Though relatively average by global standards, the 16% of Americans overall who said in 2017 and again in 2018 that they would like to permanently move to another country -- if they could -- is higher than the average levels during either the George W. Bush (11%) or Barack Obama administration (10%).
While Gallup's World Poll does not ask people about their political leanings, most of the recent surge in Americans' desire to migrate has come among groups that typically lean Democratic and that have disapproved of Trump's job performance so far in his presidency: women, young Americans and people in lower-income groups.
During the first two years of the Trump administration, a record-high one in five U.S. women (20%) said they would like to move to another country permanently if they could. This is twice the average for women during the Obama (10%) or Bush years (11%) and almost twice the level among men (13%) under Trump. Before the Trump years, there was no difference between men's and women's desires to move.
