Total Fertility Rate: The number of children a woman would have in her lifetime assuming current age-specific birth rates remain constant throughout her childbearing years (usually considered to be ages 15 to 49).
Contraceptive Use: The percentage of currently married or �in-union� women of reproductive age (15�49) who are currently using any form of contraception. �Total� use includes modern and traditional methods. �Modern� methods include clinic and supply methods such as the pill, injectables, implants, IUD, condom, and sterilization. Data refer to the latest survey year through 2001. Data prior to 1995 are shown in italics.

Maternal Deaths: The number of deaths to women per 100,000 live births that result from conditions related to pregnancy, delivery, and related complications. The estimates for most less developed countries are taken from 1995 consensus estimates of WHO, UNICEF, and UNFPA.

Percent Enrolled in Secondary School: The ratio of the number of students enrolled in secondary school to the population in the applicable age group (such as 12 to 17 years of age) for the country (gross enrollment ratio). It can exceed 100 when the number of students actually enrolled exceeds the population of the relevant age group. Data refer to the latest survey year from 1993-1997. Data from 1990�1992 are shown in italics.

GNI PPP per Capita (US$): GNI PPP per capita is 1999 Gross National Income in purchasing power parity (PPP) divided by midyear population.

World and regional totals are weighted averages of countries for which data are available; regional averages are shown when data or estimates are available for at least three-quarters of the region�s population. Regional totals may include small countries not shown.
