legislative Apportionment

Apportionment, legislative, distribution of voters' representation in the lawmaking bodies. Representation can be apportioned according to population or political units. For example, although each U.S. state, whatever size, elects 2 senators, the number of seats each state holds in the House of Representatives is based on the state's population. There is a reapportionment of seats each decade when the census is taken.
