If a broader definition at USD 2 at PPP/person/day is applied, the poverty rates are significantly higher, with declines from 85% in 1990 to 51% in 2009 (WB WDI, 2012). Thus, even if progress in poverty reduction has been significant, around half of the population remains vulnerable to falling into absolute poverty in case of natural disasters or a deterioration in economic conditions. The share fell for both urban and rural households, but remains much higher for rural households.
