The fifth richest country is this

The UAE has become the world's fifth richest country per capital measured by the value of its built environment according to the latest Global Built Asset Wealth Index published by Arcadis, the leading global Design & Consultancy firm for natural and built assets. The UAE makes up the top five behind Qatar, Singapore, Hong Kong and Japan, with built assets of $140,500 for every citizen.

The index, which was compiled for Arcadis by the Centre for Economics and Business Research (Cebr), calculates the value of all the buildings and infrastructure that contribute to economic productivity in 32 countries, which collectively make up 87 per cent of global GDP.

"The health and wealth of a nation can be measured in many different ways and while factors such as GDP or employment have great value, a prosperous society is underpinned by a well-developed built environment that meets the needs of its people and economy," said Alan Richell, head of Business Advisory in the Middle East at Arcadis. "To date, Dubai alone has built 190 skyscrapers since the millennium and is developing its economic diversification plans even further in sectors such as tourism, financial services and education."

Qatar and Singapore stand comfortably ahead of the pack on built assets per capital, at $198,000 and $192,000 respectively. The countries near the top of this ranking are disproportionately made up of smaller nations, either by population or area, so the density of the built asset stock is much greater per resident. Saudi Arabia, by comparison, has a smaller built asset stock per capital where its built asset wealth is spread among its large and growing population.

Total built asset wealth globally now stands at an estimated $218 trillion, which is the equivalent to $30,700 per person alive today. The stock of built assets is closely correlated with a nation's economic output. On average, countries analyzed have a built asset stock worth 2.9 times GDP. China now has a built asset wealth of $47.6trillion, overtaking the USA which comes in second place with a wealth of $36.8trillion.
