Each row compares both countries in the same year: the latest year for which both have a figure.
Newer figures set aside so that both countries are compared in the same year: Thailand's Gini Index, 33.3 in 2024.
A tick (✓) marks the more favorable figure where the better direction is widely agreed: higher GDP per person, growth and life expectancy; lower unemployment, government debt, inequality (Gini index) and CO₂ emissions per person. GDP and population measure size, fertility has no single better level, and both very high and very low inflation cause problems, so those rows are not scored.
IMF projection: a forecast from the IMF World Economic Outlook, revised at each release, not a measured value.

Why sources report different numbers
The IMF, World Bank and United Nations each publish GDP figures on their own schedule. When their numbers differ, the main reason is usually that they describe different years. The comparison table above uses the IMF figures.
| Source | Vietnam | Thailand |
|---|---|---|
| IMF | $542.13B2026 (IMF projection) | $599.12B2026 (IMF projection) |
| World Bank | $514.70B2025 | $577.01B2025 |
| United Nations | $476.39B2024 | $526.52B2024 |
These figures differ mainly because each source reports a different year: the IMF for 2026 (a projection), the World Bank for 2025 and the United Nations for 2024. Each is the latest that source has published. From lowest to highest, Vietnam's figures are about 14% apart and Thailand's figures are about 14% apart.
