The Country Reports as found in the Political Risk Yearbook contain a wealth of economic and social information about many of the world's most important countries. The reports are particularly useful for understanding the overall suitability for doing business in that country.
Clicking on the link for a country will take you to an archive of reports for that country, sorted by year in descending order.
When you click on a given year, the "full report" for that country is available.
Helpful hint: Older editions may split the reports into parts; check for the length of the document - full documents are typically 50+ pages
