SHF—super—high—frequency; any radio frequency in the 3,000- to 30,000-MHz range
SHF—super-high-frequency; any radio frequency in the 3,000- to 30,000-MHz range
Solidaridad-geosynchronous satellites in Mexico's system of international telecommunications in the Western Hemisphere
Statsionar—Russia's geostationary system for satellite telecommunications
submarine cable—a cable designed for service under water
TAT—Trans—Atlantic Telephone; any of a number of high—capacity submarine coaxial telephone cables linking Europe with North America
telefax—facsimile service between subscriber stations via the public switched telephone network or the international Datel network
telegraph—a telecommunications system designed for unmodulated electric impulse transmission
telex—a communication service involving teletypewriters connected by wire through automatic exchanges
tropospheric scatter—a form of microwave radio transmission in which the troposphere is used to scatter and reflect a fraction of the incident radio waves back to earth; powerful, highly directional antennas are used to transmit and receive the microwave signals; reliable over-the-horizon communications are realized for distances up to 600 miles in a single hop; additional hops can extend the range of this system for very long distances
trunk network—a network of switching centers, connected by multichannel trunk lines
UHF—ultra-high-frequency; any radio frequency in the 300- to 3,000-MHz range
VHF—very-high-frequency; any radio frequency in the 30- to 300-MHz range
Telephones: This entry gives the total number of subscribers.
Television broadcast stations: This entry gives the total number of separate broadcast stations plus any repeater stations.
Televisions: This entry gives the total number of television sets.
Terminology: Due to the highly structured nature of the Factbook database, some collective generic terms have to be used. "Country name" and "National capital", for example are used collectively to include nations, dependent areas, uninhabited islands, areas of special sovereignty, etc. The term "Military" is also used as an umbrella term for various civil defense, security, and defense activities.
Terrain: This entry contains a brief description of the topography.
Total fertility rate: This entry gives a figure for the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the capacity of the families to educate their children.
Transnational Issues: This category includes only two entries at the present time. Disputes—international and Illicit drugs—deal with current issues going beyond national boundaries.
Transportation: This category includes the entries dealing with the movement of people or material.
Transportation—note: This entry includes miscellaneous transportation information of significance not included elsewhere.
Unemployment rate: This entry contains the percent of the labor force that is without jobs. Substantial underemployment might be noted.
United Nations System: This information is presented in Appendix B: United Nations System which is a chart, table, or text (depending on the version of the Factbook) that shows the organization of the UN in detail.
Waterways: This entry gives the total length and individual names of navigable rivers, canals, and other inland bodies of water.
Weights and measures: This information is presented in Appendix E: Weights and Measures which includes mathematical notations (mathematical powers and names), metric interrelationships (prefix; symbol; length, weight, or capacity; area; volume), and standard conversion factors.
Years: All year references are for the calendar year (CY) unless indicated as fiscal year (FY). The calendar year is an accounting period of 12 months from 1 January to 31 December. The fiscal year is an accounting period of 12 months other than 1 January to 31 December. FY93/94 refers to the fiscal year that began in calendar year 1993 and ended in calendar year 1994.
Note: Information for the US and US dependencies was compiled from material in the public domain and does not represent Intelligence Community estimates. The [2]Handbook of International Economic Statistics, published annually in September by the Central Intelligence Agency, contains detailed economic information for the Organization for Economic Cooperation and Development (OECD) countries, the successor nations to the Soviet Union, and selected other countries. The Handbook can be obtained wherever the Factbook is available.
