by having relatively few of the registered ships actually owned in the flag state. Thus, while virtually any flag can be used for ships under a given set of circumstances, an FOC register is one where the majority of the merchant fleet is owned abroad. It is also referred to as an open register. A flag state is the nation in which a ship is registered and which holds legal jurisdiction over operation of the ship, whether at home or abroad. Maritime legislation of the flag state determines how a ship is crewed and taxed and whether a foreign-owned ship may be placed on the register. An internal register is a register of ships maintained as a subset of a national register. Ships on the internal register fly the national flag and have that nationality but are subject to a separate set of maritime rules from those on the main national register. These differences usually include lower taxation of profits, use of foreign nationals as crewmembers, and, usually, ownership outside the flag state (when it functions as an FOC register). The Norwegian International Ship Register and Danish International Ship Register are the most notable examples of an internal register. Both have been instrumental in stemming flight from the national flag to flags of convenience and in attracting foreign-owned ships to the Norwegian and Danish flags. A merchant ship is a vessel that carries goods against payment of freight; it is commonly used to denote any nonmilitary ship but accurately restricted to commercial vessels only. A register is the record of a ship's ownership and nationality as listed with the maritime authorities of a country; also, it is the compendium of such individual ships' registrations. Registration of a ship provides it with a nationality and makes it subject to the laws of the country in which registered (the flag state) regardless of the nationality of the ship's ultimate owner.
Military This category includes the entries dealing with a country's military structure, manpower, and expenditures.
Military branches This entry lists the names of the ground, naval, air, marine, and other defense or security forces.
Military expenditures - dollar figure This entry gives current military expenditures in US dollars; the figure is calculated by multiplying the estimated defense spending in percentage terms by the gross domestic product (GDP) calculated on an exchange rate basis not purchasing power parity (PPP) terms. Dollar figures for military expenditures should be treated with caution because of different price patterns and accounting methods among nations, as well as wide variations in the strength of their currencies.
Military expenditures - percent of GDP This entry gives current military expenditures as an estimated percent of gross domestic product (GDP).
Military manpower - availability This entry gives the total numbers of males and females age 15–49 and assumes that every individual is fit to serve.
Military manpower - fit for military service This entry gives the number of males and females age 15–49 fit for military service. This is a more refined measure of potential military manpower availability which tries to correct for the health situation in the country and reduces the maximum potential number to a more realistic estimate of the actual number fit to serve.
Military manpower - military age This entry gives the minimum age at which an individual may volunteer for military service or be subject to conscription.
Military manpower - reaching military age annually This entry gives the number of draft-age males and females entering the military manpower pool in any given year and is a measure of the availability of draft-age young adults.
Military - note This entry includes miscellaneous military information of significance not included elsewhere.
Money figures All money figures are expressed in contemporaneous US dollars unless otherwise indicated.
National holiday This entry gives the primary national day of celebration - usually independence day.
Nationality This entry provides the identifying terms for citizens - noun and adjective.
Natural Gas - consumption This entry is the total quantity of natural gas consumed in cubic meters. The discrepancy between the quantity of natural gas produced and/or imported and the quantity consumed and/or exported is due to the omission of stock changes and other complicating factors.
Natural Gas - exports This entry is the total quantity of natural gas exported in cubic meters.
Natural Gas - imports This entry is the total quantity of natural gas imported in cubic meters.
Natural Gas - production This entry is the total quantity of natural gas produced in cubic meters. The discrepancy between the quantity of natural gas produced and/or imported and the quantity consumed and/or exported is due to the omission of stock changes and other complicating factors.
Natural Gas - proved reserves This entry is the stock of proved reserves of natural gas in cubic meters (cu. m.). Proved reserves are those quantities of natural gas, which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
Natural hazards
This entry lists potential natural disasters.
Natural resources This entry lists a country's mineral, petroleum, hydropower, and other resources of commercial importance.
Net migration rate This entry includes the figure for the difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (e.g., −9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. High levels of migration can cause problems such as increasing unemployment and potential ethnic strife (if people are coming in) or a reduction in the labor force, perhaps in certain key sectors (if people are leaving).
Oil - consumption This entry is the total oil consumed in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
Oil - exports This entry is the total oil exported in barrels per day (bbl/day), including both crude oil and oil products.
Oil - imports This entry is the total oil imported in barrels per day (bbl/day), including both crude oil and oil products.
Oil - production This entry is the total oil produced in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
Oil - proved reserves This entry is the stock of proved reserves of crude oil in barrels (bbl). Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
People This category includes the entries dealing with the characteristics of the people and their society.
People - note This entry includes miscellaneous demographic information of significance not included elsewhere.
Personal Names - Capitalization The Factbook uses all uppercase letters for personal names by which the subject is usually referred to in various media. An example is President Vicente FOX Quesada of Mexico. Members of royal families are usually referred by other than their family name (King and Prime Minister FAHD bin Abd al-Aziz Al Saud of Saudi Arabia, Queen BEATRIX of the Netherlands, or King PHUMIPHON Adunyadet of Thailand). Some Asians are referred to by the first element of their name - also their surname, such as President NO Muh-hyun of South Korea.
Personal Names - Spelling The romanization of personal names in the Factbook normally follows the same transliteration system used by the US Board on Geographic Names for spelling place names. At times, however, a foreign leader expressly indicates a preference for, or the media or official documents regularly use, a romanized spelling that differs from the transliteration derived from the US Government
