WASHINGTON (CNN) - Most Americans would like to see fewer illegal immigrants in the country, but only three in 10 say all of them should be removed, a poll said Wednesday.
Just 7 percent of those polled said they would like to see the number of illegal immigrants increased; 22 percent said they would like the number remain the same; 16 percent wanted it decreased "a little"; and 22 percent wanted it decreased "a lot," the poll of 1,212 adult Americans found.
Blacks and whites differed over whether the number of illegal immigrants should be increased, with 14 percent of African-Americans saying they did, versus 3 percent of whites.
About one in five (19 percent) of blacks said they thought all illegal immigrants should be removed from the country, versus more than a third (35 percent) of whites who said that.
Blacks and whites overwhelmingly oppose state governments issuing driver's licenses to illegal immigrants, with 76 percent of blacks and 83 percent of whites taking that stance, the poll said.
The races differed more on whether state and local police should turn over any illegal immigrants they may encounter, even if they have broken no state or local laws. In such cases, fewer than half of blacks (45 percent) and nearly two-thirds of whites (61 percent) said they believe they should.
Asked whether people who cannot read or write English should be allowed to vote, 54 percent of blacks said they should, versus 43 percent of whites.
The Voting Rights Act of 1965 eliminated voting barriers such as a literacy test.
On a related topic, the public appeared split on foreign trade - 46 percent said they see trade more as an opportunity for economic growth, whereas 45 percent said they see it as a threat to the U.S. economy. Five percent said they see it as both an opportunity and a threat.
The telephone poll was carried out Friday through Sunday and had a sampling error of plus-or-minus 3.5 points.
