Revenue, excluding grants (% of GDP)

Government Revenue (as a Percentage of GDP)

Government revenue (as a percentage of GDP) is the ratio of total government revenue obtained from sources such as taxes and social insurance contributions divided by that country's Gross Domestic Product (GDP). This indicator is an important measure showing the extent to which a government secures fiscal revenue relative to the country's overall economic scale. It is generally expressed as "Revenue, excluding grants," with foreign aid and donations excluded.

There are several reasons why this indicator is important. First, it allows measurement of a government's fiscal self-sufficiency. The higher the revenue, the more independently a government can operate its finances without relying on external assistance. Second, it serves as an indicator for understanding the tax burden weight in a country. A higher GDP ratio means the nation's citizens bear a relatively heavier tax burden. Third, by comparing with government expenditures, it becomes the basis for determining the soundness of the fiscal balance and is essential for evaluating the sustainability of deficits or surpluses.

As a general trend, developed countries typically have government revenue-to-GDP ratios of around 25-40%, while developing countries tend to range from 10-20%. This is because developed countries have well-established social security systems requiring higher revenues. Key points to note include that revenue often declines during economic crises, making it important to observe correlations with economic conditions. Additionally, policy changes such as tax reforms or increases in social insurance contributions have significant impacts, and time-series comparative analysis can reveal the direction of a country's fiscal policy.
