A majority of Americans oppose paying reparations to descendants of slaves, according to a Hill-HarrisX poll.

The survey found that 56 percent of registered voters were in agreement that reparations were not necessary because these “harms have been been adequately compensated.” Twenty percent of respondents said they were in favor of reparations, while 24 percent said they were unsure.

The idea was a divisive issue among voters along party lines.

Eighty-one percent of Republicans opposed reparations, compared to 36 percent of Democrats. More than half of Independents — 57 percent — meanwhile said the same.

When broken by race, the poll showed that 55 percent of black voters support some form of compensatory payment, compared to only 11 percent of white voters.

The poll also found that the older voters were, the less inclined they are to support the notion.

Sixty-nine percent of Americans 65 and older said that there were not in favor of reparations.

Reparations has become a topic of debate in the Democratic presidential primary.
