Final answer:
The statement is false. The Great Migration North was due to a combination of factors, including job opportunities during World War I and to escape Jim Crow laws, not just immigration restrictions around 1900.
Step-by-step explanation:
The statement provided is false. The Great Migration North was not mainly in response to severe restrictions on immigration from Europe around 1900. Although immigration restrictions in the 1920s did affect the labor supply in northern factories, the Great Migration, which refers to the movement of approximately 1.5 million African Americans out of the American South mainly between 1910 and 1930, was due to several factors. The movement significantly increased during World War I as northern factories were in desperate need of workers because the war had cut off the flow of immigrants from Europe. African Americans were also looking to escape the oppressive Jim Crow laws and to find better job opportunities and living conditions.
The 'push' factors such as the threat of violence and racism, combined with the promise of industrial jobs ('pull' factors), led to the relocation of African Americans to cities like Chicago, Detroit, and New York. Although the war ended and many African Americans were forced out of wartime industrial jobs, the Great Migration continued due to ongoing economic opportunities and social conditions in the North that were perceived as better than those in the South.
