The Philippines, officially known as the Republic of the Philippines, is a sovereign island country in Southeast Asia situated in the western Pacific Ocean. To its north across the Luzon Strait lies Taiwan; west across the South China Sea sits Vietnam; southwest is the island of Borneo across the Sulu Sea, and to the south the Celebes Sea separates it from other islands of Indonesia; while to the east it is bounded by the Philippine Sea and the island-nation of Palau. Its location on the Pacific Ring of Fireand close to the equator make the Philippines prone to earthquakes and typhoons, but also endows it with abundant natural resources and some of the world's greatest biodiversity. At 300,000 square kilometers, the Philippines is the 73rd-largest country in the world, consisting of an archipelago of 7,107 islands that are categorized broadly under three main geographical divisions: Luzon, Visayas, and Mindanao. Its capital city is Manila while its most populous city is Quezon City. With a population of more than 98 million people, the Philippines is the seventh-most populated country in Asia and the 12th most populated country in the world. An additional 12 million Filipinos live overseas, comprising one of the world's largest and most influential diasporas. Multiple ethnicitiesand cultures are found throughout the islands. In prehistoric times, Negritos were some of the archipelago's earliest inhabitants. They were followed by successive waves of Austronesian peoples who brought with them influences from Malay, Hindu, and Islamic societies. Various nations were established under the rule of Datus, Rajahs, Sultans or Lakans. Trade with China also introduced Chinese culture and settlement, which remain present to this day.
