Democrats and the White House have made income inequality a focal point of their legislative agenda in Washington, D.C.

So where would that have the biggest effect? Where is income the most unequal/inequal?

Income inequality is actually most pronounced in red states -- particularly the American South. While Manhattan features the United States' most unequal incomes, six of the 10 most unequal counties in the United States are in the South, according to a Pew study.

Also ranking near the top (perhaps not surprisingly): Washington, D.C. at No. 27.
