Rep. Ilhan Omar (D-Minn.) represents the very worst congressional district for disparities between blacks and whites, according to a new study. Democrats represent the vast majority of the worst congressional districts for black Americans. President Donald Trump made news criticizing Rep. Elijah Cummings (D-Md.) for the poverty in his district, and his district is on the list. Interestingly, none of the other members of “The Squad” — Reps. Alexandria Ocasio-Cortez (D-N.Y), Ayanna Pressley (D-Mass.), and Rashida Tlaib (D-Mich.) — appeared on the list with Omar.

Congressional districts each represent roughly 700,000 Americans, but they are often apportioned to favor one political party over another and do not represent well-defined communities. This list is little more than interesting demographic data, and there is little a member of Congress can do specifically for his or her district beyond things like pet projects or “pork barrel” spending attached to unrelated legislation. Members of Congress go to Washington, D.C., to represent their districts, but mostly for lawmaking purposes.

Even so, the data from the study is quite interesting. The organization 24/7 Wall St. noted that the median black household earns about $25,000 per year less than the median white household. Black workers are also more than twice as likely to be unemployed, even with the black unemployment rate reaching historic lows under President Trump.

There are 174 congressional districts (of 436 total) with a black population of 10 percent or more, so the 30 worst districts represent less than a fifth of those.

For the study, 24/7 Wall St. created an index to measure social disparities between black and white Americans by congressional districts using U.S. Census Bureau data. Using that index, the organization discovered the 30 worst districts for black Americans, by measuring disparities between blacks and whites when it comes to the poverty rate, the unemployment rate, and the homeownership rate in each district.

A full 25 of the 30 districts are represented by Democrats.
