The democratic voting system of Congress seeks proportionality in one house and equity in the other.
In this way, the house of representatives elects the parliamentarians according to the proportionality of the demographic density of the states. The more populous states elect more deputies and the less populous states, elect less.
However, in the Senate each state elects an equal number of senators, matching the interests of the states. This is because the senate is a place that represents the states, while the house of representatives represents the people.
So members of the house of representatives are elected on the basis of the state's population at the most recent U.S. census, but each state has an equal number of senators.
