Kiribati Population and Language

Almost all Kiribati residents are Micronesians. They call themselves and their Austronesian language i-kiribati. English, the official language of the country, is widespread; about one third of the population is bilingual. Nine out of ten Kiribati live in the Tungaru (Gilbert Islands) archipelago, which covers one third of the land area.

Particularly densely populated is the southern part of the “metropolitan atoll” Tarawa, where half of the country’s over 110,000 residents live. Attempts have been made to get people to move to uninhabited islands, but more are instead drawn to Tarawa in search of livelihood.
