This document discusses different methods for apportioning congressional seats among US states based on population: Hamilton, Jefferson, Webster, and Hill-Huntington. Hamilton's method allocates remaining seats to states with the largest fractional quotas. Jefferson's method favors larger states by allocating extra seats to those with the largest critical divisors. Webster's method rounds quotas neutrally. Hill-Huntington has been used since 1940, allocating extra seats to states with the largest critical divisors based on geometric means. The best method minimizes differences in representative shares or district populations among states.
