Supplementary notes
*The total number for 1870 has been corrected from previous years, however no data is available for the male or female figures. Therefore the difference between the new and old figures has been split and evenly distributed to the total male and female figures for 1870. The original records state that the total number of black men was 2393263, and black women was 2486746.
