Based on age, gender and income, how many people in the United States are using cell phones?

Consumers in the U.S. bought 31 million mobile phones in Q1 (2008), spending $2.7 billion, according to data the NPD Group will release tomorrow. The problem: That's a 22% year-over-year decline in unit shipments and a 7% decline in revenue from Q1 2007 -- in an industry that's still supposed to be growing. http://www.alleyinsider.com/2008/5/economy_burns_cellphone_sales_down_22_in_q1 Here are some statistics from 2007: 18 to 29 year olds account for a smaller proportion of this group compared to last year (49%, compared to 55% last year). This does not mean that 18 to 29 year olds are less likely than in 2006 to use a cell phone only. In fact, the incidence of cell phone only usage among 18 to 29 year olds actually increased slightly (32% of 18 to 29 year olds use a cell phone as their only telephone service, compared to 26% last year). It simply means that the cell phone only usage also increased among older individuals, resulting in that group now accounting for a greater proportion of the cell phone only population than it did in 2006; Those with household income of $75,000 or more now account for a greater proportion of cell phone only users compared to 2006 (28%, compared to 22% in 2006); Those who consider themselves Independent (as opposed to Democrat or Republican) account for a greater proportion of cell phone only users compared to 2006 (36%, compared to 29% in 2006). The percentage of Independents also increased among the general population sample from 2006 to 2007 (from 25% to 32%), so this may have more to do with the current political landscape than anything about cell phone only users specifically. http://www.harrisinteractive.com/harris_poll/index.asp?PID=890 Jul 11 08, 11:25 AM
