economic devastation caused by years of fighting on the island. Other early waves (1900–1959) Several other small waves of Cuban emigration to the U.S. occurred in the early 20th century (1900–1959). Most settled in Florida and the northeast U.S. The majority of an estimated 100,000 Cubans arriving in that time period usually came for economic reasons (the Great Depression of 1929, volatile sugar prices and migrant farm labor contracts), but included anti-Batista refugees fleeing the military dictatorship, which had pro-U.S. diplomatic ties. During the '20s and '30s, emigration from Cuba to U.S. territory, basically comprised workers looking for jobs, mainly in New York and New Jersey. They were classified as labor migrants and workers, much like other immigrants in the area at that time. Thus migrated more than 40,149 in the first decade, encouraged by U.S. immigration facilities at the time and more than 43,400 by the end of the 30s. Subsequently, the flow of Cubans to the United States fluctuated, due to both the domestic situation in the 40s and 50s in Cuba, and U.S. immigration policies, plus intermittent anti-immigrant sentiment. Cuban Migration in those years included, in addition to workers, a small mass of the population who could afford to leave the country and live abroad. The U.S. was considered a favored destination by the Cuban bourgeoisie and the middle classes of society, to send their children to school, take vacations and bring some of their capital to establish small and medium-sized businesses. The Cuban population officially registered in the United States for 1958 was around 125,000 people including descendants. Of these, more than 50,000 remained in the United States after the revolution of 1959. Post-1959 revolution (1959–present) After the Cuban revolution led by Fidel Castro in 1959, a Cuban exodus began as the new government allied itself with the Soviet Union and began to introduce communism. The first Cubans to come to America after the revolution were those affiliated with former dictator Fulgencio Batista, next were Cuba's professionals. Most Cuban Americans that arrived in the United States initially came from Cuba's educated upper and middle classes centered in Cuba's capital Havana. This middle class arose in the period after the Platt Amendment when Cuba became one of the most successful countries in Latin America. Between December 1960 and October 1962 more than 14,000 Cuban children arrived alone in the U.S. Their parents were afraid that their children
