How this figure is calculated

GDP (constant 2015 US$) divided by GDP (current US$), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.

GDP (constant 2015 US$) ÷ GDP (current US$)

Computed from

  • GDP Country official statistics, National Statistical Organizations and/or Central Banks
  • GDP Country official statistics, National Statistical Organizations and/or Central Banks

Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
