smartphone phone users in ethnic minorities

As of December 2010, nearly a third (31%) of all mobile consumers in the United States owned smartphones, cellphones with app-based, web-enabled operating systems. But smartphone penetration is even higher among mobile users who are part of ethnic and racial minorities in the U.S. – namely Asian/Pacific Islanders (45%), Hispanics (45%) and African-Americans (33%), populations that also tend to skew younger. Meanwhile, only 27 percent of White mobile users reported owning a smartphone.
