However, by the 1930s, the neighborhood was hit hard by job losses in the Great Depression. In the early 1930s, 25% of Harlemites were out of work, and employment prospects for Harlemites stayed bad for decades. Employment among black New Yorkers fell as some traditionally black businesses, including domestic service and some types of manual labor, were taken over by other ethnic groups. Major industries left New York City altogether, especially after 1950. Several riots happened in this period, including in 1935 and 1943.
