Those links offer some other interesting comparisons. There are about 700,000 U.K. citizens living in the U.S., and only about 160,000 U.S. citizens living in the U.K. The populations are about 63 million and 320 million, respectively. On a proportional basis, one would expect to see 5x more Americans living in the U.K., but in fact, there are 4x more U.K. citizens living in the U.S. Similar ratios apply for other countries. Germany has 1/4 the population of the U.S., but there are 5 times as many Germans living in the U.S. as there are Americans living in Germany. Voting with your feet never lies.
