the upper middle class consists of well-educated professionals with graduate degrees and comfortable incomes.Sociologists Dennis Gilbert, Willam Thompson and Joseph Hickey estimate the upper middle class to constitute roughly 15% of the population. Using the 15% figure one may conclude that the American upper middle class consists, strictly in an income sense, of professionals with personal incomes in excess of $62,500, who commonly reside in households with six figure incomes.[1][7][16
