The US fell in the rankings due to its perceived economic inequality, according to the data publisher.
More than 21,000 people worldwide participated in the Best Countries survey, in which they assessed how closely they associated 80 countries with specific characteristics.
Four of these – "economically stable," "good job market," "income equality" and "is a place I would live" – were included in the ranking.
Data on migrant populations from the World Bank and the United Nations was also used to determine the outcome of the rankings.

"While our methodology did not focus on refugees specifically, it did take into account immigration policies and integration measures per analysis from the United Nations," Deidre McPhillips, a data reporter who helped design the rankings, told the Washington Post.
"Our aim with this package was to focus on the economic aspects of immigration and the impacts this could have on a country's perceived standing in the world."
