To obtain several countries’ statistical data from each country sources are inefficient, and those data are usually not comparable because of deference of survey methodology/frequency, language, units, and others. International organizations, such as United Nations or OECD, arrange each country’s primary social and economic statistical data in a similar format and provide them at their statistical information web site. In addition, several Japanese sources, such as the Statistics Bureau of Japan or JETRO, arrange that information and offer international comparable statistical data.
