Immigration and emigration have played a prominent part in Cuba's demographic profile. Between the 18th and early 20th century, large waves of Canarian, Catalan, Andalusian, Galician, and other Spanish people immigrated to Cuba. Between 1899 and 1930 alone, close to a million Spaniards entered the country, though many would eventually return to Spain. Other prominent immigrant groups included French, Portuguese, Italian, Russian, Dutch, Greek, British, and Irish, as well as small number of descendants of U.S. citizens who arrived in Cuba in the late 19th and early 20th centuries. As of 2019, the foreign-born population in Cuba was 4,886 inhabitants in UN data.
