The National Origins Act of 1924 was a federal law that capped immigration using nationality-based quotas (2% of each group's 1890 census count), deliberately favoring Northern and Western Europeans, slashing Southern and Eastern European immigration, and virtually banning Asian immigrants.
The National Origins Act of 1924 (also called the Johnson-Reed Act) was Congress's answer to decades of nativist pressure. It limited annual immigration from each country to 2% of the number of people from that country living in the U.S. in 1890. That date was the whole trick. The huge waves of "new immigrants" from Southern and Eastern Europe (Italians, Poles, Russian Jews, Greeks) mostly arrived after 1890, so pegging quotas to that census made their numbers tiny on purpose. The law also barred immigrants "ineligible for citizenship," which effectively shut out Japanese and other Asian immigrants entirely.
In CED terms, this is the payoff of a story that starts back in Unit 6. Industrial cities pulled in millions of immigrants seeking work and escaping persecution (KC-6.2.I.A), and Americans argued over assimilation, Americanization, and who counted as a "real" American. After World War I, nativist campaigns won. The 1924 act locked in restriction, and immigration stayed low until the system was dismantled in 1965.
This term sits at the intersection of Topic 7.8 (1920s cultural and political controversies) and Topics 6.8 and 6.9 (immigration and responses to it). It directly supports APUSH 7.8.A, which asks you to explain how postwar nativist campaigns "led to the passage of quotas that restricted immigration, particularly from southern and eastern Europe, and increased barriers to Asian immigration." That sentence in the CED is basically describing this law. It also caps the continuity-and-change story under APUSH 6.9.A, where Gilded Age debates over assimilation and Social Darwinist thinking harden into actual federal restriction by the 1920s. For the Migration and Settlement theme, the 1924 act is the single clearest example of the government deciding who gets to become American.

Nativism (Units 6-7)
Nativism is the attitude; the National Origins Act is the attitude turned into law. If an essay asks how anti-immigrant sentiment shaped policy, this act is your strongest piece of evidence that nativism won at the federal level.
Immigration Act of 1917 (Unit 7)
The 1917 act was the warm-up. It required a literacy test and created the Asiatic Barred Zone, restricting immigrants by ability and region. The 1924 act went further by restricting people based purely on national origin, no test required.
Immigration Quota (Unit 7)
The quota system is the mechanism inside the act. The Emergency Quota Act of 1921 first capped immigration at 3% of the 1910 census; the 1924 law tightened it to 2% of the 1890 census, deliberately shrinking the count for Southern and Eastern Europeans.
A. Mitchell Palmer and the Red Scare (Unit 7)
The Palmer Raids of 1919-1920 targeted immigrants as suspected radicals, fusing anti-communism with nativism. That postwar fear is exactly the climate that made quota legislation politically easy to pass a few years later.
Multiple-choice questions usually pair this law with a 1920s nativist source (a Klan pamphlet, a political cartoon, a congressional speech) and ask you to identify the act's purpose or the sentiment behind it. Practice questions hit exactly this angle, asking what the act's primary aim was and how national-origins quotas reflect nativist attitudes. Be ready to explain the 1890 census trick, not just say "it limited immigration." No released FRQ has used the term verbatim, but it's prime evidence for LEQs and DBQs on continuity and change in immigration policy, where you can trace Gilded Age anti-immigrant debates (6.9) through the 1917 literacy test to the 1924 quotas, then note the system lasted until 1965.
Both are restrictionist laws, but they restrict differently. The 1917 act used a literacy test and the Asiatic Barred Zone, so an immigrant who could read and came from outside the zone could still enter. The 1924 act used numerical quotas tied to national origin, so it didn't matter how literate or skilled you were; if your country's quota was full, you were out. Think of 1917 as a filter and 1924 as a hard cap.
The National Origins Act of 1924 capped annual immigration from each country at 2% of that nationality's population in the 1890 census.
Using the 1890 census was intentional, because most Southern and Eastern European immigrants arrived after 1890, so their quotas came out tiny.
The act virtually ended Asian immigration by barring anyone "ineligible for citizenship."
It's the culmination of nativist pressure that built from the Gilded Age through the post-WWI Red Scare, which is why it spans Units 6 and 7.
On the exam, use it as evidence for APUSH 7.8.A and as the endpoint of a continuity-and-change argument about responses to immigration that starts in Topic 6.9.
The quota system stayed largely in place until the Immigration and Nationality Act of 1965 replaced it.
It limited immigration from each country to 2% of that nationality's U.S. population in the 1890 census, sharply cutting Southern and Eastern European immigration and effectively banning Asian immigration. It made nativist restriction permanent federal policy.
Because the "new immigrants" from Italy, Poland, Russia, and Greece mostly arrived after 1890. Basing quotas on 1890 numbers made their allotments tiny while keeping the door relatively open for Northern and Western Europeans.
No. It capped and filtered immigration rather than ending it. Northern and Western Europeans still entered under generous quotas, and immigration from the Western Hemisphere (like Mexico and Canada) was not subject to the quota system at all. Asian immigrants, however, were almost entirely excluded.
The 1917 act restricted by test and geography, requiring a literacy test and creating the Asiatic Barred Zone. The 1924 act restricted by numbers, assigning each country a quota based on national origin. The 1924 law was far more sweeping and discriminatory by design.
Yes. It's core content for Topic 7.8 under learning objective APUSH 7.8.A, which covers postwar nativist quotas. Expect it in multiple-choice sets on 1920s controversies and as evidence in essays about immigration policy across Periods 6 and 7.
