There are over 1000 native languages described, and the number is further increasing day by day as the understanding is increasing about how each language is spoken differently.
One might suppose, that linguists would have a clear and reasonably precise notion of how many languages there are in the nation, but this is not so, The reason for this lack is not (just) that parts of the world such as highland New Guinea or the forests of the Amazon have not been explored in enough detail to ascertain the range of people who live there. Rather, the problem is that the very notion of enumerating languages is a lot more complicated than it might seem.
Another problem was that these languages are not uniformly distributed, just as some areas of world have high diversity of plants and animals, and other don't, similar is the case when it comes to studying languages
Another emerging issue is that the number of people speaking a particular language is declining day by day making it further difficult to study them,
Whatever the be the linguist diversity at the present, it is steadily declining, as local forms of speech increasingly become moribund before the advance of the major languages of world civilization. When a language ceases to be learned by young children, its days are clearly numbered, and we can predict with near certainty that it will not survive the death of the current native speakers.
The situation in North America is typical. Of about 165 indigenous languages, only eight are spoken by as many as 10,000 people. About 75 are spoken only by a handful of older people, and can be assumed to be on their way to extinction. While we might think this is an unusual fact about North America, due to the overwhelming pressure of European settlement over the past 500 years, it is actually close to the norm.
