Americans divided about current immigration level
The poll, which has a 4 percent margin of error, also found 24 percent of Americans said immigration should increase.
In Gallup's 2016 poll, 38 percent of Americans said they think immigration should decrease, 38 percent said they think immigration should stay at the present level and 21 percent said it should increase.
"As a whole, Americans' attitudes about immigration haven't changed significantly since Donald Trump's presidential campaign platform promised action against illegal immigrants," Gallup wrote in a statement.
About 60 percent of Republicans and Republican-leaning independents last year said they wanted a decrease in immigration. In 2017, 48 percent said they want a decrease.
In 2017, about 23 percent of Democrats and Democratic-leaning independents said immigration should decrease, an increase of 3 percent from last year. ■
