There are often other rules in addition to this requirement for proportionality. For example, there are five rules governing the election of the House of Representatives in the United States: 1) the number of representatives of a given state cannot decrease where the total number of representatives increases (Alabama paradox), 2) only the quota determines the number of seats to be allocated (rounded up or down to the nearest whole number), 3) all the States are subject to the same method of allocation, 4) the method used must not excessively favour small States over large States, and vice versa, 5) each State must receive at least one representative. Similarly when the 1958 electoral map was drawn up in France, the principle of proportionality was supplemented by the obligation to give each département at least two deputies.
