The Immigration Act of 1924 produced highly discriminatory results because it set a max on how many immigrants could come to the US depending on what country they came from.

For example, there were many more opportunities for citizens from countries like Germany, Great Britain, and Sweden in comparison to individuals from Italy or Russia. Here are some numbers to support this claim:

Germany's Quota (aka amount that could come into US) - 51,227

Great Britain and Northern Ireland's Quota - 34,0007

Sweden's Quota - 9,561

Italy's Quota - 3,845

Russia's Quota-2, 248.
