PovcalNet is a web-based interactive computational tool that
can be used to estimate the extent of absolute poverty in the
world, replicating calculations made by the World Bank. The tool also
enables users to calculate poverty measures under different
assumptions (such as different poverty lines or Purchasing Power
Parity values) and to assemble the estimates using various
country groupings. PovcalNet does real-time calculations from an
annually updated database.
