The idea that the 1920s and 1930s were periods of high U.S. immigration is a misconception. Immigration was high in the late 1800s and early 1900s, but it collapsed after 1924 and fell to some of the lowest levels in U.S. history during the 1930s. Recent decades far exceed the 1920s–30s in both absolute numbers and share of the population.

The true “high‑immigration era” was ~1880–1924, not the 1920s–30s

• Annual arrivals peaked in 1907 at over 1.2 million — a record that stood for decades.
• The foreign‑born share reached ~15% in 1910, the highest until the 2020s.

This is the period people often think of when they imagine Ellis Island, steamships, and “waves” of European immigration.

The 1920s were not a high‑immigration decade

The Immigration Act of 1924 imposed strict national‑origins quotas:

• Capped each nationality at 2% of its 1890 population in the U.S.
• Deliberately slashed immigration from Southern and Eastern Europe.
• Total annual admissions dropped to well below 300,000 in most years.

The 1930s saw some of the lowest immigration in U.S. history

• The Great Depression further reduced arrivals to near-zero levels.
• Emigration sometimes exceeded immigration — net migration was close to zero or negative.

How do the 1920s–30s compare to today?

Foreign‑born share of the population

Year/Period	Foreign‑born share	Notes
1910	~15%	High point of the Ellis Island era.
Early 1970s	4.7%	Modern historical low.
Early 2025	15.87%	Highest in U.S. history (slightly above 1910).
1920s–30s	Much lower than 1910; falling sharply	Quotas + Depression crushed inflows.

Annual immigration numbers

Period	Typical annual admissions	Context
1900s–1910s	800k–1.2M	Peak Ellis Island era.
1920s	<300k	Quota system sharply restricted entries.
1930s	Near zero	Depression + quotas.
1990s–2020s	~700k–1.2M LPRs per year	Comparable to early 1900s in raw numbers, but U.S. population is much larger.

Why the meme exists

Several factors contribute to the misconception:

• Ellis Island imagery: People associate “the 1920s” with the tail end of the Ellis Island era, even though the big wave had already peaked.
• Cultural memory: Many Americans have grandparents or great‑grandparents who arrived around that era, even if the peak was earlier.
• Confusion between decades: The “Great Wave” runs into the early 1920s, but the restrictive 1924 law changed everything.

Bottom line

• High immigration? Yes — but 1880s–early 1920s, not the 1920s–30s.
• 1920s–30s immigration? Historically low, due to restrictive laws and the Depression.
• Today? The U.S. foreign‑born share (15.87%) is the highest ever recorded, slightly above the 1910 peak.
