The map on the left displays the African American percentage for each US state in 1910. Contrast that with the map on the right displaying the African American percentage for each US state in 2010. The African American population in 1910 was very concentrated in the southeast, but over the next 100 years migration spread up the east coast and into the midwest – this distributing the population more evenly in the eastern half of the US. It is interesting to note that every state in the western US (was in 1910 and remains to be in 2010) below the national average in African American population. Mississippi continues to be the US state with the highest concentration of American Americans but has decreased from 56% in 1910 to 37% in 2010. Nationwide the African American population has remained stable over the past 100 years -from around 10.7% in 1910 to 12.6% in 2010.
