The term length for the U.S. House of Representatives is two years, with elections held every even year. The House has a representative for every congressional district in the United States. Each district represents about 700,000 people.
In Congress' other house, the Senate, members are elected every six years. Elections are staggered over even years. Every state has two senators, regardless of the state's population.
The majority party in the House has significant power to schedule bills for debate and voting. Debate is typically limited and legislation is passed in one business day. In the Senate, a single member can delay legislation from going to a floor vote. Debate is not finished until 60 senators vote to submit a bill for consideration.
