Abstract
The Population and Housing Census 2021 was the 9th census carried out in Tonga since 1956, and the 7th census conducted by the Statistics Department. The Population and Housing Census is a vast and complex undertaking. It is certainly the largest statistical exercise we can contemplate, touching, as it does, every individual and household in the Kingdom. The result of the census has an important role in producing official statistics for Tonga and providing fundamental information for measuring SDG indicators.
The 2021 Tonga Population and Housing Census is the third census undertaken following the 5-year interval census. This census will provide up-to-date information regarding the size, distribution, and structure of the Tonga population as well as other social and economic information.
Periodic national population and housing census are critical to countries' development policy and planning efforts, in that they represent from most countries' only national snapshot of its social, demographic, and economic conditions, as well as information on recent developments in these areas, that impact on the overall well-being of its population.
