The book and the accompanying website presents empirical data on long-run economic, social and political trends for a sample of twenty-nine developing countries, representing Asia, Latin America and Africa. These twenty-nine countries represent more than three quarters of the total population of developing countries in the year 2000. The book contains over seventy tables, covering the period since 1950, sometimes going back to the pre-war period. The country data are supplemented by aggregate statistics for different regions and continents. 

This website makes the tables of the book available to students in the form of excel files. The first sheet of each table is the table from the book, the subsequent sheets present the raw data from which the table has been constructed and the operations performed on these raw data.
