Explanation:
New research by Stanford economist Ran Abramitzky studies Norwegian immigrants to the U.S. during the late 19th and early 20th centuries who chose to return to Europe. Return migrants hailed from poorer backgrounds but ended up holding higher-paid occupations back home.
In the late 1800s, people in many parts of the world decided to leave their homes and immigrate to the United States. Fleeing crop failure, land and job shortages, rising taxes, and famine, many came to the U. S. because it was perceived as the land of economic opportunity. Others came seeking personal freedom or relief from political and religious persecution, and nearly 12 million immigrants arrived in the United States between 1870 and 1900
