The small amount of Americans who favor increased immigration include just 14% of Republicans. In fact, more Americans think immigration should be decreased than increased, and by a nearly two-to-one margin, 41% vs. 22%. A third in the U.S. are satisfied with the level as it is.

Americans’ views on immigration have varied a bit in the past 15 years, with the dominant view shifting between decreasing immigration and maintaining it at the current level. Some of these changes may reflect the ebb and flow of Americans’ reactions to the 9/11 attacks in 2001 as well as rocketing unemployment in 2009, with both events triggering a temporary surge in anti-immigration sentiment.
