The value of young, immigrant entrepreneurs

See Send Us Your Young, Your Educated: There is an excess supply of potential immigrants. The U.S. should be smart about whom it chooses by Edward P. Lazear. Excerpts:

"immigrants are about 20% more likely than native-born Americans to found new companies."

"an immigrant college graduate is 38% likelier to found a business than an immigrant high-school graduate."

"Immigrant entrepreneurs with only high-school educations report average annual earnings less than half those of entrepreneurs with college educations or more."

"those who arrive when young are likelier to found businesses than those who come as adults. An immigrant who arrives before turning 20 is 34% likelier to start a company than one who arrives after 35."

"The most entrepreneurial immigrants come from Israel, Iran, Syria, Lebanon and Greece. More than 9% of the immigrants from these countries founded an incorporated business, a proportion that is more than three times that of native-born Americans."

"Immigrants from countries that are underrepresented among the U.S. immigrant population have rates of entrepreneurship about 60% higher than those from overrepresented countries."
