Notes:
Population mid-1997:The total population (in millions) as of mid-1997. Estimates are based upon a recent census or official data or UN and U.S. Census Bureau projections.

Population in 2025: The projected population (in millions) for 2025, based upon official country projections, or upon series issued by the UN, the U.S. Census Bureau, or PRB projections. Estimates are calculated based on assumptions about the future course of fertility, mortality, and migration.

Percent Urban: Percentage of the total population living in areas termed urban by that country. Typically, the population living in towns of 2,000 or more or in national and provincial capitals are classified as urban.

Total Fertility Rate (TFR): The average number of children a woman will have, assuming that current age-specific birth rates will remain constant throughout her child-bearing years (usually considered to be ages 15-49).

Life Expectancy at Birth: The average number of years a newborn infant can expect to live under current mortality levels.

Percent Literate: The percentage of the population that is literate, given for males (m) and females (f).

GNP per capita: The Gross National Product in $U.S., which includes the value of all domestic and foreign output. Estimates are from the World Bank Atlas, 1997.
