Saint Laguë

Saint Laguë Method in Constitutional Law

From the Comparative Constitutions Project: The SainteLaguë method of the highest average (also known as Webster’s method or divisor method with standard rounding) is one way of allocating seats proportionally for representative assemblies with party list voting systems. The SainteLaguë method is a divisor method, like the d’Hondt method, but with a different divisor. After all the votes have been tallied, successive quotients are calculated for each list. The formula for the quotient is V/(2S+1), where V is the total number of votes that list received, and S is the number of seats that party has been allocated so far, initially 0 for all parties. Whichever list has the highest quotient gets the next seat allocated, and their quotient is recalculated given their new seat total. The process is repeated until all seats have been allocated.
