About :: History
A Brief History of Basic Intelligence and The World Factbook
The Intelligence Cycle is the process by which information is acquired, converted into intelligence, and made available to policymakers. Information is raw data from any source, data that may be fragmentary, contradictory, unreliable, ambiguous, deceptive, or wrong. Intelligence is information that has been collected, integrated, evaluated, analyzed, and interpreted. Finished intelligence is the final product of the Intelligence Cycle ready to be delivered to the policymaker.
The three types of finished intelligence are: basic, current, and estimative. Basic intelligence provides the fundamental and factual reference material on a country or issue. Current intelligence reports on new developments. Estimative intelligence judges probable outcomes. The three are mutually supportive: basic intelligence is the foundation on which the other two are constructed; current intelligence continually updates the inventory of knowledge; and estimative intelligence revises overall interpretations of country and issue prospects for guidance of basic and current intelligence. The World Factbook, The President's Daily Brief, and the National Intelligence Estimates are examples of the three types of finished intelligence.
The United States has carried on foreign intelligence activities since the days of George Washington but only since World War II have they been coordinated on a government-wide basis. Three programs have highlighted the development of coordinated basic intelligence since that time: (1) the Joint Army Navy Intelligence Studies (JANIS), (2) the National Intelligence Survey (NIS), and (3)The World Factbook .
During World War II, intelligence consumers realized that the production of basic intelligence by different components of the US Government resulted in a great duplication of effort and conflicting information. The Japanese attack on Pearl Harbor in 1941 brought home to leaders in Congress and the executive branch the need for integrating departmental reports to national policymakers. Detailed and coordinated information was needed not only on such major powers as Germany and Japan, but also on places of little previous interest. In the Pacific Theater, for example, the Navy and Marines had to launch amphibious operations against many islands about which information was unconfirmed or nonexistent. Intelligence authorities resolved that the United States should never again be caught unprepared.
In 1943, Gen. George B. Strong (G-2), Adm. H. C. Train (Office of Naval Intelligence - ONI), and Gen. William J. Donovan (Director of the Office of Strategic Services - OSS) decided that a joint effort should be initiated. A steering committee was appointed on 27 April 1943 that recommended the formation of a Joint Intelligence Study Publishing Board to assemble, edit, coordinate, and publish the Joint Army Navy Intelligence Studies (JANIS). JANIS was the first interdepartmental basic intelligence program to fulfill the needs of the US Government for an authoritative and coordinated appraisal of strategic basic intelligence. Between April 1943 and July 1947, the board published 34 JANIS studies. JANIS performed well in the war effort, and numerous letters of commendation were received, including a statement from Adm. Forrest Sherman, Chief of Staff, Pacific Ocean Areas, which said, "JANIS has become the indispensable reference work for the shore-based planners."
The need for more comprehensive basic intelligence in the postwar world was well expressed in 1946 by George S. Pettee, a noted author on national security. He wrote in The Future of American Secret Intelligence (Infantry Journal Press, 1946, page 46) that world leadership in peace requires even more elaborate intelligence than in war. "The conduct of peace involves all countries, all human activities - not just the enemy and his war production."
The Central Intelligence Agency was established on 26 July 1947 and officially began operating on 18 September 1947. Effective 1 October 1947, the Director of Central Intelligence assumed operational responsibility for JANIS. On 13 January 1948, the National Security Council issued Intelligence Directive (NSCID) No. 3, which authorized the National Intelligence Survey (NIS) program as a peacetime replacement for the wartime JANIS program. Before adequate NIS country sections could be produced, government agencies had to develop more comprehensive gazetteers and better maps. The US Board on Geographic Names (BGN) compiled the names; the Department of the Interior produced the gazetteers; and CIA produced the maps.
The Hoover Commission's Clark Committee, set up in 1954 to study the structure and administration of the CIA, reported to Congress in 1955 that: "The National Intelligence Survey is an invaluable publication which provides the essential elements of basic intelligence on all areas of the world. There will always be a continuing requirement for keeping the Survey up-to-date." The Factbook was created as an annual summary and update to the encyclopedic NIS studies. The first classified Factbook was published in August 1962, and the first unclassified version was published in June 1971. The NIS program was terminated in 1973 except for the Factbook, map, and gazetteer components. The 1975 Factbook was the first to be made available to the public with sales through the US Government Printing Office (GPO). The Factbook was first made available on the Internet in June 1997. The year 2010 marks the 63rd anniversary of the establishment of the Central Intelligence Agency and the 67th year of continuous basic intelligence support to the US Government by The World Factbook and its two predecessor programs.

Frequently Asked Questions(by category)
Answers to many frequently asked questions (FAQs) are explained in the Definitions and Notes section inThe World Factbook. Please review this section to see if your question is already answered there. In addition, we have compiled the following list of FAQs to answer other common questions.
General ::
Can you provide additional information for a specific country?
The staff cannot provide data beyond what appears in The World Factbook. The format and information in the Factbook are tailored to the specific requirements of US Government officials and content is focused on their current and anticipated needs. The staff welcomes suggestions for new entries.
How often is The World Factbook updated?
Formerly our Web site and the published Factbook were only updated annually. In November 2001, we began more frequent online updating and for many years bi-weekly updates were the norm. In late 2010 we began to update the online Factbook on a weekly schedule. The CIA discontinued publishing the printed Factbook after the 2007 edition; subsequent annual editions have been published by the US Government Printing Office.
Can I use some or all of The World Factbook for my Web site (book, research project, homework, etc.)?
The World Factbook is in the public domain and may be used freely by anyone at anytime without seeking permission. However, US Code (Section 403m) prohibits use of the CIA seal in a manner which implies that the CIA approved, endorsed, or authorized such use. For any questions about your intended use, you should consult with legal counsel. Further information on use of The World Factbook is described on the Contributors and Copyright Information page. As a courtesy, please cite The World Factbook when used.
Why are there discrepancies between The World Factbook's demographic statistics and other sources?
Although estimates and projections start with the same basic data from censuses, surveys, and registration systems, final estimates and projections can differ as a result of factors including data availability, assessment, and methods and protocols.
Data availability Researchers may obtain specific country data at different times. Estimates or projections developed before the results of a census have been released will not be as accurate as those that take into account new census results.
Assessment Researchers can differ in their assessment of data quality and in their estimates based on the available country data. They often need to adjust their estimates due to such factors as undercounting in a census or underregistration of births or deaths.
Methods and protocols Differences in methods and protocols can shape the way estimates and projections are made of fertility, mortality, and international migration, and how these data are integrated with the population data. For example, the US Census Bureau uses a model that projects the population ahead by single years of age, a single year at a time (population statistics used in the Factbook are based on this model), whereas the United Nations model projects five-year age groups forward, five years at a time.
Why doesn't The World Factbook include information on states, departments, provinces, etc., for each country?
The World Factbook provides national-level information on countries, territories, and dependencies, but not subnational administrative units within a country. A comprehensive encyclopedia might be a source for state/province-level information.
Is it possible to access older editions of The World Factbook to do comparative research and trend analysis?
Previous editions of the Factbook , beginning with 2000, are available for downloading - but not browsing - on the CIA Web site. Rehosted versions of earlier editions of the Factbook are available for browsing, as well as for downloading, at other Internet web sites. We urge caution, however, in attempting to create time series by stringing together economic data - especially dollar values - from previous editions of the Factbook . Over time, data sources, definitions, and economic accounting methods have changed. We occasionally have made these changes ourselves in order to provide our readers with the best information available. Also, in the case of dollar values, changes in relative exchange rates and prices may make trends difficult to comprehend. Therefore, individuals should consult additional resources when doing comparative research or trend analysis.
Would it be possible to set up a partnership or collaboration between the producers of The World Factbook and other organizations or individuals?
The World Factbook does not partner with other organizations or individuals, but we do welcome comments and suggestions that such groups or persons choose to provide.
Geography ::
Why can't I find a geographic name for a particular country?
The World Factbook is not a gazetteer (a dictionary or index of places, usually with descriptive or statistical information) and cannot provide more than the names of the administrative divisions (in the Government category) and major cities/towns (on the country maps). Our expanded Cross-Reference List of Geographic Names (Appendix F), however, includes many of the world's major geographic features as well as historic (former) names of countries and cities mentioned in The World Factbook.
Why are Taiwan and the European Union listed out of alphabetical order at the end of the Factbook entries?
Taiwan is listed after the A-Z country entries because even though the mainland People's Republic of China claims Taiwan, elected Taiwanese authorities de facto administer the island and reject mainland sovereignty claims. With the establishment of diplomatic relations with China on January 1, 1979, the US Government recognized the People's Republic of China as the sole legal government of China, acknowledging the Chinese position that there is only one China and that Taiwan is part of China.
The European Union (EU) is not a country, but it has taken on many nation-like attributes and these may be expanded in the future. A more complete explanation on the inclusion of the EU into the Factbook can be found in the Preliminary statement.
Since we have an ambassador who represents the US at the Vatican, why is this entity not listed in the Factbook?
Vatican City is found under Holy See. The term "Holy See" refers to the authority and sovereignty vested in the Pope and his advisors to direct the worldwide Catholic Church. As the jurisdictional equal of a state, the Holy See can enter into treaties and sends and receives diplomatic representatives. Vatican City, created in 1929 to administer properties belonging to the Holy See in Rome, is recognized under international law as a sovereign state, but it does not send or receive diplomatic representatives. Consequently, Holy See is included as a Factbook entry, with Vatican City cross-referenced in the Geographic Names appendix.
Why is Palestine not listed in The World Factbook?
The Palestinian areas of Gaza Strip and West Bank are listed in the
Factbook.
Why are the Golan Heights not shown as part of Israel or Northern
Cyprus with Turkey?
Territorial occupations/annexations not recognized by the United
States Government are not shown on US Government maps.
Why don't you include information on entities such as Tibet or
Kashmir?
The World Factbook provides information on the administrative divisions of a country as recommended by the United States Board on Geographic Names (BGN). The BGN is a component of the US Government that develops policies, principles, and procedures governing the spelling, use, and application of geographic names - domestic, foreign, Antarctic, and undersea. Its decisions enable all departments and agencies of the US Government to have access to uniform names of geographic features.
Also included in the Factbook are entries on parts of the world whose status has not yet been resolved (e.g., West Bank, Spratly Islands). Specific regions within a country or areas in dispute among countries are not covered.
What do you mean when you say that a country is "doubly landlocked"?
A doubly landlocked country is one that is separated from an ocean or an ocean-accessible sea by two intervening countries. Uzbekistan and Liechtenstein are the only countries that fit this definition.
Why is the area of the United States described as "slightly larger than China" in the Factbook , while other sources list China as larger in area than the United States?
It all depends on whether one is looking at total area (land and water) when making the comparison (which is the criterion used by the Factbook) or just land area (which excludes inland water features such as rivers and lakes).
Total area (combining land and water)
United States = 9,826,630 sq km China = 9,596,960 sq km
Land only (without any water features)
United States = 9,161,923 sq km China = 9,326,410 sq km
Why has The World Factbook dropped the four French departments of
Guadeloupe, Martinique, Reunion, and French Guiana?
The four entities are no longer in The World Factbook because their status has changed. While they are overseas departments of France, they are also now recognized as French regions, having equal status to the 22 metropolitan regions that make up European France. In other words, they are now recognized as being part of France proper. Their status is somewhat analogous to Alaska and Hawaii vis-a-vis the contiguous United States. Although separated from the larger geographic entity, they are still considered to be an integral part of it.
Photos ::
Why do you not have pictures for every country?
Inclusion of photos in The World Factbook is a new feature that premiered with the unveiling of the redesigned online World Factbook in June 2009. This is a long-term project, and we plan to continuously add more photos to the site over time. Eventually, we hope to have images for every country in the Factbook.
Could you include photos of people from different locations around the world?
Factbook policy is to not include photos showing identifiable individuals.
I have great travel photos from my trips abroad. Can I submit them to your website to enhance your photo collection?
We appreciate the many offers from the public to contribute to our photo collection. However, we only use photos from US Government sources.
Spelling and Pronunciation ::
Why is the spelling of proper names such as rulers, presidents, and prime ministers in The World Factbook different than their spelling in my country?
The Factbook staff applies the names and spellings from the Chiefs of State link on the CIA Web site. The World Factbook is prepared using the standard American English computer keyboard and does not use any special characters, symbols, or most diacritical markings in its spellings. Surnames are always spelled with capital letters; they may appear first in some cultures.
Why does the spelling of geographic names, features, cities, administrative divisions, etc. in the Factbook differ from those used in my country?
The United States Board on Geographic Names (BGN) recommends and approves names and spellings. The BGN is the component of the United States Government that develops policies, principles, and procedures governing the spelling, use, and application of geographic names - domestic, foreign, Antarctic, and undersea. Its decisions enable all departments and agencies of the US Government to use uniform names of geographic features. (A note is usually included where changes may have occurred but have not yet been approved by the BGN). The World Factbook is prepared using the standard American English computer keyboard and does not use any special characters, symbols, or most diacritical markings in its spellings.
Why does The World Factbook omit pronunciations of country or leader names?
There are too many variations in pronunciation among English-speaking countries, not to mention English renditions of non-English names, for pronunciations to be included. American English pronunciations are included for some countries such as Qatar and Kiribati.
Why is the name of the Labour party misspelled?
When American and British spellings of common English words differ, The World Factbook always uses the American spelling, even when these common words form part of a proper name in British English.
Policies and Procedures ::
What is The World Factbook's source for a specific subject field?
The Factbook staff uses many different sources to publish what we judge are the most reliable and consistent data for any particular category. Space considerations preclude a listing of these various sources.
The names of some geographic features provided in the Factbook differ from those used in other publications. For example, in Asia the Factbook has Burma as the country name, but in other publications Myanmar is used; also, the Factbook uses Sea of Japan whereas other publications label it East Sea. What is your policy on naming geographic features?
The Factbook staff follows the guidance of the United States Board on Geographic Names (BGN). The BGN is the component of the United States Government that develops policies, principles, and procedures governing the spelling, use, and application of geographic names - domestic, foreign, Antarctic, and undersea. Its decisions enable all departments and agencies of the US Government to have access to uniform names of geographic features. The position of the BGN is that the names Burma and Sea of Japan be used in official US Government maps and publications.
Why is most of the statistical information in the Factbook given in metric units, rather than the units standard to US measure?
US Federal agencies are required by the Metric Conversion Act of 1975 (Public Law 94–168) and by Executive Order 12770 of July 1991 to use the International System of Units, commonly referred to as the metric system or SI. In addition, the metric system is used by over 95 percent of the world's population.
Why don't you include information on minimum and maximum temperature extremes?
The Factbook staff judges that this information would only be useful for some (generally smaller) countries. Larger countries can have large temperature extremes that do not represent the landmass as a whole.
What information sources are used for the country flags?
Flag designs used in The World Factbook are based on various national and vexillological sources.
Why do your GDP (Gross Domestic Product) statistics differ from other sources?
We have two sets of GDP dollar estimates in The World Factbook , one derived from purchasing power parity (PPP) calculations and the other derived from official exchange rates (OER). Other sources probably use one of the two. See the Definitions and Notes section on GDP and GDP methodology for more information.
On 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.
