  • Data collection is a relatively high-level exercise; therefore not all details are captured.
  • Different countries use different concepts. Hence the development of a single set of definitions encounters difficulty in matching the various concepts. Consequently, in a number of specific cases, the position of a country in a certain group might be debatable.
