Unicameralism in the context of "Assembly of French Polynesia"

The barrios of Puerto Rico are the third-level administrative divisions defined with geographic boundaries serving as the primary legal subdivisions of the 78 municipalities in the archipelago and island of Puerto Rico, an unincorporated territory of the U.S. Amounting to 902 wards or boroughs equivalent to minor civil divisions in the U.S., like cities, townships, and parishes, barrios are under the governmental authority of the popularly elected strong mayor and unicameral legislature governing the municipality within which they are located. Barrios are subdivided into numerous subbarrios, districts, communities, and/or sectors.

Except for San Juan, Ponce, Florida, and Vieques, all municipalities have a barrio equivalent to a downtown area in the U.S. called pueblo, officially known as barrio-pueblo (literally "neighborhood-town"), which typically is the site of the historic Spanish colonial settlement, administrative center, and urban core of the municipality. Of the 902 barrios proper, 828 are barrios and 74 barrios-pueblos.

Bicameralism is a type of legislature that is divided into two separate assemblies, chambers, or houses, known as a bicameral legislature. Bicameralism is distinguished from unicameralism, in which all members deliberate and vote as a single group. As of 2022, roughly 40% of the world's national legislatures are bicameral, while unicameralism represents 60% nationally and much more at the subnational level.

Often, the members of the two chambers are elected or selected by different methods, which vary from jurisdiction to jurisdiction. This can often lead to the two chambers having very different compositions of members.

An upper house is one of two chambers of a bicameral legislature, the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. A legislature composed of only one house (and which therefore has neither an upper house nor a lower house) is described as unicameral.

The municipalities of Puerto Rico (Spanish: municipios de Puerto Rico) are second-level administrative divisions defined with geographic boundaries and governmental authority in the archipelago and island of Puerto Rico, an unincorporated territory of the U.S. Amounting to 78 incorporated towns and cities equivalent to U.S. counties, two of which are outside the main island, namely the smaller islands of Vieques and Culebra, the municipalities are governed by a popularly elected strong mayor and unicameral legislature. They are subdivided into 902 barrios, third-level divisions controlled by the municipal government. As a jurisdiction under U.S. sovereignty, Puerto Rico does not have first-level administrative units akin to states or provinces.

The municipalities of Puerto Rico operate under the Municipal Code of Puerto Rico (Law. No. 107 of 2020), which superseded the Autonomous Municipalities Act of Puerto Rico (Law No. 81 of 1991), as established by the Legislative Assembly of Puerto Rico, the governmental body responsible for their organization under Section 1, Article VI of the Constitution of Puerto Rico. Electorally, the municipalities are grouped into eight senatorial districts and forty representative districts, representing roughly equal populations in the Legislative Assembly.

The government of Puerto Rico encompasses the local administrative structure of the archipelago and island of Puerto Rico, an unincorporated territory of the U.S. organized under the Constitution of Puerto Rico since its establishment as the Commonwealth of Puerto Rico in 1952. The government is a republican democracy divided into three branches: the law-implementing executive, the law-making legislative, and the law-interpreting judicial. The Governor is the chief executive, the Legislative Assembly is the legislature, and the Supreme Court is the highest court of the territory, which is divided into 78 municipalities, each one headed by a strong mayor and a unicameral legislature. Like U.S. states and other U.S. territories, Puerto Rico is subject to the sovereign jurisdiction of the U.S. federal government.

With the American annexation of Puerto Rico during the Spanish–American War, the U.S. established a military government to administer the unincorporated territory from 1898 to 1900, when it was replaced by a civil insular government organized under the organic acts of the Foraker Act from 1900 to 1917 and the Jones–Shafroth Act from 1917 to 1952. The Constitution of Puerto Rico established the Commonwealth of Puerto Rico and its government under the continued status of unincorporated territory in 1952. With the ratification of the constitution, the full authority and responsibility for the local administration of Puerto Rico was vested in the residents of Puerto Rico, resulting in complete self-governance within the archipelago and island.

The Parliament of England was the legislature of the Kingdom of England from the 13th century until 1707 when it was replaced by the Parliament of Great Britain. Parliament evolved from the great council of bishops and peers that advised the English monarch. Great councils were first called Parliaments during the reign of Henry III (r. 1216–1272). By this time, the king required Parliament's consent to levy taxation.

Originally a unicameral body, a bicameral Parliament emerged when its membership was divided into the House of Lords and House of Commons, which included knights of the shire and burgesses. During Henry IV's reign, the role of Parliament expanded beyond the determination of taxation policy to include the right to petition, which essentially enabled English citizens to petition the body to address complaints in their local towns and counties. By this time, citizens were given the power to vote to elect their representatives—the burgesses—to the House of Commons.

Grand National Assembly of Turkey is the unicameral legislative branch of the Turkish government. It is the sole body given the legislative prerogatives by the unitary Turkish Constitution.

The government of New York City, headquartered at New York City Hall in Lower Manhattan, is organized under the New York City Charter and provides for a mayor-council system. The mayor is elected to a four-year term and is responsible for the administration of city government. The New York City Council is a unicameral body consisting of 51 members, each elected from a geographic district, normally for four-year terms. Primary elections for local offices use ranked choice voting, while general elections use plurality voting. All elected officials are subject to a two consecutive-term limit. The court system consists of two citywide courts and three statewide courts.

New York City's government employs approximately 330,000 people, more than any other city in the United States and more than any U.S. state but three: California, Texas, and New York. The city government is responsible for public education, correctional institutions, public safety, recreational facilities, sanitation, water supply, and welfare services.

The Grand and General Council (Italian: Consiglio Grande e Generale; Romagnol: Grând e Gnèral Cunsèj) is the unicameral parliament of San Marino. The council has 60 members elected for a five-year term.
