# Computing Congressional Apportionment

## Computing Congressional Apportionment

Since that first census in 1790, five methods of apportionment have been used. The current method used, the Method of Equal Proportions, was adopted by congress in 1941 following the census of 1940. This method assigns seats in the House of Representatives according to a "priority" value. The priority value is determined by multiplying the population of a state by a "multiplier."

For example, each of the 50 states is assigned one seat out of the current total of 435. The next, or 51st seat, goes to the state with the highest priority value and thus became that state's second seat. This continues until all 435 seats are assigned to the states.

Equal Proportions Method – P x Multiplier = Priority Value

P - represents a state's total population

n - represents the number of seats a state would have if it gained a seat (because all states automatically received one seat the next seat gained is "seat two," and the next "seat three," and the next "seat four," and so on.).

The multiplier equals:

The higher the Priority Value, the more seats per state.
