NOTES, DEFINITIONS, AND ABBREVIATIONS
There have been some significant changes in this edition. The Trust Territory of the Pacific Islands became the independent nation of Palau. The gross domestic product (GDP) of all countries is now presented on a purchasing power parity (PPP) basis rather than on the old exchange rate basis. There is a new entry on Age structure and the Airports entry now includes unpaved runways. The Communications category has been restructured and now includes the entries of Telephone system, Radio, and Television. The remainder of the entries in the former Communications category-Railroads, Highways, Inland waterways, Pipelines, Ports, Merchant marine, and Airports-can now be found under a new category called Transportation. There is a new appendix listing estimates of gross domestic product on an exchange rate basis for all nations. A reference map of the Republic of South Africa is included. The electronic files used to produce the Factbook have been restructured into a database. As a result, the formats of some entries in this edition have been changed. Additional changes will occur in the 1996 Factbook.
