Like most Pacific Island countries, Tonga is vulnerable to external economic shocks and natural disasters, particularly droughts and cyclones. Tonga ranks third on a global ranking of 111 development countries by the Composite Vulnerability Index. Tongas resident population is approximately 100,000 and is almost entirely Polynesian. The same number of Tongans is believed to reside in overseas countries, mainly in New Zealand, Australia and the United States of America.
