Expect more than one mobile phone for every US man, woman and child by 2013, according to SNL Kagan data released in August 2007.



That is up from the current 84% penetration level of the US population (including business, consumer and double users) who have mobile phones. Kagan estimates that mobile phone subscribership will grow about 3% annually through 2017, faster than the country's 1% population growth.

"If carriers can hold onto their position in the revenue chain, data is poised to give them a second growth spurt," said Sharon Armbrust, a senior analyst at SNL Kagan, in a statement.

"While subscriber units and voice revenue will inch along, we expect data revenue to grow at a compound annual 14% rate over the next 10 years, rising to at least 22% of service revenue, compared to under 10% today," she said.

SNL Kagan estimates total mobile industry average revenue per user to grow at an inflation-paced compound annual growth rate of 1.5% over the next 10 years, to $61.09 in 2017 from $52.38 in August 2007.

Average revenue per user to date was up 45% to $8.58 in the first quarter of 2007 versus $5.92 in the year-ago period.
