Federal government of the United States Legislative branch
One house is the House of Representatives. The House of Representatives is made up of Representatives, who are each elected by voters from their own state. Every 10 years, the U.S. Census Bureau conducts a census, or count, of the population of the United States. States gain or lose Representatives based on their total population as shown by the census. Representatives serve two-year terms. The total number of representatives today is 435. The leader of the House of Representatives is the Speaker of the House, who is also the person who would become president if the President and Vice President were unable.
