The amendment lays out a mathematical formula for determining the number of seats in the House of Representatives. It would initially have required one representative for every 30,000 constituents, with that number eventually climbing to one representative for every 50,000 constituents. However, there is some agreement that the last line contains a scrivener's error (see Mathematical discrepancies). As the amendment was never passed, Congress has set the size of the House of Representatives by statute. Congress regularly increased the size of the House to account for population growth throughout the 19th century until it fixed the number of voting House members at 435 in 1911, where, aside from a temporary increase to 437 members from 1959 through 1962 after Alaska and Hawaii were admitted to the Union, it has remained.
