As an early guide to the clusters prepared in the 1980s explains, those who lived in “Young Influential” neighborhoods were the “young, upwardly mobile singles and dual career couples”; mostly they were to be “found in the inner-ring suburb of major cities.” As to priorities: they “don’t care about good schools, because they don’t have children.” Rather, “they want a mall with a sushi bar, gourmet cookie shop, travel agency and a psychotherapy center.” They read books at twice the rate of the national average, and they tended to vote Republican. By contrast, Claritas found that those living in the “Bohemian Mix” areas, like New York’s Greenwich Village, were “an eclectic melange of never-married and divorced singles, young Turks and older professionals, blacks and whites” who held “benefit dances for the Sandinistas.” “Squash, racquetball and jogging” were among their typical pastimes.
