Among racial and ethnic groups, blacks and whites came out winners, but Hispanics slipped down the ladder. Although blacks advanced in income status, they are still more likely to be lower income and less likely to be upper income than whites or adults overall. For Hispanics, the overall loss in income status reflects the rising share of lower-earning immigrants in the adult population, from 29% in 1970 to 49% in 2015. Considered separately, both U.S.-born and foreign-born Hispanics edged up the economic tiers.
