the first apportionment was contained in . after the first census in 1790, congress passed the apportionment act of 1792 and adopted the jefferson method to apportion u.s. representatives to the states based on population. the jefferson method required fractional remainders to be discarded when calculating each state's total number of u.s. representatives and was used until the 1830 census. the webster method, proposed in 1832 by daniel webster and adopted for the 1840 census, allocated an additional representative to states with a fractional remainder greater than 0.5. the hamilton/vinton (largest remainder) method was used from 1850 until 1900. the vinton or hamilton method was shown to be susceptible to an apportionment paradox. the apportionment act of 1911, in addition to setting the number of u.s. representatives at 435, returned to the webster method, which was used following the 1910 and 1930 censuses (no reapportionment was done after the 1920 census). the current method, known as the huntington–hill method or method of equal proportions, was adopted in 1941 for reapportionment based on the 1940 census and beyond. the revised method was necessary in the context of the cap on the number of representatives set in the reapportionment act of 1929.
