Economic growth and human development have advanced remarkably, but this progress often comes at the expense of degrading and overexploiting natural resources, raising critical questions about its sustainability. Is today¡¯s growth jeopardizing the wellbeing of future generations?
Gross domestic product (GDP) has long been the primary measure of economic performance. While it effectively captures the production of goods and services, GDP does not account for natural resource depletion, environmental damage, or the long-term costs of growth. It also overlooks the value of critical natural assets such as clean air, water, forests, and ecosystems.
The World Bank¡¯s Changing Wealth of Nations (CWON) program addresses these limitations by providing the most comprehensive and rigorous wealth
database available today. Unlike GDP, CWON measures wealth¡ªa nation¡¯s ability to sustain economic progress over time¡ªby encompassing produced capital, such as factories and infrastructure; natural capital, including forests and fossil fuel reserves; human capital, which reflects education and health; and net foreign assets. By monitoring real wealth per capita, CWON assesses whether economic growth is achieved by expanding or depleting a country¡¯s productive base. Sustained increases in wealth per capita ensure that future generations inherit the same or greater opportunities for production and consumption.
As a pioneering effort in wealth measurement, CWON produces a publicly accessible and methodologically rigorous database, built on internationally endorsed principles from the and the . This ensures its comparability with other economic metrics like GDP, providing policymakers and researchers with vital insights into the sustainability of economic progress.
Global wealth is predominantly concentrated in high-income countries.
In 2020, high-income countries held over two-thirds of global wealth in nominal terms, despite a 15 percent decline in their share since 1995. Meanwhile, the wealth gap has narrowed significantly for upper- and lower-middle-income countries, whose combined share of global wealth has doubled, rising from 15 percent in 1995 to over a quarter in 2020. However, low-income and lower-middle-income countries, which are home to half of the world's population, account for only 7 percent of global wealth. Notably, there is little evidence of the wealth gap closing for low-income countries, as their share has remained below 1 percent since 1995, in stark contrast to the progress seen in middle-income countries.
