Tuvalu is a constitutional monarchy operating within the framework of a parliamentary democracy, where the British monarch serves as the Head of State, represented locally by a Governor-General. The head of government is the Prime Minister, who is elected by the members of the unicameral Parliament, known as the Fale i Fono. This legislative body consists of 15 members elected for four-year terms from eight island constituencies. Political parties do not exist in the formal sense; instead, elections and parliamentary governance are based on personal alliances, family ties, and island loyalties. The legal system is derived from English common law and local statutory law, with the High Court of Tuvalu serving as the superior court of record, exercising jurisdiction over constitutional matters and serious civil and criminal cases.

The administrative geography of the nation is divided into nine districts, corresponding to the nine inhabited islands and atolls: Nanumea, Nui, Niutao, Nanumaga, Vaitupu, Nukufetau, Funafuti, Nukulaelae, and Niulakita. Each of these islands maintains a local government council, known as a Kaupule, which operates under the Falekaupule Act. The Falekaupule is the traditional assembly of elders on each island, wielding significant influence over local social and developmental affairs. Funafuti serves as the capital and the main administrative center, hosting the majority of government buildings, the national hospital, and the country's only international airport. This decentralized administrative structure ensures that traditional island authority remains integrated with the modern bureaucratic requirements of the state.

The national economy is characterized by a heavy reliance on external revenue sources, primarily the Tuvalu Trust Fund, which was established in 1987 by international donors including Australia, New Zealand, and the United Kingdom. This fund is managed by an international board and provides annual drawdowns to supplement the national budget, helping to finance infrastructure, education, and health services. Domestically, the economy is dominated by the public sector, which employs a significant portion of the formal workforce. The private sector remains small, consisting largely of retail wholesalers and small-scale service providers. The official currency is the Australian dollar, though Tuvaluan coins are minted and used alongside Australian banknotes for local transactions.
