GNI, PPP (constant 2021 international $)

This economic metric quantifies the total income generated by a nation's residents, adjusted for differences in price levels across countries through purchasing power parity (PPP) rates. Unlike nominal measures, this indicator reflects the actual purchasing power of income in terms of goods and services, providing a more accurate representation of economic well-being. By converting gross national income into constant 2017 international dollars, it allows for meaningful comparisons over time and across various economies, factoring in the value added by domestic production, product taxes, and cross-border income flows. This approach enables analysts and policymakers to gauge the true economic health and living standards of populations in a globally interconnected context. Source:
