How does a country count the population?

Every 10 years, for the US at least, the government sends out a questionaire to every house in America.  It asks you to fill out things such as number of residents, income, etc.  This gives the government most of the important information about the country.\n\nHowever, this clearly mis-represents two types of people: the ones that don't answer, and the ones that don't have a home address to send a census form to.  As such, the US Census bureau also makes use of statistical modeling of urban areas.  In the poorer areas of a city, the Census Bureau actually sends people around to count up how many people there are.  Sure, they may get some people twice, but they're probably missing just as many, if not more people.  They then use statistical modeling to project what the population of that city is.  Census takers also go door to door to make sure people have filled out their census forms.  The Census Burueau tries to get as much accurate information as possible, as such, its forbidden by law to share some of the information that it recieves that might get people arrested.  This way, they can count things like illegal immigrants and people who don't pay taxes.

There are 193 countries in the world today. \n\nUnless you don't count Taiwan.\n\nTaiwan is not considered an official country by many, which would bring the count down to 192 countries. Although Taiwan operates as an independent country, many countries (including the U.S.) do not officially recognize it as one. Because the People's Republic of China considers Taiwan a breakaway province of China, countries who wish to maintain diplomatic relations with China have had to sever their formal relations with Taiwan (more than 100 countries, however, have unofficial relations with Taiwan).

Hey!  Let's all copy and paste!\n\nVatican City - 0.2 square miles - The world's smallest state, the Vatican has a population of 770, none of whom are permanent residents. The tiny country which surrounds St. Peter's Basilica is the spiritual center for the world's Roman Catholics (over 1 billion strong). Also known as the Holy See, Vatican City is surrounded by Rome, Italy.\n\nState of Vatican City with an area of 108.7 acres however this is not a soverign nation. and there are no citizens. residents are only transient. if for sovereign nation with actual citizens is the basis, Monaco is the smallest with an area of 1.95 sq kms\n\nState of Vatican City with an area of 108.7 acres however this is not a soverign nation. and there are no citizens. residents are only transient. if for sovereign nation with actual citizens is the basis, Monaco is the smallest with an area of 1.95 sq kms\n\nIt depends on whether you want to count Vatican City or not. While the Vatican is treated as it's own country, some scholars don't count it as a sovereign nation. Vatican City measures 0.44 square km, so if you count this capital of the Roman Catholic Church, it's the smallest country.\n\nFor those who argue that Vatican City doesn't count, the world's smallest country is Monaco (1.95 square km).

Define "country".\n\nBy most accounts the answer is 193 - 192 members of the UN, plus  the Vatican.\n\nThen there's stuff like Taiwan, which is de facto independent but doesn't have much of international recognition. There are places like Palestine, which are recognized by some countries but not by all. There are places like South Ossetia, which is pressing for independence from Georgia, which voted for independence, but which isn't having international recognition. There are places like the Western Sahara, which doesn't have a government so much as a war. There are places like Tibet, which by right ought to be independent but was pwnzored by China and hasn't done that much to regain independence. There are places like Sealand, which is a small pier off the coast of Britain that claims independence and runs an essentially law-free and therefore lawsuit-free Internet hosting service.\n\nAnd so forth. If you count the number of named entities which consider themselves independent, it's well over 200. But that's not what most people consider a "country".

By Most Accounts, 193 is the Correct Answer\n\nA very frequent geographical question is "How many countries are in the world?." Different numbers pop up when one inquires or reads about the number of countries in the world. Each source you use often yields a different answer.\nUnited Nations\n\nThere are 191 members of the United Nations. Unfortunately, the number 191 is too often used to represent the number of countries in the world. Although this number represents almost all of the countries in the world, there is still one country (the Vatican City) that is independent and has chosen not to become a member of the U.N.\n\nU.S. Department of State\n\nThe United States' State Department recognizes 192 independent countries around the world. \n\nTheir list of 192 countries reflects the political agenda of the United States of America and its allies. Missing from the State Department's list is one entity that may or may not be considered a country, depending on who you talk to.\nThe One Outsider\n\nTaiwan meets most of the requirements of independent country or state status. However, due to political reasons, it fails to be recognized by the United States and much of the rest of the world.\n\nTaiwan was actually a member of the United Nations (and even the Security Council) until 1971, when mainland China replaced Taiwan in the organization. Taiwan continues to press for full recognition by other countries, to become "part of the club" and fully recognized worldwide but China claims that Taiwan is simply a province of China.\n\nThus...\n\nYour Guide considers there to be 193 countries, which is probably the best current answer to the question, "How many countries are in the world?" unless Taiwan is officially absorbed into China at some point, in which case the answer would be 192.\n\nHowever...\n\nRecognize that there are dozens of territories and colonies that are sometimes erroneously called "countries" but don't count at all - they're governed by other countries. Places commonly confused as being countries include Puerto Rico, Bermuda, Greenland, Western Sahara, and even the components of the United Kingdom (such as Northern Ireland, Scotland, Wales, and England - sorry folks, they're not countries, states, or nation-states).

I would enter in my browser the name of the country that you are looking for and add "demographics" to it. For example: "Peru Demographics"; this should guide you to an accessible menu that will offer population, country area/size, topography, work, exports and/or imports, type of government and structure, and areas of special interest such as tourist sites and antiquities.  Hope that this helps you. Jose
