The most accurate response regarding the consequences of the Great Depression on the African American community in Harlem is:
Unemployment increased by about 25 percent.
During the Great Depression, the already high unemployment rates among African Americans rose significantly, exacerbating economic hardships in Harlem and affecting the community's overall stability and prosperity. The other responses either do not accurately reflect the situation in Harlem or are less relevant to the specific impact of the Great Depression on the community.
