The Great Migration: The Guagua Aérea to New York

Puerto Ricans had been able to travel to the U.S. mainland without a passport since the Jones-Shafroth Act of 1917, but for decades the cost of the trip kept that legal right mostly theoretical. What changed in the years after the Second World War was affordable air travel, and it is credited as the key enabler of what came to be called the Great Migration of the 1950s. Puerto Rico's own Department of Labor opened a Migration Division office in New York City in 1948, specifically to help newcomers find jobs and housing once they landed.

The scale of the movement, once it began, was enormous. From 1946 to 1950, an estimated 31,000 Puerto Ricans migrated to New York each year. The migration peaked in 1953, when an estimated 75,000 people left the island in that single year; about 40,000 had already settled in New York City by 1946, and another 58,500 arrived between 1952 and 1953. By 1960, the U.S. Census counted well over 600,000 New Yorkers born in Puerto Rico or with Puerto Rican parents, and broader estimates suggest more than a million people migrated during this period in total, a figure that reshaped both the island and the city receiving them.

The migrants built entire neighborhoods around themselves. East Harlem, known as El Barrio or Spanish Harlem, the South Bronx, and parts of Brooklyn filled with bodegas, piragua carts selling shaved ice, and new community institutions, including ASPIRA, founded in 1961 by Antonia Pantoja to support Puerto Rican youth. None of this happened without resistance from the city they moved to. Discrimination was widespread and well documented: Lolita Lebrón, discussed in another lesson on this site in connection with the 1954 Capitol shooting, recalled restaurant signs saying "No dogs or Puerto Ricans allowed," and the aftermath of that same shooting further hardened anti-Puerto Rican feeling among some mainland Americans in those same years, adding political weight to an already difficult reception.
