NEGRO INTELLIGENCE AND SELECTIVE MIGRATION: A Philadelphia Test of the Klineberg Hypothesis.

The article presents information on the migration of southern African Americans to northern cities after World War I and World War II, which resulted in a redistribution of the African American population. In his book "Negro Intelligence and Selective Migration," Otto Klineberg has written a method in which intelligence and performance tests are given to Negro children living in New York, and then a comparison is done between the groups with different lengths of residence in New York. After comparison, it was found that the earlier migrants were superior to the later ones.
