INTERNAL MIGRATIONWhile large numbers of New England farming families joined the migrant streams to western New York and the midwestern states, others migrated much shorter distances to the region's rapidly growing urban centers. Between 1810 and 1860, the proportion of New Englanders living in cities increased from 7 to 36 percent. Single men and women commonly migrated to mill towns or larger, commercial cities to work for a number of years. Many married and remained in these cities rather than return to their rural hometowns. Still other rural families gave up their farms and migrated together to cities. This internal migration was far shorter than the move to new lands in the West but made an equally significant contribution to the changing character of American life in the nineteenth century.
The years between 1910 and 1930 saw a mass movement of southern black farmers, sharecroppers, and farm laborers to the urban North. This migration built upon earlier precedents. With emancipation, large numbers of freedmen and women had moved to reunite families separated under slavery. Moreover, with the end of Reconstruction, there had been a sizable black exodus to Kansas beginning in the late 1870s and to Oklahoma in the 1890s. In the twentieth century, the lure of higher wages in the North, economic setbacks in the South, and the sting of growing racial discrimination motivated what came to be known as the Great Migration. New opportunities for blacks in northern industry during the labor shortages of World War I attracted 400,000 black migrants during the war period. The attraction did not abate at war's end, however, as more than 600,000 southern blacks migrated north in the 1920s...
