One factor fueling General American's popularity was the major demographic change of twentieth-century American society: increased suburbanization, leading to less mingling of different social classes and less density and diversity of linguistic interactions. As a result, wealthier and higher-educated Americans' communications became more restricted to their own demographic. This, alongside their new marketplace that transcended regional boundaries (arising from the century's faster transportation methods), reinforced a widespread belief that highly educated Americans should not possess a regional accent. A General American sound, then, originated from both suburbanization and suppression of regional accent by highly educated Americans in formal settings. A second factor was a rise in immigration to the Great Lakes area (one native region of supposed "General American" speech) following the region's rapid industrialization period after the American Civil War, when this region's speakers went on to form a successful and highly mobile business elite, who traveled around the country in the mid-twentieth century, spreading the high status of their accents. A third factor is that various sociological (often race- and class-based) forces repelled socially-conscious Americans away from accents negatively associated with certain minority groups, such as African Americans and poor white communities in the South and with Southern and Eastern European immigrant groups (for example, Jewish communities) in the coastal Northeast. Instead, socially-conscious Americans settled upon accents more prestigiously associated with White Anglo-Saxon Protestant communities in the remainder of the country: namely, the West, the Midwest, and the non-coastal Northeast.
