On behalf of the International Comparison Program (ICP) Executive Board and the World Bank, I’d like to thank everyone who’s contributed to the success of the 2011 round. The results are now available in report form, as a data download, and through interactive applications.
The largest global statistical program
The ICP is hosted by the World Bank, and estimates purchasing power parities, or PPPs, for use as currency converters to compare the size and price levels of economies around the world. In terms of geographic scope, implementation time frame and institutional partnerships, many people consider it to be the largest ever global statistical initiative. It’s conducted under the authority of the United Nations Statistical Commission, and the 2011 ICP round collected over 7 million prices from 199 economies in eight regions, with the help of 15 regional and international partners. It’s the most extensive effort to measure PPPs ever undertaken.
Although the World Bank collaborates with international agencies that work with external debt and debt-related statistics (the Bank for International Settlements (BIS), the International Monetary Fund (IMF), the Organisation for Economic Co-operation and Development (OECD) and others), the World Bank has the international mandate to collect external debt data, and we maintain comprehensive external debt information.
On July 1, we updated the analytical country classification, which groups economies of the world into four categories based on 2012 GNI per capita estimates: low income, lower-middle income, upper-middle income, and high income. This has prompted some questions related to the review of this classification scheme, which we announced late last year and for which we solicited and received your feedback. I thought it would be useful to post an update.
