\details{
  The Penn World Table provides purchasing power parity and
  national income accounts converted to international prices for 189
  countries/territories for some or all of the years 1950--2009. The European Union
  or the OECD provide more detailed purchasing power and real product
  estimates for their countries and the World Bank makes current price
  estimates for most PWT countries at the GDP level.

  This version contains data from PWT version 7.0. As far as possible the
  original data from PWT has been preserved. For example, percentages
  have been maintained rather than converted to fractions.

  China is contained in two versions. For all details see the official
  documentation.
