Round each state's natural quota down to the nearest whole number; temporarily give each state this number of seats.
Assign the remaining seats (one at a time) to the states whose natural quotas have the largest fractional parts.
Lowndes's Method
Calculate the natural quota for each state.
Round each state's natural quota down to the nearest whole number; temporarily give each state this number of seats.
Assign the remaining seats (one at a time) to the states whose natural quotas have the largest relative fractional parts.
Jefferson's Method
Find a divisor such that when each state's modified quota is rounded down, the correct number of seats has been distributed.
Threshold divisor for n seats under Jefferson's Method =
State¢s populationn
Webster's Method
Find a divisor such that when each state's modified quota is rounded naturally, the correct number of seats has been distributed.
Threshold divisor for n seats under Webster's Method =
State¢s populationn-0.5
Hill-Huntington Method
Find a divisor such that when each state's modified quota is rounded according to the Hill-Huntington rounding rules, the correct number of seats has been distributed.
Hill-Huntington rounding rules: If a state's quota falls between the whole numbers and n, the cutoff point for rounding is
H =
_____ Ö(n-1)n.
If the quota is below H, it is rounded down; otherwise, it is rounded up.
Threshold divisor for n seats under the Hill-Huntington Method =
