Slavery United States 1861.
Also published in 1861, Edwin Hergesheimer’s landmark map entitled Map showing the distribution of the slave population of the southern states of the United States… also provides statistics on the slavery in the southern portion of the country. The differences between the two maps, both published in 1861 and both based on 1860 census data, are the methods in which the data is portrayed. Hergesheimer’s map breaks down the data into the percentage of slaves per county as opposed to the total county population. The choice of shading from lower percentages per county in light grey to higher percentages illustrated in darker tones, including a contrasting type color, provides a dramatic representation of slavery in the southern states.
