White Southerners in counties with higher concentrations of slaves in 1860 are today less Democratic, less supportive of affirmative action, and more resentful of blacks than other Southerners. Each data point above represents the aggregate attitudes of an individual county. The light red shaded area indicates the margin of error, which increases at the higher end because only a handful of counties had populations that were more than 80 percent slave.
