Social class factors
Nevertheless, not even all European American New Yorkers use this variety. Upper-middle class European American New Yorkers and suburban residents from educated backgrounds often speak with less conspicuous accents; in particular, many, though hardly all, use rhotic pronunciations instead of the less prestigious non-rhotic pronunciations while maintaining some less stigmatized features such as the low back chain shift and the short a split (see below).
Similarly, the children of professional white migrants from other parts of the US frequently do not have many New York dialect features, and as these two populations come to dominate the southern half of Manhattan and neighboring parts of Brooklyn, the dialect is retreating from their neighborhoods. Many teens attending expensive private prep schools are barely linguistically recognizable as New Yorkers. Nevertheless, many New Yorkers, particularly those of Southern and Eastern European descent from the middle- and working-class, retain varying degrees of what has been coined New Yorkese or Brooklynese within their daily speech.
Beyond New York
Many Jewish-Americans, both Ashkenazic and Sephardic, throughout the United States have some features of a New York accent. This is the case even among some Jewish-Americans who have never lived in New York or New Jersey. This phenomenon is somewhat parallel to the spread of African American Vernacular English to the rest of the United States from its original location in the American South. Because so many Jewish-Americans have a New York-sounding accent, some people may mistakenly believe that a New York accent is a "Jewish accent," when actually, non-Jewish White New Yorkers generally speak with the same accent. Similarly, many Mafia films, most of them set in the 1940s, show many characters speaking English with a New York accent.
