Municipalities in Cagayan Valley

A municipality is a local government made up of barangays, led by a mayor, a vice mayor and the Sangguniang Bayan, the municipal council.^[1] Only Congress can create one, by law, approved in a plebiscite. The law asks for an income of ₱2.5 million a year, 25,000 people and 50 km² of land.^[1]

A municipality that grows can become a component city by law, once it earns ₱100 million a year and has 100 km² of land or 150,000 people.^{[1, 2]}

How it fits

Cities and municipalities are the local governments of the towns, each led by a mayor, a vice mayor and a council, and each made up of barangays. A municipality becomes a city by a law of Congress, once it earns enough and has enough people or land.
