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.
