The poll, released Thursday, found that 45 percent of Hispanic adults living in the United States thought the impact of unauthorized immigration on Hispanics already living in the United States was positive.
That number is up 16 percentage points from 2010, the Pew Research Center said.
More foreign-born Hispanics than native-born Hispanics agreed with the same statement, the poll found.
Fifty-three percent of Hispanic immigrants thought the impact of unauthorized immigration was positive, up 19 percentage points from 2010.
Thirty-five percent U.S.-born Hispanics agreed with the same statement, up from 24 percent in 2010.
The poll was conducted by landline and cellular telephones from May 24 to July 28 and included a nationally representative sample of 5,103 Hispanic adults. The margin of error was 2.1 percent.
