American Immigration Institute
The American Immigration Institute is a program of the Alexis de Tocqueville Institution. It was responsible for at least two reports.
- "A 1990 survey of 38 leading U.S. economists (including seven Nobel winners), conducted jointly by the Hudson Institute, the American Immigration Institute, and the Alexis de Tocqueville Institution, found that 80 percent believe that 20th-century immigration has had "a very favorable impact on the nation's growth." Not a single one thought the impact had been unfavorable."
