The richest 1% of adults in the world own 40% of the planet's wealth, according to the largest study yet of wealth distribution. The report also finds that those in financial services and the internet sectors predominate among the super rich. Europe, the US and some Asia Pacific nations account for most of the extremely wealthy. More than a third live in the US. Japan accounts for 27% of the total, the UK for 6% and France for 5%. The global study - from the World Institute for Development Economics Research of the United Nations - is the first to chart wealth distribution in every country as opposed to just income, for which more comprehensive date is available. It included all the most significant components of household wealth, including financial assets and debts, land, buildings and other tangible property. Together these total $125 trillion globally. The report found the richest 10% of adults accounted for 85% of the world total of global assets. Half the world's adult population, however, owned barely 1% of global wealth. These levels of inequality are grotesque," said Duncan Green, head of research at Oxfam. "It is impossible to justify such vast wealth when 800 million people go to bed hungry every night."
