The West Indians had an ethos which stressed saving, education, and hard work. The same self-confidence and initiative which enabled substantial numbers of them to move into professional employment made others into political radicals. Unaccustomed to the intensity of racial hostility and harassment which they found in America, they reacted with anger. They had not been trained since birth in attitudes of submission and nonresistance. This was the phenomenon which created Marcus Garvey and the United Negro Improvement Association. The West Indian community had been gradually merging with the larger Afro-American society. It never established a separate place of residence, and the second generation became mixed with the larger Afro-American community. After the Second World War, there was a fresh wave of emigration from the West Indies to America, but the 1952 Immigration Act drastically reduced the West Indian quota, thereby 'deflecting this stream of emigrants to Britain.

In contrast, the Spanish-speaking immigrants from the Caribbean did establish separate communities. After the United States acquired Puerto Rico, a sizeable number of Puerto Ricans moved to the mainland. This flow began as a trickle at the beginning of the century, and it has grown rapidly since. Most of the Puerto Ricans settled in urban centers in the Northeast, and they established a large, Spanish-speaking community in New York City. The migration of Cubans into America, while not as large, has been important in both Miami and New York. The largest number of Cubans came during the 1950s and 1960s.

In 1910, the Puerto Rican community in New York City numbered only five hundred, but by 1920 it had grown to seven thousand. In 1940, the number of New York residents who had been born in Puerto Rico reached seventy thousand, and in 1950, it jumped to one hundred eighty seven thousand. The 1960 census showed that the Puerto Rican community of New York City, including those born in Puerto Rico as well as those born in America of Puerto Rican parentage, had reached 613,000.

The Spaniards in Latin America had intermarried with both the Indians and Africans to a far higher degree than had the Anglo-Saxons in North America. For this reason, it is much more difficult to identify the racial background of individual Puerto Ricans. Certainly, there was a significant African influence on the entire population of the island. In 1860, it was estimated that almost 50 percent of the island's residents were Negro. In 1900, the percentage had dropped to 40 percent, and, by 1950, it had dropped to 20 percent. The change in these statistics was due to assimilation through intermarriage. Those who migrated to the continent did not include many with dominant negroid characteristics. The 1960 New York City census listed only 4 percent of its Puerto Ricans as being Negro. Nathan Glazer and Daniel P. Moynihan, in their study of this community, believed that the Puerto Rican racial attitudes may alter the racial views of the entire city and thereby have some effect on the nation. Puerto Ricans are not as race conscious as are most Americans. Most of them are not clearly either black or white. Intermarriage between color groups is common. The Puerto Rican community in New York City is more conscious of being a separate, Spanish-speaking community than it is of being either a black or white one.

The other major Caribbean element in the American Spanish-speaking community comes from Cuba. In 1960, the Cuban community in the United States, including those born in Cuba as well as those born in America of Cuban parentage, totaled 124,416. Only 6.5 percent of this community is nonwhite, while 25 percent of the population in Cuba is nonwhite. The Cuban community in the United States has almost 46 percent of its number living in the Northeast, and it has another 43 percent living in Florida. Almost the entire community is divided between the cities of Miami and New York.

This immigration of foreign-born blacks into the cities of the North and West was concurrent with a sizeable movement of American blacks from the rural South into these same cities. Actually, this internal migration was not new. As soon as the Northern states had begun to abolish slavery, runaways from the slave states in the South began to trickle into the North. As the underground Railway developed, this trickle swelled into a sizeable flow.

Immediately after the Civil War, the flow reversed directions for a short time. Many who had run away during the war returned home to be with friends and family. Thousands of others, born in the North, hurried south to help educate and rehabilitate their brothers. However, this flow was short-lived. As the South moved from slavery into segregation, hope slid into disillusionment and cynicism. In 1878-79 there was a wave of migration from the south into the West. "Pap" Singleton, an ex-slave from Tennessee, had come to the conclusion that the ex-slaveholder and the ex-slave could not live together in harmony, and he believed that the best solution was to develop a separate society. As a result, he formed the Tennessee Real Estate and Homestead Association, but there was not enough land available in Tennessee for the program. Finally, he decided that Kansas was the ideal location in which to build a separate Negro society. Various transportation companies saw this scheme as a way for them to make money, and they encouraged this westward migration. Although the original migrants to Kansas were welcomed, opposition grew as their numbers increased. Before his death in 1892, Singleton became disillusioned with the possibilities of developing a separate society anywhere in the United States, and he came to favor a return to Africa. He believed that this was the only place where his people could escape racial discrimination. Nevertheless, Singleton took pride in his work, and he claimed, probably with some exaggeration, to have been responsible for transporting some 82,000 Afro-Americans from the South into Kansas.

Another ex-slave, Henry Adams, called a New Orleans Colored Convention in 1879 to examine the condition of the ex-slave throughout the South. A comittee was formed for this purpose. It found the situation discouraging and recommended migration into other regions. Another convention held in Nashville reached similar conclusions, and it requested funds from Congress to assist in the process. Funds were not forthcoming. When Congress did investigate this vast migration, Southerners assured the comittee that their Negroes were really very happy, and they claimed that "the migration was a myth."

In spite of this earlier migration, the 1900 census showed that 89.7 percent of the Afro-American community still resided in the South. One-third of the Southern population was nonwhite. The real exodus still lay ahead.

The migrants were moved both by forces within the South which pushed them out and by those within the North which pulled them in. On one hand, continuing violence and segregation drove many to leave their homes. When the boll weevil spread across the Southern states like a plague, it wiped out many poor farmers, and it drove them to seek other means of livelihood elsewhere. On the other hand, the war had interrupted the flow of immigrants from Europe into the Northern industrial centers, and at the same time it created the need for even more unskilled labor in the factories. After the war, the restrictive immigration laws which were passed kept the flow of European immigration low, and Northern industry continued to draw labor from the Southern rural pockets of poverty.
