    Abstract

    This report is the first of its kind to be prepared using data collected by the Statistics Department (SD) on the impact of a cyclone in Tonga. Tropical Cyclone Gita hit the main island of Tongatapu and the island of ‘Eua on the night of Monday, 12th February 2018 as a destructive category 4 storm, causing severe damages to these two islands which consists of about 80% of the Total population of Tonga.

    The Statistics Department were tasked to undertake a consolidated household survey to all the households in Tongatapu and ‘Eua for a post-disaster needs assessment. Such information were used by different clusters to assist with their assistance to the people affected within areas of health, education, shelter, social protection and others.

    *post-disaster needs assessment based on the information required by the clusters responsible for responding to the cyclone within different thematic areas.

    There have been challenges faced by the Statistic Department during the process of this post-disaster needs assessment which identifies the following areas: Data needs must be clearly identified so that SD can objectively design the questions to capture the required information. Also, some of the respondents were not providing the correct information and therefore led to grievances when households receive aid or beneficiaries from government.
