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.

2021年的人口与住房普查是自1956年以来在汤加进行的第9次普查，也是统计局进行的第7次普查。人口与住房普查是一项浩大而复杂的工程。无疑，这是我们能想到的最大规模的统计活动，它触及了王国中每一个个体和家庭。普查的结果在生成汤加的官方统计数据以及为衡量可持续发展目标指标提供基本信息方面发挥着重要作用。
2021年汤加人口与住房普查是自五年间隔普查之后的第三次普查。此次普查将提供有关汤加人口规模、分布和结构以及其他社会和经济信息的最新信息。
定期的全国人口与住房普查对于国家的发展政策和规划工作至关重要，因为它代表了大多数国家社会、人口和经济状况的唯一国家快照，以及这些领域近期发展的情况，这些情况影响着其人口的总体福祉。
人口普查为我们提供了一个获得国家人口准确、全面和一致图景的机会。这些结果对于政策制定、规划和资源有效分配至关重要。它为小区域和不同人口群体提供了唯一可直接比较的统计数据来源。它被用作许多统计系列（如人口概况、信息图表和详细的 demographic 分析；人口估计、预测和样本调查框架）的参考基础。
普查日期为2021年11月30日午夜，汤加的所有人均参与了普查，以确保普查不遗漏任何一人。2021年人口与住房普查第1卷是两本详细普查结果统计出版物中的第一本。报告包含详细的统计表格，以方便用户进行更全面的研究和进一步的分析。
