The South American country has the largest Italian population outside Italy.

2) Where did Sicilians immigrate?

Between around 1880 and 1924, more than four million Italians immigrated to the United States, half of them between 1900 and 1910 alone—the majority fleeing grinding rural poverty in Southern Italy and Sicily. Today, Americans of Italian ancestry are the nation's fifth-largest ethnic group.

3) What did Italian immigrants contribute to America?

Italian immigrants helped provide the labor for American factories and mines and helped build roads, dams, tunnels, and other infrastructure. Their work provided them a small economic foothold in American society and allowed them to provide for their families, which stood at the core of Italian-American life.
