 In 2005, after extensive studies of cost of living across the world, The World Bank raised the measure for global poverty line to reflect the observed higher cost of living.Thereafter, the World Bank determined poverty rates from those living on less than US$1.25 per day on 2005 PPP basis, a measure that has been widely used in media and scholarly circles.In May 2014, after revisiting its poverty definition, methodology and economic changes around the world, the World Bank proposed another major revision to PPP calculation methodology, international poverty line and indexing it to 2011 US dollar.
