Twelve percent of African American and 14 percent of Englishspeaking Hispanics make and receive more than 30 calls a day on their mobile phones.

Four percent of whites report placing and receiving that many calls. African American and Hispanic texters typical send and receive 10 texts a day whites who text typically send and receive 5 texts a day.Texting among adults has reached the mainstream and the charge is being lead by AfricanAmericans, Hispanics and young adults, said Amanda Lenhart, Senior Research Specialist at the Pew Research Centers Internet American Life Project and author the report. Of course, none of these adult groups hold a candle to teens when it comes to texting, who swamp adults in messages sent per day by a factor of 5.
