The percentage of Americans who say they are in the lower-middle or lower class has risen from a quarter of the adult population to about a third in the past four years, according to a national survey of 2,508 adults by the Pew Research Center.
Not only has the lower class grown, but its demographic profile also has shifted. People younger than 30 are disproportionately swelling the ranks of the self-defined lower classes. The shares of Hispanics and whites who place themselves in the lower class also are growing.
Among blacks, the story is different. The share of blacks in the lower class has not changed in four years, one of the few demographic groups in which the proportion in the lower classes did not grow. As a consequence, a virtually identical share of blacks (33%) and whites (31%) now say they are in the lower class.
