A history in motion
The scale behind so many family stories.
Migration statistics cannot tell an individual family’s whole story. They can, however, help place a remembered village, a name on a passenger list, or a first arrival in a wider historical frame.
For Piccolo Santino, the journey from Calabria to New York belongs to a later chapter of that continuing story. These figures are gathered here as a clear starting point for readers, writers, and families tracing the Italian American past.

The numbers
Italian immigrants arrived between 1820 and 1870.
Most came from northern Italy, before the far larger movement that followed later in the century.
Library of Congress, Early Arrivals, Library of Congress teaching resource, accessed 2026 ↗Italian immigrants came to the United States in the 1880s.
That decade marks the beginning of a dramatic acceleration in migration from the Italian peninsula.
Library of Congress, The Great Arrival, Library of Congress teaching resource, accessed 2026 ↗Italian immigrants came to the United States in the 1890s.
The total was twice the figure reported for the preceding decade.
Library of Congress, The Great Arrival, Library of Congress teaching resource, accessed 2026 ↗Italian immigrants arrived in the decade after 1900.
It was the largest single decade in the Library of Congress summary of the great arrival.
Library of Congress, The Great Arrival, Library of Congress teaching resource, accessed 2026 ↗Italians had come to the United States by 1920.
At that point, Italians represented more than 10% of the nation’s foreign-born population.

A few useful guardrails.
These figures describe movements and records, not a single, uniform experience. “Italian” could stand alongside regional identities such as Calabrian, Sicilian, Neapolitan, or Piedmontese, and passengers arrived for different reasons and under different circumstances.
The National Archives figure refers to a defined historical data series, rather than every Italian arrival. The ancestry figure is a modern survey estimate, not a count of people born in Italy. Each source is linked so that a reader can see its scope directly.
