of the death penalty is gradually disappearing in the United States. Last year, in part because of the coronavirus outbreak, fewer people were executed than in any year in nearly three decades.

Yet the death penalty for people convicted of murder continues to draw support from a majority of Americans despite widespread doubts about its administration, fairness and whether it deters serious crimes.

More Americans favor than oppose the death penalty: 60% of U.S. adults favor the death penalty for people convicted of murder, including 27% who strongly favor it. About four-in-ten (39%) oppose the death penalty, with 15% strongly opposed, according to a new Pew Research Center survey.

The survey, conducted April 5-11 among 5,109 U.S. adults on the Center’s American Trends Panel, finds that support for the death penalty is 5 percentage points lower than it was in August 2020, when 65% said they favored the death penalty for people convicted of murder.

While public support for the death penalty has changed only modestly in recent years, support for the death penalty declined substantially between the late 1990s and the 2010s. (See “Death penalty draws more Americans’ support online than in telephone surveys” for more on long-term measures and the challenge of comparing views across different survey modes.)

Large shares of Americans express concerns over how the death penalty is administered and are skeptical about whether it deters people from committing serious crimes.

Nearly eight-in-ten (78%) say there is some risk that an innocent person will be put to death, while only 21% think there are adequate safeguards in place to prevent that from happening. Only 30% of death penalty supporters – and just 6% of opponents – say adequate safeguards exist to prevent innocent people from being executed.

A majority of Americans (56%) say Black people are more likely than White people to be sentenced to the death penalty for being convicted of serious crimes. This view is particularly widespread among Black adults: 85% of Black adults say Black people are more likely than Whites to receive the death penalty for being convicted of similar crimes (61% of Hispanic adults and 49% of White adults say this).

Moreover, more than six-in-ten Americans (63%), including about half of death penalty supporters (48%), say the death penalty does not deter people from committing serious crimes.

Yet support for the death penalty is strongly associated with a belief that when someone commits murder, the death penalty is morally justified. Among the public overall, 64% say the death penalty is morally justified in cases of murder, while 33% say it is not justified. An overwhelming share of death penalty supporters (90%) say it is morally justified under such circumstances, compared with 25% of death penalty opponents.

Partisanship continues to be a major factor in support for the death penalty and opinions about its administration. Just over three-quarters of Republicans and independents who lean toward the Republican Party (77%) say they favor the death penalty for persons convicted of murder, including 40% who strongly favor it.

Democrats and Democratic leaners are more divided on this issue: 46% favor the death penalty, while 53% are opposed. About a quarter of Democrats (23%) strongly oppose the death penalty, compared with 17% who strongly favor it.

Over the past two years, the share of Republicans who say they favor the death penalty for persons convicted of murder has decreased slightly – by 7 percentage points – while the share of Democrats who say this is essentially unchanged (46% today vs. 49% in 2019).

Republicans and Democrats also differ over whether the death penalty is morally justified, whether it acts as a deterrent to serious crime and whether adequate safeguards exist to ensure that no innocent person is put to death. Republicans are 29 percentage points more likely than Democrats to say the death penalty is morally justified, 28 points more likely to say it deters serious crimes, and 19 points more likely to say that adequate safeguards exist.

But the widest partisan divide – wider than differences in opinions about the death penalty itself – is over whether White people and Black people are equally likely to be sentenced to the death penalty for committing similar crimes.

About seven-in-ten Republicans (72%) say that White people and Black people are equally likely to be sentenced to death for the same types of crimes. Only 15% of Democrats say this. More than eight-in-ten Democrats (83%) instead say that Black people are more likely than White people to be sentenced to the death penalty for committing similar crimes.

Differing views of death penalty by race and ethnicity, education, ideology

There are wide ideological differences within both parties on this issue. Among Democrats, a 55% majority of conservatives and moderates favor the death penalty, a position held by just 36% of liberal Democrats (64% of liberal Democrats oppose the death penalty). A third of liberal Democrats strongly oppose the death penalty, compared with just 14% of conservatives and moderates.

While conservative Republicans are more likely to express support for the death penalty than moderate and liberal Republicans, clear majorities of both groups favor the death penalty (82% of conservative Republicans and 68% of moderate and liberal Republicans).

As in the past, support for the death penalty differs across racial and ethnic groups. Majorities of White (63%), Asian (63%) and Hispanic adults (56%) favor the death penalty for persons convicted of murder. Black adults are evenly divided: 49% favor the death penalty, while an identical share oppose it.

Support for the death penalty also varies across age groups. About half of those ages 18 to 29 (51%) favor the death penalty, compared with about six-in-ten adults ages 30 to 49 (58%) and those 65 and older (60%). Adults ages 50 to 64 are most supportive of the death penalty, with 69% in favor.

There are differences in attitudes by education, as well. Nearly seven-in-ten adults (68%) who have not attended college favor the death penalty, as do 63% of those who have some college experience but no degree.

About half of those with four-year undergraduate degrees but no postgraduate experience (49%) support the death penalty. Among those with postgraduate degrees, a larger share say they oppose (55%) than favor (44%) the death penalty.

The divide in support for the death penalty between those with and without college degrees is seen across racial and ethnic groups, though the size of this gap varies. A large majority of White adults without college degrees (72%) favor the death penalty, compared with about half (47%) of White adults who have degrees. Among Black adults, 53% of those without college degrees favor the death penalty, compared with 34% of those with college degrees. And while a majority of Hispanic adults without college degrees (58%) say they favor the death penalty, a smaller share (47%) of those with college degrees say this.

Intraparty differences in support for the death penalty

Republicans are consistently more likely than Democrats to favor the death penalty, though there are divisions within each party by age as well as by race and ethnicity.

Republicans ages 18 to 34 are less likely than other Republicans to say they favor the death penalty. Just over six-in-ten Republicans in this age group (64%) say this, compared with about eight-in-ten Republicans ages 35 and older.

Among Democrats, adults ages 50 to 64 are much more likely than adults in other age groups to favor the death penalty. A 58% majority of 50- to 64-year-old Democrats favor the death penalty, compared with 47% of those ages 35 to 49 and about four-in-ten Democrats who are 18 to 34 or 65 and older.

Overall, White adults are more likely to favor the death penalty than Black or Hispanic adults, while White and Asian American adults are equally likely to favor the death penalty. However, White Democrats are less likely to favor the death penalty than Black, Hispanic or Asian Democrats. About half of Hispanic (53%), Asian (53%) and Black (48%) Democrats favor the death penalty, compared with 42% of White Democrats.

About eight-in-ten White Republicans favor the death penalty, as do about seven-in-ten Hispanic Republicans (69%).

Differences by race and ethnicity, education over whether there are racial disparities in death penalty sentencing

There are substantial demographic differences in views of whether death sentencing is applied fairly across racial groups. While 85% of Black adults say Black people are more likely than White people to be sentenced to death for committing similar crimes, a narrower majority of Hispanic adults (61%) and about half of White adults (49%) say the same. People with four-year college degrees (68%) also are more likely than those who have not completed college (50%) to say that Black people and White people are treated differently when it comes to the death penalty.

About eight-in-ten Democrats (83%), including fully 94% of liberal Democrats and three-quarters of conservative and moderate Democrats, say Black people are more likely than White people to be sentenced to death for committing the same type of crime – a view shared by just 25% of Republicans (18% of conservative Republicans and 38% of moderate and liberal Republicans).

Across educational and racial or ethnic groups, majorities say that the death penalty does not deter serious crimes, although there are differences in how widely this view is held. About seven-in-ten (69%) of those with college degrees say this, as do about six-in-ten (59%) of those without college degrees. About seven-in-ten Black adults (72%) and narrower majorities of White (62%) and Hispanic (63%) adults say the same. Asian American adults are more divided, with half saying the death penalty deters serious crimes and a similar share (49%) saying it does not.

Among Republicans, a narrow majority of conservative Republicans (56%) say the death penalty does deter serious crimes, while a similar share of moderate and liberal Republicans (57%) say it does not.

A large majority of liberal Democrats (82%) and a smaller, though still substantial, majority of conservative and moderate Democrats (70%) say the death penalty does not deter serious crimes. But Democrats are divided over whether the death penalty is morally justified. A majority of conservative and moderate Democrats (57%) say that a death sentence is morally justified when someone commits a crime like murder, compared with fewer than half of liberal Democrats (44%).

There is widespread agreement on one topic related to the death penalty: Nearly eight-in-ten (78%) say that there is some risk an innocent person will be put to death, including large majorities among various racial or ethnic, educational, and even ideological groups. For example, about two-thirds of conservative Republicans (65%) say this – compared with 34% who say there are adequate safeguards to ensure that no innocent person will be executed – despite conservative Republicans expressing quite favorable attitudes toward the death penalty on other questions.

Overwhelming share of death penalty supporters say it is morally justified

Those who favor the death penalty consistently express more favorable attitudes regarding specific aspects of the death penalty than those who oppose it.

For instance, nine-in-ten of those who favor the death penalty also say that the death penalty is morally justified when someone commits a crime like murder. Just 25% of those who oppose the death penalty say it is morally justified.

This relationship holds among members of each party. Among Republicans and Republican leaners who favor the death penalty, 94% say it is morally justified; 86% of Democrats and Democratic leaners who favor the death penalty also say this.

By comparison, just 35% of Republicans and 21% of Democrats who oppose the death penalty say it is morally justified.

Similarly, those who favor the death penalty are more likely to say it deters people from committing serious crimes. Half of those who favor the death penalty say this, compared with 13% of those who oppose it. And even though large majorities of both groups say there is some risk an innocent person will be put to death, members of the public who favor the death penalty are 24 percentage points more likely to say that there are adequate safeguards to prevent this than Americans who oppose the death penalty.

On the question of whether Black people and White people are equally likely to be sentenced to death for committing similar crimes, partisanship is more strongly associated with these views than one’s overall support for the death penalty: Republicans who oppose the death penalty are more likely than Democrats who favor it to say White people and Black people are equally likely to be sentenced to death.

Among Republicans who favor the death penalty, 78% say that Black and White people are equally likely to receive this sentence. Among Republicans who oppose the death penalty, about half (53%) say this. However, just 26% of Democrats who favor the death penalty say that Black and White people are equally likely to receive this sentence, and only 6% of Democrats who oppose the death penalty say this.

CORRECTION (July 13, 2021): The following sentence was updated to reflect the correct timespan: “Last year, in part because of the coronavirus outbreak, fewer people were executed than in any year in nearly three decades.” The changes did not affect the report’s substantive findings.

The American Trends Panel survey methodology

Overview

The American Trends Panel (ATP), created by Pew Research Center, is a nationally representative panel of randomly selected U.S. adults. Panelists participate via self-administered web surveys. Panelists who do not have internet access at home are provided with a tablet and wireless internet connection. Interviews are conducted in both English and Spanish. The panel is being managed by Ipsos.

Data in this report is drawn from the panel wave conducted April 5 to 11, 2021, and included oversamples of Asian, Black and Hispanic Americans. A total of 5,109 panelists responded out of 5,970 who were sampled, for a response rate of 86%. This does not include two panelists who were removed from the data due to extremely high rates of refusal or straightlining. The cumulative response rate accounting for nonresponse to the recruitment surveys and attrition is 4%. The break-off rate among panelists who logged on to the survey and completed at least one item is 2%. The margin of sampling error for the full sample of 5,109 respondents is plus or minus 2.1 percentage points.

Panel recruitment

The ATP was created in 2014, with the first cohort of panelists invited to join the panel at the end of a large, national, landline and cellphone random-digit-dial survey that was conducted in both English and Spanish. Two additional recruitments were conducted using the same method in 2015 and 2017, respectively. Across these three surveys, a total of 19,718 adults were invited to join the ATP, of whom 9,942 (50%) agreed to participate.

In August 2018, the ATP switched from telephone to address-based recruitment. Invitations were sent to a random, address-based sample of households selected from the U.S. Postal Service’s Delivery Sequence File. Two additional recruitments were conducted using the same method in 2019 and 2020, respectively. Across these three address-based recruitments, a total of 17,161 adults were invited to join the ATP, of whom 15,134 (88%) agreed to join the panel and completed an initial profile survey. In each household, the adult with the next birthday was asked to go online to complete a survey, at the end of which they were invited to join the panel. Of the 25,076 individuals who have ever joined the ATP, 13,537 remained active panelists and continued to receive survey invitations at the time this survey was conducted.

The U.S. Postal Service’s Delivery Sequence File has been estimated to cover as much as 98% of the population, although some studies suggest that the coverage could be in the low 90% range.¹ The American Trends Panel never uses breakout routers or chains that direct respondents to additional surveys.

Sample design

The overall target population for this survey was non-institutionalized persons ages 18 and older, living in the U.S., including Alaska and Hawaii.

This study featured a stratified random sample from the ATP. The sample was allocated according to the following strata, in order: Asian Americans (including those who identify as Asian in combination with another race), Black Americans (including those who identify as Black in combination with another race), U.S.-born Hispanics, foreign-born Hispanics, tablet households,  high school education or less, not registered to vote, people ages 18 to 34, uses internet weekly or less, nonvolunteers, and all other categories not already falling into any of the above.

The Asian, Black, U.S.-born and foreign-born Hispanic strata were oversampled relative to their share of the U.S. adult population. The remaining strata were sampled at rates designed to ensure that the share of respondents in each stratum is proportional to its share of the U.S. adult population to the greatest extent possible. Respondent weights are adjusted to account for differential probabilities of selection as described in the Weighting section below.

Questionnaire development and testing

The questionnaire was developed by Pew Research Center in consultation with Ipsos. The web program was rigorously tested on both PC and mobile devices by the Ipsos project management team and Pew Research Center researchers. The Ipsos project management team also populated test data which was analyzed in SPSS to ensure the logic and randomizations were working as intended before launching the survey.

Incentives

All respondents were offered a post-paid incentive for their participation. Respondents could choose to receive the post-paid incentive in the form of a check or a gift code to Amazon.com or could choose to decline the incentive. Incentive amounts ranged from $5 to $20 depending on whether the respondent belongs to a part of the population that is harder or easier to reach. Differential incentive amounts were designed to increase panel survey participation among groups that traditionally have low survey response propensities.

Data collection protocol

The data collection field period for this survey was April 5 to 11, 2021. Postcard notifications were mailed to all ATP panelists with a known residential address on April 5, 2021. 

On April 5 and April 6, invitations were sent out in two separate launches: Soft launch and full launch. Sixty panelists were included in the soft launch, which began with an initial invitation sent on April 5, 2021. The ATP panelists chosen for the initial soft launch were known responders who had completed previous ATP surveys within one day of receiving their invitation. All remaining English- and Spanish-speaking panelists were included in the full launch and were sent an invitation on April 6, 2021.

All panelists with an email address received an email invitation and up to two email reminders if they did not respond to the survey. All ATP panelists that consented to SMS messages received an SMS invitation and up to two SMS reminders.

Data quality checks

To ensure high-quality data, the Center’s researchers performed data quality checks to identify any respondents showing clear patterns of satisficing. This includes checking for very high rates of leaving questions blank as well as always selecting the first or last answer presented. As a result of this checking, two ATP respondents were removed from the survey dataset prior to weighting and analysis.

Weighting

The ATP data was weighted in a multistep process that accounts for multiple stages of sampling and nonresponse that occur at different points in the survey process. First, each panelist begins with a base weight that reflects their probability of selection for their initial recruitment survey (and the probability of being invited to participate in the panel in cases where only a subsample of respondents were invited). The base weights for panelists recruited in different years are scaled to be proportionate to the effective sample size for all active panelists in their cohort. To correct for nonresponse to the initial recruitment surveys and gradual panel attrition, the base weights for all active panelists are calibrated to align with the population benchmarks identified in the accompanying table to create a full-panel weight.

For ATP waves in which only a subsample of panelists are invited to participate, a wave-specific base weight is created by adjusting the full-panel weights for subsampled panelists to account for any differential probabilities of selection for the particular panel wave. For waves in which all active panelists are invited to participate, the wave-specific base weight is identical to the full-panel weight.

In the final weighting step, the wave-specific base weights for panelists who completed the survey are again calibrated to match the population benchmarks specified above. These weights are trimmed (typically at about the 1st and 99th percentiles) to reduce the loss in precision stemming from variance in the weights. Sampling errors and test of statistical significance take into account the effect of weighting.

The following table shows the unweighted sample sizes and the error attributable to sampling that would be expected at the 95% level of confidence for different groups in the survey.

Sample sizes and sampling errors for other subgroups are available upon request. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
