Ports and harbors This entry lists the major ports and harbors selected on the basis of overall importance to each country. This is determined by evaluating a number of factors (e.g., dollar value of goods handled, gross tonnage, facilities, military significance).
Radio broadcast stations This entry includes the total number of AM, FM, and shortwave broadcast stations.
Railways This entry states the total route length of the railway network and of its component parts by gauge: broad, dual, narrow, standard, and other.
Reference maps
This section includes world and regional maps.
Religions This entry includes a rank ordering of religions by adherents starting with the largest group and sometimes includes the percent of total population.
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.
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 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.
