I have tried to find how accurate this information is.If you wanted to know what the "official" figure is for the present world population, where would you access that? No doubt, you would probably google it on the internet.
Google is making a big change to how it displays results in its dominant search engine. It is rolling out a new feature called the Knowledge Graph which breaks from the traditional practice of matching keywords with webpages.
According to an article on Blog Tips about Google's Knowledge Graph, immediate answers or "facts" from pre-selected sources like the CIA Factbook, Wikipedia, and the World Bank will be provided in search results along side the organic results:
Instead of using the typical search strength of a particular answer, this new feature will draw 'facts' from places like Wikipedia for historical information, CIA World Factbook for geopolitical answers, the World Bank for economic facts, Freebase for information about people and other predetermined sources.
This move by Google seems eerily similar to Orwell's Ministry of Truth in that search results, or "answers and facts", will no longer be gathered based on the algorithmic popularity of content, but rather selected by Google.
Worldometers says:"The above world population clock is based on the estimates of the United Nations and will show the same number wherever you are in the world and whatever time you set on your PC. Worldometers is the only website to show live counters that are based on UN data available for free from Microsoft®. This symbol indicates a link to a non-government website. Our linking to these sites does not constitute an endorsement of any products, services or the information found on them."
I mean there's the electronic world population clock - which is a program meant to estimate the present World Population. It is derived mostly by the CIA - The CIA Factbook, IMF, UN, UNICEF, USG. The U.N. depends on foreign governments of developing nations to provide that information. But how accurate is it? Are there incentives in place (i.e. foreign aid) that would persuade government leaders of developing nations to give false/misleading information?
Four Things to Remember
In trying to understand the CIA, there are four things to keep in mind:
First, when we talk about the CIA, we should recognize that the conversation is about all secret U.S. government agencies, with the CIA only used as an example. There may be secret agencies that the public doesn't know exist.
Second, the problems discussed here seem to come only from one department of the CIA, the department that supports secret action. The other main department of the CIA collects information. There don't seem to be problems with collection of information.
Third, we should realize that a huge amount of money is spent to keep the secret agencies secret. There have been articles in U.S. newspapers that said that the CIA sometimes puts false information into U.S. newspapers because the agency wants to mislead foreign intelligence agencies.
It is often important, when reading a sentence like this, to cut off the word "because" and everything after it. Obviously, if secret agencies are allowed to put lies in public news, then they are allowed to lie about why they are doing it. Any organization that is allowed to lie cannot be trusted to tell the truth. For this reason, it is difficult to get accurate information about the secret agencies. That doesn't mean that we shouldn't think about them, however.
An example of the CIA mis-leading the public that pays its bills is the CIA World Factbook [cia.gov]. Click on the Country Listing for Afghanistan on the left. Under Background, the CIA makes no mention of its own involvement in fighting a war in that country. The CIA World Factbook is often used by people with no political involvement to check facts about other countries. It is not copyrighted because U.S. taxpayers pay to have it written and updated.
Fourth, we should realize that, in the final analysis, it doesn't matter that we don't know exactly what the CIA has actually done. The most important issue is that we are not allowed to know. The United States is a democracy and citizens cannot do their democratic duty of making choices if they don't know the facts. Is democracy a better form of government, or isn't it? If it is, then secrecy about matters affecting policy should not be allowed. SOURCE
