How is the town of Millwood characterized in the novel, The Queen of Palmyra?

The main characterization of Millwood during the time when the novel is set is that it's in throngs of segregation, the enforced political state requiring blacks to live in separate neighborhoods from whites, use separate bathrooms, drinking fountains, swimming pools, schools, and much more. As a result of segregation, blacks couldn't hold certain jobs, shop at certain stores, or ride on certain busses.
