The migration of African Americans to Kansas began in the Eastern section of the state.  The county with the most Blacks was Wyandotte. In 1960, Graham County showed the least Blacks.  The first change in population was from 1910 (11,172) to 1920 (16,758) which was a jump of 5,586 people.  The second change was from 1940 (23,017) to 1950 (29,367), showing a total of 6,350 people in that year.  It also showed a difference of 764 people from the last change.  Every other year had a change of about two thousand people for the Wyandotte County population.
    The two greatest changes for Wyandotte County came in the periods 1910-1920 and 1940-1950.  Linn County had the greatest decrease between the years of 1900 (16,689) to 1910 (14735) where 1,954 people had either passed way or moved out.  Sedgwick County experienced the greatest increase in 1950- 1960 an increase in population from 9746- 20469. Wyandotte County showed another great increases in Kansas migration of Blacks.
    Sedgwick County started as a slow-growing county with only nine Blacks; however, it increased to 20,469 in 1960 with a gain of 10,723 people in one year (1950- 1960).  Wyandotte County doesn't have the greatest population of Blacks, although it showed a good increase in that population.  Sedgwick County had the greatest increase of the Black population in Kansas's history.
    In conclusion, I think that the best counties to do a research on would be the eastern counties of Kansas because that is where most of the Blacks come from and have settled.  For western counties, I suggest Stevens County because I did not see Stevens County in 1870; nevertheless, it appeared in 1880 and on.  It will be interesting to find out why Stevens was or was not a growing area in Kansas.
    I’d also suggest Davis County because after 1880, it was cut off.  I think it might have been renamed something else.  There were no clues as to why Davis County was not found on the Kansas map at all.
