Pundits often assume a minority group has a homogeneous opinion, that members of a particular race will share political values and vote the same way.

The reality, of course, is far more nuanced. New research charts the way values vary between African-American communities in regions of the United States with different histories of racism and discrimination.

The issue: Gaps in student achievement often fit familiar patterns. Children from wealthy families generally perform better on tests than students from poorer families; white students tend to do better than black or Hispanic students.
