The IWI looks beyond the traditional economic and
development yardsticks of Gross Domestic Product (GDP) and the Human
Development Index (HDI) to include a full range of assets such as manufactured,
human and natural capital, showing the true state of a nation's
wealth and the sustainability of its growth. It aims to show whether we are building or destroying the productive base that supports
our well being.
Some country examples:
Australia has an annual GDP growth rate of 2.2% over the
last 19 years, but an IWI of only 0.1%.
China – GDP 9.6%, IWI 2.1%
US – GDP 1.8%, IWI 0.7%
