PRINCETON, N.J. -- Despite Donald Trump's continued emphasis on the harmful effects of various types of immigrants coming to the U.S., there is no evidence of a surge in the percentage of Americans wanting to see immigration levels decreased. Thirty-eight percent of U.S. adults say the level of immigration should be decreased, similar to recent years, while an equal percentage say immigration should be kept at its present level. The relatively small percentage of Americans who want immigration increased, however, has edged down this year to 21%.

Since 2012, Americans generally have remained split between maintaining the current level of immigration and decreasing immigration, with less interest in increasing immigration. By contrast, before 2012 -- and particularly in the years immediately after 9/11 -- Americans tended to be more in favor of decreased immigration.

麻豆传媒AV's question about changes in the volume of "immigration" does not specify whether it is legal or illegal, meaning respondents could, in theory, be taking both into account.

Immigration has been a major focus of Trump's presidential campaign since it began, including proposals to restrict the number of low-wage workers coming into the U.S. legally. He has also proposed restricting legal immigration among those who come from certain regions of the world with a history of exporting terrorism, who don't pass an ideology test or who identify with the Muslim faith. Trump has also proposed building a wall between the U.S. and Mexico to prevent illegal immigration and to deport the millions of immigrants living illegally in the U.S. -- although news reports now indicate that he may alter his position on that issue.

Partisanship Creates the Biggest Divide on Immigration Attitudes

Americans' views on changes in the volume of immigration vary across key subgroups, particularly along party and ideological lines. Republicans and conservatives are most likely to want immigration decreased, while Democrats and liberals are least likely to want it decreased. The range across the political and ideological subgroups goes from 60% of Republicans and Republican leaners who want immigration decreased down to 20% among Democrats and Democratic leaners.

There is less variation among racial and ethnic groups in views on immigration levels. Whites are somewhat more likely than Hispanics to want immigration decreased, while blacks are the least likely. The small group of those interviewed who identify as immigrants (12% of survey respondents in this poll) are somewhat less likely to want immigration decreased than are those who have been in the U.S. for at least two generations (26% vs. 40%, respectively). Twenty-four percent of immigrants want immigration increased, not far from the overall sample average.

Most Americans Define Immigration in General as "Good"

A separate question confirms that most Americans (72%) believe that immigration is a "good thing for this country today." Americans' positive views about immigration dipped to a low point after 9/11 and have fluctuated since then, but the 72% and 73% "good thing" percentages measured in 2013, 2015 and this year are the highest in 麻豆传媒AV's trend dating back to 2001.

Bottom Line

While most Americans believe immigration is good for the country, a relatively small percentage would like to see the nation's level of immigration increased, while the rest want it either to remain the same or to decrease. Despite the strong rhetoric on immigration emanating from the Trump presidential campaign, there has been no uptick in the past year of those wanting to see immigration decreased, suggesting that Trump is not so much changing public opinion as he is taking advantage of existing attitudes. Trump generally finds support for the idea of decreasing immigration among his conservative, Republican base. But the significantly lower level of support for decreasing immigration among non-Republicans underscores the challenge Trump faces in the general election -- given how closely tied he is to the issue -- and helps explain why he may be shifting his tone on some immigration-related policies.
