About the International Comparison Program (ICP)

The International Comparison Program (ICP) is one of the largest, and most enduring, statistical initiatives in the world. It is managed by the World Bank under the auspices of the United Nations Statistical Commission (UNSC), and relies on a partnership of international, regional, sub-regional, and national agencies working under a robust governance framework and following an established statistical methodology. At its forty-seventh session, in March 2016, the UNSC instituted the ICP as a permanent element of the global statistical programme.

ICP’s main objectives are (i) to produce purchasing power parities (PPPs) and comparable price level indexes (PLIs) for participating economies; and (ii) to convert volume and per capita measures of gross domestic product (GDP) and its expenditure components into a common currency using PPPs.
