Gerrymandering has clearly affected the demographics of Congress to the point that it is no longer representative of the populations it is suppose to represent.

Democrats got 54,301,095 votes while Republicans got 53,822,442. That should mean that Congress should have a slight advantage in numbers for Democrats if we went by the votes.
