White Anglo-Saxon Protestant
The 1921 Emergency Quota Act then the Immigration Act of 1924 restricted immigration according to national origins. While the Emergency Quota Act used the census of 1910, xenophobic fears in the WASP community lead to the adoption of the 1890 census, more favorable to White Anglo-Saxon Protestant (WASP) population, for the uses of the Immigration Act of 1924, which responded to rising immigration from Southern and Eastern Europe, as well as Asia.
