A bicameral legislature is comprised of two chambers, often described as the lower house and the upper house.

The House of Representatives is referred to as the lower house of the United States Congress, because it has more Members than the Senate.

Established by Article I of the Constitution, the Legislative Branch consists of the House of Representatives and the Senate, which together form the United States Congress.

The upper house in the six states with a bicameral legislature is called the State Legislative Council, or Vidhan Parishad. Members of the former are called MLAs, and those of the latter MLCs.

The Vidhan Sabha is the lower house and corresponds to the Lok Sabha while the Vidhan Parishad is the upper house and corresponds to the Rajya Sabha of the Parliament of India.
