Description
|
Subnational poverty headcount ratios were derived from 66 nationally representative household surveys and population census information conducted in various years around 2008 for 26 countries. Our poverty calculations are based on the comparison between the household per-capita consumption expenditure (a synthetic indicator expressing the money-metric welfare utility level) and the $1.90 and $3.10/day poverty lines expressed in international equivalent purchasing power parity (PPP) dollars in 2011. Poverty headcount with standard deviation, gap, severity, and Gini index are also provided. (2016-12-30)

Notes
| It is crucial to stress that poverty distribution are not referred to 2011, but they are referred to the survey year, although they represent poverty headcount measured at an international comparative level, i.e. expressed in value of the same reference year, 2011. In this regard, cross-country poverty comparison should be viewed as comparisons for a given constant purchasing power of the local currency respect to the international benchmark, rather than for a given point in time. The PPP factor has a significant impact on the poverty measures obtained, and the recent release of the 2011 PPP numbers by the World Bank ICP program significantly changed the relative poverty among countries with respect to the estimates based on the 2005 PPP, although the overall trend of global poverty is confirmed (see Ferreira et al., 2015 and Jolliffe & Prydz, 2015 for a discussion of the importance of the PPP factor). This work was undertaken as part of the CGIAR Research Program on Policies, Institutions, and Markets (PIM) led by the International Food Policy Research Institute (IFPRI). Funding support was provided by PIM and the Bill and Melinda Gates Foundation. |
