Among those who use cell phones to talk, women were heavier users than men, the survey found. Women use 22 percent more minutes of talk time per month on average than men — 856 minutes a month compared to men's 667. American women also text more, sending or receiving an average of 601 SMS messages a month compared to the 447 monthly text messages sent or received by the average American male.
Blacks use the most voice minutes — on average more than 1,300 a month, Nielsen found. Hispanics are the next most talkative group, chatting an average of 826 minutes a month. Even Asians/Pacific Islanders, with 692 average monthly minutes, talk more than whites, who use roughly 647 voice minutes a month.
The voice and text results were compiled from one year (April 2009-March 2010) of mobile usage data gathered by the The Nielsen Co., which analyzes the cell phone bills of more than 60,000 U.S. mobile subscribers each month.
Morgan said cell phone usage for voice, text and data is growing rapidly in Oklahoma and across the nation.
"The demand is incredible," he said. "It doesn't matter where you are, people are wanting it."
