How Reapportionment Works
Reapportionment is the process of distributing seats in a legislative body among constituencies based on population. Different mathematical methods can produce different results:
Jefferson Method
Uses a divisor that is adjusted downward until the total seats equal the target. Tends to favor larger states.
Webster Method
Uses a divisor that rounds quotas to the nearest whole number. Considered more neutral than other methods.
Huntington-Hill Method
Currently used for U.S. House of Representatives. Uses a geometric mean for rounding that minimizes relative differences.
