U.S. Naturalization

The Economist's recent Daily Chart depicts the number of naturalizations that occurred over the past decade in a handful of countries.  The graph also displays the proportion of each country's population that is foreign born.


The nations that naturalized the most citizens were the United States, Russia, and Canada. With a figure of 6.6 million, the United States naturalized the most citizens from 2001-2010. Russia comes in second, with about half as many naturalizations at 3.1 million people, while Canada follows with just under 2 million naturalized citizens in just as many years. Other countries with more than a million naturalized immigrants are Britain, France, and Germany.

However, the countries that naturalized the most immigrants are not necessarily the ones whose populations have the greatest proportion of foreign born people.  For example, while the United States conferred citizenship on 6.6 million individuals in the past decade, immigrants only account for 13% of its total population.  On the other hand, Australia and Switzerland naturalized 1 million and about 0.4 million people, but both their foreign born populations constitute 27% of the total population, the most of any countries depicted in the graphic.  Countries with other high proportions of foreign born people are New Zealand (23%), Canada (20%), Spain (15%), and Sweden (15%).
