In an influential study of ethnic identity in the United States, Glazer and Moynihan (1963) stated that the most important point to be made about the "American melting-pot" is that it never occurred. They argue that rather than eradicating ethnic differences, modern American society has actually created a new awareness in people, a concern about roots and origins. Moreover, many Americans continue to use their ethnic networks actively when looking for jobs or a spouse. Many prefer to live in neighbourhoods dominated by people with the same origins as themselves, and they continue to regard themselves as "Italians", "Poles" etc., in addition to being Americans - two generations or more after their ancestors left the country of origin.
