Notes, Definitions, and Abbreviations
There have been some significant changes in this edition. In the Goverment section the former Branches entry has been replaced by three entries—Executive branch, Legislative branch, and Judicial branch. The Leaders entry now has subentries for Chief of State, Head of Government, and their deputies. The Elections entry has been completely redone with information for each branch of the national government, including the date for the last election, the date for the next election, results (percent of vote by candidate or party), and current distribution of seats by party. In the Economy section there is a new entry on Illicit drugs.
