Concise explanatory introduction to the process of calculating
National Origins Formula
quotas allotted to each country to regulate annual immigration to the United States, as prescribed by subsections (b), (c), (d) of §11 of the
Immigration Act of 1924
. The complex formula to derive a country's quota as a proportional fraction of 150,000 turned out mathematically equivalent to multiplying the number of Americans of each national origin by 0.001675854857—so with 39,216,333 Americans of British origin in 1920, the quota for Great Britain rounded to 65,721. Described as “cumbersome” in this 1950 U.S. Senate Report by a Special Subcommittee to Investigate the Immigration System chaired by Senator
Pat McCarran
, reforms were adopted in the
Immigration and Nationality Act of 1952 (McCarran–Walter Act)
, whenceforth a simplified national origins formula was employed to yield roughly equivalent results—taking a flat one-sixth of 1% of the number of Americans of each national origin in 1920 to compute all quotas (equal to multiplying by repeating decimal 0.001666666̅...), which caused a slight drop in quota size for all countries after 1953 (e.g. Britain's quota fell to 65,361).
