Here are some graphs on the income and wealth gap between Whites and Blacks in the U.S.
This next one shows homeownership rates. I know some people are going to point out that Blacks are more concentrated in urban areas than Whites are, and so it might make more sense to break down homeownership by area (rural, urban, suburban). While that might be a legitimately useful comparison, it also brings up the question of why African Americans would be more concentrated in urban areas, which could lead to a discussion of government programs that encourage Whites to buy homes in the suburbs after WWII while denying those opportunities to Blacks.
One way of explaining higher unemployment rates among Blacks is that there is some individual or cultural deficiency–African Americans are lazy, or want a hand-out, or don’t look for work, etc. etc. I like to show trend comparisons like these because they undermine those types of explanations. If African American unemployment was due to laziness, a “culture of poverty,” or other deficiencies, it would be unlikely for Black and White unemployment rates to show the same pattern (or, for that matter, any pattern–unless you believe African Americans just got a lot lazier in, say, 1982). What we see here is that Black and White unemployment rates follow a very similar pattern, but that during hard economic times, sugh as the early 1980s and around 1992, African Americans suffer disproportionately.
This one shows the slow but steady trend toward resegregation of our schools:
