that does not meet concessional terms. Aid is considered to have been committed when agreements are initialed by the parties involved and constitute a formal declaration of intent.

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.

Exchange rate: The value of a nation's monetary unit at a given date or over a given period of time, as expressed in units of local currency per US dollar and as determined by international market forces or official fiat.

Gross domestic product (GDP): The value of all final goods and services produced within a nation in a given year.

Gross national product (GNP): The value of all final goods and services produced within a nation in a given year, plus income earned abroad, minus income earned by foreigners from domestic production.

Gross world product (GWP): The aggregate value of all goods and services produced worldwide in a given year.

GNP/GDP methodology: In the "Economy" section, GNP/GDP dollar estimates for the great majority of countries are derived from purchasing power parity (PPP) calculations rather than from conversions at official currency exchange rates. The PPP method normally involves the use of international dollar price weights, which are applied to the quantities of goods and services produced in a given economy. In addition to the lack of reliable data from the majority of countries, the statistician faces a major difficulty in specifying, identifying, and allowing for the quality of goods and services. The division of a GNP/GDP estimate in local currency by the corresponding PPP estimate in dollars gives the PPP conversion rate. On average, one thousand dollars will buy the same market basket of goods in the US as one thousand dollars—converted to the local currency at the PPP conversion rate—will buy in the other country. Whereas PPP estimates for OECD countries are quite reliable, PPP estimates for developing countries are often rough approximations. The latter estimates are based on extrapolation of numbers published by the UN International Comparison Program and by Professors Robert Summers and Alan Heston of the University of Pennsylvania and their colleagues. Because currency exchange rates depend on a variety of international and domestic financial forces that often have little relation to domestic output, use of these rates is less satisfactory for calculating GNP/GDP than the PPP method. In developing countries with weak currencies the exchange rate estimate of GNP/GDP in dollars is typically one- fourth to one-half the PPP estimate. Furthermore, exchange rates may suddenly go up or down by 10% or more because of market forces or official fiat whereas real output has remained unchanged. On 12 January 1994, for example, the 14 countries of the African Financial Community (whose currencies are tied to the French franc) devalued their currencies by 50%. This move, of course, did not cut the real output of these countries by half. One additional caution: the proportion of, say, defense expenditures as a percent of GNP/GDP in local currency accounts may differ substantially from the proportion when GNP/GDP accounts are expressed in PPP terms, as, for example, when an observer estimates the dollar level of Russian or Japanese military expenditures;

Growth rate (population): The annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative.

Illicit drugs: There are five categories of illicit drugs—narcotics, stimulants, depressants (sedatives), hallucinogens, and cannabis. These categories include many drugs legally produced and prescribed by doctors as well as those illegally produced and sold outside medical channels.

Cannabis (Cannabis sativa) is the common hemp plant, which provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer), tetrahydrocannabinol (THC, Marinol), hashish (hash), and hashish oil (hash oil).

Coca (Erythroxylon coca) is a bush, and the leaves contain the stimulant cocaine. Coca is not to be confused with cocoa, which comes from cacao seeds and is used in making chocolate, cocoa, and cocoa butter.

Cocaine is a stimulant derived from the leaves of the coca bush.

Depressants (sedatives) are drugs that reduce tension and anxiety and include chloral hydrate, barbiturates (Amytal, Nembutal, Seconal, phenobarbital), benzodiazepines (Librium, Valium), methaqualone (Quaalude), glutethimide (Doriden), and others (Equanil, Placidyl, Valmid).

Drugs are any chemical substances that effect a physical, mental, emotional, or behavioral change in an individual.

Drug abuse is the use of any licit or illicit chemical substance that results in physical, mental, emotional, or behavioral impairment in an individual.

Hallucinogens are drugs that affect sensation, thinking, self-awareness, and emotion. Hallucinogens include LSD (acid,
