A new UNDP report has said that humanity remains deeply unequal despite impressive progress and a sustained reduction in inequality requires a shift to more inclusive growth patterns supported by redistributive polices and changes in social norm.
The report, titled 'Humanity Divided: Confronting Inequality in Developing Countries' and released Wednesday by the organisation's administrator Helen Clark, said that the richest one per cent of the world population owns about 40% of the world's assets while the bottom half owns no more than one percent.
"The report explores the causes and consequences of the inequalities which divide us -- within and between countries -- and argues that there is nothing inevitable about growing inequality," Clark said in a statement.
Income inequality after adjusting for population size increased by 11% in developing countries between 1990 and 2010.
More than 75% of the population is living today in societies where income is more unequally distributed than it was in the 1990s, the report said.
The report stated that high inequality undermines development by hindering economic progress, weakening democratic life and threatening social cohesion.
