Why does national data for the MPI date from so many different years? Isn’t it unfair to compare countries if the statistics in one case are five years older than in another?
The MPI relies on the most recent and reliable data available since 2000. However surveys are taken in different years, and some countries do not have recent data. Sixty four countries’ data comes from 2005 or later; thirty countries are from 2003 or 2004, and ten countries from 2000-2002. The difference in dates limits direct cross country comparisons, as circumstances may have improved, or deteriorated, in the intervening years.
