The 2008 CIA World Factbook

School life expectancy (primary to tertiary): School life expectancy (SLE) is the total number of years of schooling (primary to tertiary) that a child can expect to receive, assuming that the probability of his or her being enrolled in school at any particular future age is equal to the current enrollment ratio at that age. Caution must be maintained when utilizing this indicator in international comparisons. For example, a year or grade completed in one country is not necessarily the same in terms of educational content or quality as a year or grade completed in another country. SLE represents the expected number of years of schooling that will be completed, including years spent repeating one or more grades.

Sex ratio: This entry includes the number of males for each female in five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually, it could cause unrest among young adult males who are unable to find partners.

Stock of direct foreign investment - abroad: This entry gives the cumulative US dollar value of all investments in foreign countries made directly by residents - primarily companies - of the home country, as of the end of the time period indicated. Direct investment excludes investment through purchase of shares.

Stock of direct foreign investment - at home: This entry gives the cumulative US dollar value of all investments in the home country made directly by residents - primarily companies - of other countries as of the end of the time period indicated.

Stock of money: This entry, also known as "M1," comprises the total quantity of currency in circulation (notes and coins) plus demand deposits denominated in the national currency, held by nonbank financial institutions, state and local governments, nonfinancial public enterprises, and the private sector of the economy. The national currency units have been converted to US dollars at the closing exchange rate on the date of the information.

Stock of quasi money: This entry comprises the total quantity of time and savings deposits denominated in the national currency, held by nonbank financial institutions, state and local governments, nonfinancial public enterprises, and the private sector of the economy. When added together with "M1" the total money supply is known as "M2." The national currency units have been converted to US dollars at the closing exchange rate on the date of the information.

Suffrage: This entry gives the age at enfranchisement and whether the right to vote is universal or restricted.

Telephone numbers: All telephone numbers in The World Factbook consist of the country code in brackets, the city or area code (where required) in parentheses, and the local number. The one component that is not presented is the international access code, which varies from country to country. For example, an international direct dial telephone call placed from the US to Madrid, Spain, would be as follows: 011 [34] (1) 577-xxxx, where 011 is the international access code for station-to- station calls; 01 is for calls other than station-to-station calls, [34] is the country code for Spain, (1) is the city code for Madrid, 577 is the local exchange, and xxxx is the local telephone number. An international direct dial telephone call placed from another country to the US would be as follows: international access code + [1] (202) 939- xxxx, where [ 1] is the country code for the US, (202) is the area code for Washington, DC, 939 is the local exchange, and xxxx is the local telephone number.
