the CIA Web site, Chiefs of State is updated weekly, but the last update for the Factbook was an earlier date. Why the discrepancy?
Although Chiefs of State and The World Factbook both appear on the CIA Web site, they are produced and updated on different weekly schedules. Chiefs of State includes fewer countries but more leaders, whereas The World Factbook has a much larger database and includes all countries.
Some percentage distributions do not add to 100. Why not?
Because of rounding, percentage distributions do not always add precisely to 100%. Rounding of numbers always results in a loss of precision - i.e., error. This error becomes apparent when percentage data are totaled, as the following two examples show:
Original Data Rounded to whole integer
Example 1 43.2 43
30.4 30
26.4 26
———
100.0 99
Example 2 42.8 43
31.6 32
25.6 26
———
100.0 101
When this occurs, we do not force the numbers to add exactly to 100, because doing so would introduce additional error into the distribution.
What rounding convention does The World Factbook use?
In deciding on the number of digits to present, the Factbook staff assesses the accuracy of the original data and the needs of US Government officials. All of the economic data are processed by computer - either at the source or by the Factbook staff. The economic data presented in The Factbook, therefore, follow the rounding convention used by virtually all numerical software applications, namely, any digit followed by a "5" is rounded up to the next higher digit, no matter whether the original digit is even or odd. Thus, for example, when rounded to the nearest integer, 2.5 becomes 3, rather than 2, as occurred in some pre-computer rounding systems.
Why do you list "Independence" dates for countries such as France,
Germany, and the United Kingdom?
For most countries, this entry presents the date that sovereignty was achieved and from which nation, empire, or trusteeship. For other countries, the date may be some other significant nationhood event such as the traditional founding date or the date of unification, federation, confederation, establishment, or state succession and so may not strictly be an "Independence" date. Dependent entities have the nature of their dependency status noted in this same entry.
Technical ::
Does The World Factbook comply with Section 508 of the
Rehabilitation Act regarding accessibility of Web pages?
The World Factbook home page has a link entitled "Text/Low Bandwidth Version." The country data in the text version is fully accessible. We believe The World Factbook is compliant with the Section 508 law. If you are experiencing difficulty, please use our comment form to provide us details of the specific problem you are experiencing and the assistive software and/or hardware you are using so that we can work with our technical support staff to find and implement a solution. We welcome visitors' suggestions to improve accessibility of The World Factbook and the CIA Web site.
I am using the Factbook online and it is not working. What is wrong?
Hundreds of "Factbook" look-alikes exist on the Internet. You can access The World Factbook at: www.cia.gov, which is the only official site.
When I attempt to download a PDF (Portable Document Format) map file (or some other map) the file has no image. Can you fix this?
Some of the files on The World Factbook Web site are large and could take several minutes to download on a dial-up connection. The screen might be blank during the download process.
When I open a map on The World Factbook site, it is fuzzy or granular, or too big or too small. Why?
Adjusting the resolution setting on your monitor should correct this problem.
Is The World Factbook country data available in machine-readable format? All I can find is HTML, but I'm looking for simple tabular data.
The Factbook Web site now features Country Comparison pages for selected Factbook entries. All of the Country Comparison pages can be downloaded as tab-delimited data files that can be opened in other applications such as spreadsheets and databases.

@Afghanistan (South Asia)
Introduction ::Afghanistan
Background:
Ahmad Shah DURRANI unified the Pashtun tribes and founded Afghanistan in 1747. The country served as a buffer between the British and Russian Empires until it won independence from notional British control in 1919. A brief experiment in democracy ended in a 1973 coup and a 1978 Communist counter-coup. The Soviet Union invaded in 1979 to support the tottering Afghan Communist regime, touching off a long and destructive war. The USSR withdrew in 1989 under relentless pressure by internationally supported anti-Communist mujahedin rebels. A series of subsequent civil wars saw Kabul finally fall in 1996 to the Taliban, a hardline Pakistani-sponsored movement that emerged in 1994 to end the country's civil war and anarchy. Following the 11 September 2001 terrorist attacks in New York City and Washington, D.C., a US, Allied, and anti-Taliban Northern Alliance military action toppled the Taliban for sheltering Osama BIN LADIN. The UN-sponsored Bonn Conference in 2001 established a process for political reconstruction that included the adoption of a new constitution, a presidential election in 2004, and National Assembly elections in 2005. In December 2004, Hamid KARZAI became the first democratically elected president of Afghanistan and the National Assembly was inaugurated the following December. Karzai was re-elected in August 2009 for a second term. Despite gains toward building a stable central government, a resurgent Taliban and continuing provincial instability - particularly in the south and the east - remain serious challenges for the Afghan Government.
