Context paragraphs:
California State Assembly: The California State Assembly is the lower house of the California State Legislature.  It consists of 80 members, with each member representing at least 465,000 people.  Due to the state's large population and relatively small legislature, the State Assembly has the largest population-per-representative ratio of any state lower house and second largest of any legislative lower house in the United States after the federal House of Representatives.  As a result of Proposition 140 in 1990 and Proposition 28 in 2012, members elected to the legislature prior to 2012 are restricted by term limits to three two-year terms (six years), while those elected in or after 2012 are allowed to serve 12 years in the legislature in any combination of four-year state senate or two-year state assembly terms.

Gender equality in Rwanda: Gender equality in Rwanda was rated by the World Economic Forum as being sixth-best in the world in 2015.  After the 1994 genocide, Rwanda has promoted gender equality.  The progress of promoting gender equality in Rwanda is driven by a strong commitment from the central government.  Rwanda was the first country in the world to have women occupy over half of the seats in its national legislature.  In 2015, 61.3% of Rwanda's Lower House of Parliament were women, the highest proportion anywhere in the world, and one of only two such bodies where women were in the majority, the other being Bolivia's Lower House of Parliament.  Though the number of females in the Parliament is large, women are still under-represented in other political institutions.

Parliament of South Australia: The Parliament of South Australia at Parliament House, Adelaide is the bicameral legislature of the Australian state of South Australia.

Sejm: The Sejm of the Republic of Poland ( ; Polish: "Sejm Rzeczypospolitej Polskiej" ) is the lower house of the Polish parliament.  It consists of 460 deputies (posłowie, literally "envoys", in Polish) elected by universal ballot and is presided over by a speaker called the "Marshal of the "Sejm" of the Republic of Poland" ("Marszałek Sejmu Rzeczypospolitej Polskiej").  In the Kingdom of Poland, ""Sejm"" referred to the entire three-chamber parliament of Poland, comprising the lower house (the Chamber of Envoys; Polish: "Izba Poselska" ), the upper house (the Senate; Polish: "Senat") and the King.  It was thus a three-estate parliament.  Since the Second Polish Republic (1918–1939), ""Sejm"" has referred only to the lower house of the parliament; the upper house is called the "Senat Rzeczypospolitej Polskiej" ("Senate of the Republic of Poland").

Member of Parliament, Lok Sabha: A Member of Parliament of Lok Sabha (Hindi: सांसद, लोक सभा ) (abbreviated: MP) is the representative of the Indian people to the Lok Sabha; the lower house of the Parliament of India.  Members of Parliament of Lok Sabha are chosen by direct elections on the basis of the adult suffrage.

New South Wales Legislative Council: The New South Wales Legislative Council, or upper house, is one of the two chambers of the parliament of the Australian state of New South Wales.  The other is the Legislative Assembly.  Both sit at Parliament House in the state capital, Sydney.  The Assembly is referred to as the lower house and the Council as the upper house.  It is normal for legislation to be first deliberated on and enacted in the lower house, and then considered in the upper house, which acts in the main as a house of review.  The Council has 42 members, elected by proportional representation in which the whole state is treated as a single electorate.  Members serve eight-year terms, which are staggered so that half the Council is up for election every four years—roughly coinciding with elections to the Legislative Assembly.

Total number of members of Rajya Sabha are lesser than Member of Parliament of the Lok Sabha and have more restricted power than the lower house (Lok Sabha).  Unlike membership to the Lok Sabha, membership to the Rajya Sabha is permanent for a term of six years cannot be dissolved at any time.
