What is Tax revenue (% of GDP)?

Tax revenue (% of GDP), measured in %, measures the total economic output of Tonga. It represents the broadest indicator of economic activity, capturing production, income, and expenditure across all sectors — from manufacturing and services to agriculture and government. GDP can be calculated three ways: by adding up all expenditures (consumption + investment + government spending + net exports), by summing all incomes earned, or by totaling value added at each production stage. In Tonga, the statistical agency compiles GDP data through comprehensive surveys of businesses, government records, and household expenditure patterns. While GDP per capita provides insight into average living standards, it does not capture income distribution, environmental costs, or unpaid work like caregiving. Nevertheless, GDP growth remains the most widely followed metric for assessing whether an economy is expanding or contracting.
