The Proportional House — mapping the U.S. House under proportional representation.
The U.S. Courts of Appeals are divided into 12 geographic circuits of wildly unequal size. The 9th Circuit covers 66.8 million people — about one in five Americans — against 14.2 million in the 1st, a 4.7× spread across 167 authorized active judgeships. This page maps today's circuits by population and judges alongside an illustrative redraw that narrows that spread to 1.9×.
