estimate that there are about 5,000-6,000 different languages spoken in the world today.  The imprecision in this estimate is largely due to the fact that some dialects are in the process of diverging and it is not clear that they have reached the stage of being separate languages.  If two people find each other's speech unintelligible, they are usually thought to be speaking different languages rather than dialects.

There are about 200 languages that have a million or more native speakers.   Mandarin Chinese is the most common, being spoken by around 874,000,000 people as a native language.  English is a distant third with approximately 341,000,000 native speakers.

English is far more world wide in its distribution than all other spoken languages.  It is an official language in 52 countries as well as many small colonies and territories.  In addition, 1/4 to 1/3 of the people in the world understand and speak English to some degree.  It has become the most useful language to learn for international travel and is now the de facto language of diplomacy.  In 2001, the 189 member countries in the United Nations were asked what language they wish to use for communication with embassies from other countries.  More than 120 chose English, 40 selected French, and 20 wanted to use Spanish.  Those who wanted English to be the common language included all of the former Soviet republics, Viet Nam, and most of the Arab world.  English is also the dominant language in electronic communication.  About 75% of the world's mail, telexes, and cables are in English.  Approximately 60% of the world's radio programs are in English.  About 90% of all Internet traffic is as well.  However, the percentage of Internet users who are not native English speakers is increasing rapidly, especially in Asia.

In reality, the distribution of languages globally is very complex and difficult to easily describe.  Numerous migrations of people over the last several centuries have resulted in most large nations now having many different languages.  There are at least 165 languages spoken in the United States today.  Consequently, it is somewhat misleading to describe the U.S. as being an English speaking country.  The same caution applies to other multicultural nations as well.

Some parts of the world have unusually high concentrations of different languages.  There are around 900 native languages spoken by the 5-10 million people of New Guinea and its neighboring islands.  That is roughly 1/6 of all languages being spoken by far less than 1% of the world's people.  Other language high density areas have been native California and the Caucasus Mountains north of Turkey and Iran.

The majority of the languages in the world are unwritten and many of them are disappearing.  About 1/2 of the world's languages are no longer spoken by children.  This is the first step in the extinction of a language.  About 2,000 languages now have less than 1,000 speakers.  The most threatened are the indigenous languages of Australia and the Americas.  By the end of the 20th century, about 200 Australian languages survived, but more than 1/2 had less than 10 speakers.  Two dozen had a single elderly speaker.  Young Aborigines now predominantly speak English, especially in urban areas.  There has been a similar pattern in California where Indian languages disappeared at the rate of nearly one a year during the late 20th century.

There are no "primitive" languages.  All languages have a system of sounds, words, and sentences that can adequately communicate the content of culture.  The languages of the so-called "primitive" peoples are often very complex in their grammatical structures.  There seems to be no correlation between a language's grammatical complexity and the technological level of a society or other aspects of culture.  However, cultures that have more complex, diverse economies and advanced technologies have larger vocabularies.  For instance, English has roughly 615,000 non-technical words.  If slang and specialized technical words are added, English has more than 2,000,000 words and is growing at a rate of hundreds to thousands every year.  By comparison, German has about 185,000 non-technical words, French may have less than 100,000, and Spanish even fewer.  The major reason that English has so many more non-technical words is the fact that as it evolved from its Germanic roots, it acquired words from more than 240 other languages.  However, it is unlikely that any one individual knows the meaning of all English words.  Most Americans only use 800-1,000 words in everyday conversation.  A typical American college student knows 20,000-30,000 words by the time he or she graduates.  While this is 20-37 times more than the average person who has not gone to college, it is still less than 2% of all English words.

Every language can create new words to describe new situations and objects.  Therefore, it is not surprising that all languages change through time.  None is static.  However, they change at different rates at different times in response to new social, cultural, and environmental situations.  Some nations strongly resist the acquisition of new words from other languages.  This has been the case with the French government's response to the relentless invasion of English words in recent decades, especially in pop culture and technology.  However, young people in most developed nations eagerly embrace new words regardless of attempts by their governments to retain "language purity."
