The map I created represents the population of the United States Nonwhite female slavery in 1850. With this map, it allows me to see the population of different parts of the states easily base the shade of blue. For instance, there is higher number of nonwhite female slavery population with a darker blue. on the contrary, there is a lower number of Nonwhite female slavery population with a shallower blue.
Moreover, I can also click on a county on the map, there is more data about the population based on different ages. Taking Amherst as an example, there were even 26 nonwhite female slaves under 1 year old, 488 at the age of 1 to 4, 474 at the age of 5 to 9, which really surprised me.
In addition, I also found that there were population of Nonwhite female slavery in the northern parts of the country.
To conclude, a map enables data appears visually with a geographic space and helps the learning process of history.
