Last year the U.S. experienced something that hasn’t definitively occurred since the Great Depression: More people moved out than moved in. The Trump administration has hailed the exodus—negative net migration—as the fulfillment of its promise to ramp up deportations and restrict new visas. Beneath the stormy optics of that immigration crackdown, however, lies a less-noticed reversal: America’s own citizens are leaving in record numbers, replanting themselves and their families in lands they find more affordable and safe.?

Since the Eisenhower administration, the U.S. hasn’t collected comprehensive statistics on the number of citizens leaving. Yet data on residence permits, foreign home purchases, student enrollments and other metrics from more than 50 countries show that Americans are voting with their feet to an unprecedented degree. A millions-strong diaspora is studying, telecommuting and retiring overseas.
