Answer:
Had more than doubled since 1900.
Step-by-step explanation:
In this graph, we learn about the ways in which the African population of these regions changed between 1900 and 1930. We learn that in the Midwest, the population went from 500,000 in 1900 to 1,250,000 in 1930. On the other hand, in the Northeast, the population increased from 480,000 in 1900 to 1,115,000 in 1930. This means that in both regions, the population of African Americans more than doubled. This was most likely a consequence of a phenomenon known as the Great Migration, which saw the movement of thousands of African Americans from the South to other regions of the country.
