Why is South Tarawa one of the most densely populated areas in the Pacific?

South Tarawa is one of the most densely populated areas in the Pacific primarily due to significant internal migration from other islands to this urban center. While the population on most of Kiribati's islands has remained relatively static, more than two-fifths of the country's total population now resides in South Tarawa.1

This concentration is driven by South Tarawa's role as the nation's primary commercial, educational, and administrative hub. It houses national government headquarters, port facilities, and an extension center of the University of the South Pacific, which attract residents seeking employment and services. Consequently, this migration pattern has resulted in an extremely high population density within the limited land area of the atoll's islets.21
