Factbook 2007 is the third edition of a comprehensive and dynamic statistical annual from the OECD. More than 100 indicators cover a wide range of areas: economy, agriculture, education, energy, environment, foreign aid, health and quality of life, industry, information and communications, population/labor force, trade and investment, taxation, public expenditure, and R& D. A dynamic link (STATLink) is provided for each table. The link directs the user to a web page where the corresponding data are available in Excel format. This year the special focus is on international migration, on which the OECD has unique expertise.
