After hitting a new high last month, mentions of immigration as the most important problem facing the U.S. increased further to 27% in July. Since Gallup began regularly recording mentions of the issue in 1993, immigration has been cited by an average of 6% of Americans, though it has been higher in recent years. There have been occasional, typically short-lived, spikes when major immigration events were occurring…

Republicans have typically been more likely than Democrats and independents to name immigration as the most important problem, and that is still the case. In the latest survey, 42% of Republicans, 20% of independents and 20% of Democrats mention immigration.

All political groups are more likely to mention immigration now than earlier this year. In March, when a 2019-low 16% of Americans identified immigration as the most important problem, 31% of Republicans, 14% of independents and 6% of Democrats did.
