The United States does not have an official language. However, 81% of the population speaks English as a native language. The variety of English spoken in the U.S. is known as American English. The second most popular language is Spanish.
Since the U.S. is a nation of immigrants, the American culture originated by mixing cultures from across the world. Due to the influence of television, people from other countries may already have an idea of what American culture is like even though they have not been there. Stereotypes are not always true, but there may be some level of reality in a few of them.
For example, American’s tend to be friendly and informal. People will not wait to be introduced before talking to one another. In fact, an American standing in a queue, will often start speaking to a stranger next to them to pass the time. Another stereotype that holds some truth is that “time is money.” Americans can sometimes assign value to how people “save” and “spend” time.
