The Republic of Indonesia is a country in Southeast Asia and Oceania. It is an archipelago comprising approximately 17,500 islands. With a population of over 238 million people, it is the world’s fourth most populous country. The country shares land borders with Papua New Guinea, East Timor, and Malaysia. Other neighbouring countries include Singapore, Philippines, Australia, Palau, and the Indian territory of the Andaman and Nicobar Islands.
Across its many islands, Indonesia consists of hundreds of distinct native ethnic and linguistic groups. The largest—and politically dominant—ethnic group are the Javanese. A shared identity has developed, defined by a national language, ethnic diversity and religious pluralism within a majority Muslim population. Indonesia’s national motto, “Bhinneka Tunggal Ika” (“Unity in Diversity” literally, “many, yet one”), articulates the diversity that shapes the country.
