Communications-note: This entry includes miscellaneous communications information of significance not included elsewhere.
Constitution: This entry includes the dates of adoption, revisions, and major amendments.
Country map: Most versions of the Factbook provide a country map in color. The maps were produced from the best information available at the time of preparation. Names and/or boundaries may have changed subsequently.
Country name: This entry includes all forms of the country's name approved by the US Board on Geographic Names (Italy is used as an example): conventional long form (Italian Republic), conventional short form (Italy), local long form (Repubblica Italiana), local short form (Italia), former (Kingdom of Italy), as well as the abbreviation. Also see the Terminology note.
Currency: This entry identifies the national medium of exchange and its basic subunit.
Current issues: This entry at the beginning of a country profile briefly characterizes major geographic, social, political, and military developments in the past 12 months and may include a statement about one or two key future trends. This entry appears for only a few countries at the present time, but may be added to more countries in the future.
Data code: This entry gives the official US Government digraph that precisely identifies every land entity without overlap, duplication, or omission. AF, for example, is the data code for Afghanistan. This two-letter country code is a standardized geopolitical data element promulgated in the Federal Information Processing Standards Publication (FIPS) 10-4 by the National Institute of Standards and Technology at the US Department of Commerce and maintained by the Office of the Geographer and Global Issues at the US Department of State. The data code is used to eliminate confusion and incompatibility in the collection, processing, and dissemination of area-specific data and is particularly useful for interchanging data between databases. Appendix F cross-references various country codes and Appendix G does the same thing for hydrographic codes.
Data codes-country: This information is presented in Appendix F: Cross-Reference List of Country Data Codes which includes the US Government approved Federal Information Processing Standards (FIPS) codes, the International Organization for Standardization (ISO) codes, and Internet codes for land entities.
Data codes-hydrographic: This information is presented in Appendix G: Cross-Reference List of Hydrographic Data Codes which includes the International Hydrographic Organization (IHO) codes, Aeronautical Chart and Information Center (ACIC; now National Imagery and Mapping Agency or NIMA) codes, and Defense Intelligence Agency (DIA) codes for hydrographic entities. The US Government has not yet approved a standard for hydrographic data codes similar to the FIPS 10-4 standard for country data codes.
Dates of information: The information cutoff date was 1 January 1998, although a few important changes after that date have been included. Most demographic statistics are estimates for 1998.
