Notes, Definitions, and Abbreviations (continued)
Contributors: Information was provided by the Bureau of the Census (Department of Commerce), Central Intelligence Agency, Defense Intelligence Agency, Defense Nuclear Agency, Department of State, Foreign Broadcast Information Service, Navy Operational Intelligence Center and Maritime Administration (merchant marine data), Office of Territorial and International Affairs (Department of the Interior), United States Board on Geographic Names, United States Coast Guard, and others.
Dates of information: In general, information available as of 1 January 1990 was used in the preparation of this edition. Population figures are estimates for 1 July 1990, with population growth rates estimated for mid-1990 through mid-1991. Major political events have been updated through 30 March 1990. Military age figures are average annual estimates for 1990–94.
Death rate: The average annual number of deaths during a year per 1,000 population at midyear. Also known as crude death rate.
Diplomatic representation: The US Government has diplomatic relations with 162 nations. There are only 144 US embassies, since some nations have US ambassadors accredited to them, but no physical US mission exists. The US has diplomatic relations with 149 of the 159 UN members—the exceptions are Albania, Angola, Byelorussia (constituent republic of the Soviet Union), Cambodia, Cuba, Iran, Vietnam, People's Democratic Republic of Yemen [Yemen (Aden) or South Yemen], Ukraine (constituent republic of the Soviet Union), and, obviously, the US itself. In addition, the US has diplomatic relations with 13 nations that are not in the UN—Andorra, Federated States of Micronesia, Kiribati, Liechtenstein, Marshall Islands, Monaco, Nauru, San Marino, South Korea, Switzerland, Tonga, Tuvalu, and the Vatican City. North Korea is not in the UN and the US does not have diplomatic relations with that nation. The US has not recognized the incorporation of Estonia, Latvia, and Lithuania into the Soviet Union and continues to accredit the diplomatic representatives of their last free governments.
Disputes: This category includes a wide variety of situations that range from traditional bilateral boundary disputes to unilateral claims of one sort or another. Every international land boundary dispute in the “Guide to International Boundaries,” a map published by the Department of State, is included. References to other situations may also be included that are border- or frontier-relevant, such as maritime disputes, geopolitical questions, or irredentist issues. However, inclusion does not necessarily constitute official acceptance or recognition by the US Government.
Entities: Some of the nations, dependent areas, areas of special sovereignty, and governments included in this publication are not independent, and others are not officially recognized by the US Government. Nation refers to a people politically organized into a sovereign state with a definite territory. Dependent area refers to a broad category of political entities that are associated in some way with a nation. Names used for page headings are usually the short-form names as approved by the US Board on Geographic Names. The long-form name is included in the Government section and an entry of “none” indicates a long-form name does not exist. In some instances, no short-form name exists—then the long-form name must serve for all usages.
