determines how a ship is
manned and taxed and whether a foreign-owned ship may be placed on the
register.
Internal register - 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, manning by
foreign nationals, 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.
Merchant ship - A vessel that carries goods against payment of
freight; commonly used to denote any nonmilitary ship but accurately
restricted to commercial vessels only.
Register - The record of a ship's ownership and nationality as listed
with the maritime authorities of a country; also, 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.

Money figures: All money figures are expressed in contemporaneous US
dollars unless otherwise indicated.

National product: The total output of goods and services in a country
in a given year. See GDP methodology, Gross domestic product (GDP),
and Gross national product (GNP).

Net migration rate: The balance 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 (3.56 migrants/1,000 population); an
excess of persons leaving the country as net emigration (-9.26
migrants/1,000 population).

Population: Figures are estimates from the Bureau of the Census based
on statistics from population censuses, vital statistics registration
systems, or sample surveys pertaining to the recent past, and on
assumptions about future trends. Starting with the 1993 Factbook,
demographic estimates for some countries (mostly African) have taken
into account the effects of the growing incidence of AIDS infections;
