A lower house is one of two chambers of a bicameral legislature, the other chamber being the upper house. Despite its official position "below" the upper house, in many legislatures worldwide, the lower house has come to wield more power or otherwise exert significant political influence. The lower house typically is the larger of the two chambers, meaning its members are more numerous.
In comparison with the upper house, lower houses frequently display certain characteristics (though they vary per jurisdiction).
The government of the day is usually required to present its budget to the lower house, which must approve the budget. It is a widespread practice for revenue (appropriation) bills to originate in the lower house. A notable exception to this is the West Virginia House of Delegates, which allows revenue bills to originate from either house.
