Via World Bank – “PovcalNet is an interactive computational tool that allows you to replicate the calculations made by the World Bank’s researchers in estimating the extent of absolute poverty in the world. PovcalNet also allows you to calculate the poverty measures under different assumptions and to assemble the estimates using alternative country groupings or for any set of individual countries of the user’s choosing. PovcalNet is self-contained; it has reliable built-in software that quickly does the relevant calculations for you from the built-in database.   In October 2015, the World Bank released estimates of global poverty from 1981 to 2012 based on 2011 PPP. The new poverty estimates combine Purchasing Power Parity (PPP) exchange rates for household consumption from the 2011 International Comparison Program with data from more than one thousand household surveys across 131 developing countries, and 21 high income countries. Over two million randomly sampled households were interviewed for the 2012 estimate, representing 87 percent of the population of the developing world. PovcalNet is the source of, and allows users to replicate, the Bank’s official global, regional and internationally comparable country level poverty estimates published in the World Development Indicators, as well as the shared prosperity indices reported in the Global Monitoring Report…”
