Most people think that dialects in the United States are dying out because of increasing mobility and the influence of a relatively homogenous media voice. But this is not the case.
Though there is some erosion of once-isolated dialects, some major dialect areas are actually diverging from each other. For example, a recent survey of the dialects in the United States reveals that the dialects of northern cities such as Chicago, Detroit, Cleveland and Buffalo are actually more distinct today than they were 50 years ago.
Studies of socio-ethnic language varieties such as African-American English and Hispanic English show that they are also more robust and distinct than they were in the past. Finally, new regional dialects are emerging in California, Oregon and Washington, as West Coast dialects develop a distinct regional voice that conveys, in part, a newly emerged social and regional identity.
