Going beyond traditional measures such as GDP (Gross Domestic Product), the report available to the media uses wealth to monitor countries’ economic progress and sustainability.

“The Changing Wealth of Nations 2018″ tracks the wealth of 141 countries between 1995 and 2014 by aggregating natural capital (such as forests and minerals), human capital (earnings over a person’s lifetime); produced capital (buildings, infrastructure, etc.) and net foreign assets.

Human capital was the largest component of wealth overall while natural capital made up nearly half of wealth in low-income countries, the report said.

Jim Yong Kim, World Bank Group President, said “by building and fostering human and natural capital, countries around the world can bolster wealth and grow stronger. The World Bank Group is accelerating its effort to help countries invest more – and more effectively – in their people.”

“There cannot be sustained and reliable development if we don’t consider human capital as the largest component of the wealth of nations.”

The report found that global wealth grew an estimated 66 per cent from $690 trillion to $1,143 trillion in constant 2014 U.S. dollars at market prices. But inequality was substantial, as wealth per capita in high-income OECD (Organisation for Economic Cooperation and Development) countries was 52 times greater than in low-income countries.

A decline in per capita wealth was recorded in several large low-income countries, some carbon-rich countries in the Middle East, and a few high-income OECD countries affected by the 2009 financial crisis.

It said declining per capita wealth implies that assets critical for generating future income may be depleted, a fact not often reflected in national GDP growth figures.

The report found that more than two dozen low-income countries, where natural capital dominated overall wealth in 1995, moved to middle-income status over the last two decades, in part by investing earnings from natural capital into sectors such as infrastructure, as well as education and health which increase human capital.

While investments in human as well as produced capital are essential, getting rich is not about liquidating natural capital to build other assets, the report notes.

Natural capital per person in OECD countries is three times higher than in low-income countries, even though the share of natural capital in total wealth is just 3 percent in OECD countries.

“Growth will be short-term if it is based on depleting natural capital such as forests and fisheries. What our research has shown is that the value of natural capital per person tends to rise with income. This contradicts traditional wisdom that development necessarily entails depletion of natural resources,’’ said Karin Kemper, Senior Director, Environment and Natural Resources Global Practice at the World Bank.
