AdMob: 57% of 44 million iOS devices are from outside the US

By Slash Lane

Apple was the top device manufacturer on the AdMob network in May, according to the ad agency's latest data, with 44 million unique iOS devices tracked, and 57 percent of those from outside of the U.S.

The results from the May 2010 Mobile Metrics Report show that the iOS platform experienced its strongest growth in unique devices in the past year in Asia, Oceania and Western Europe. As a result, less than half of all unique iOS devices -- 48 percent -- are from North America. Another 28 percent hailed from Western Europe, while 15 percent came from Asia.

Among countries, 43 percent of all iOS devices came from the U.S., followed in a distant second by the U.K. with 9 percent. France ranked third with 6 percent, followed by Canada (5 percent) and Japan (4 percent).

The May 2010 survey also found that 58 percent of iPad users were in the U.S. during the month. In second was Japan, with a 5 percent share, while China and the U.K. both carried 4 percent.

Worldwide, AdMob tracked 29.3 million unique iPhones, representing most of the iOS devices seen. When the iPad and iPod touch are included, the network found 43.8 million unique iOS devices. That compares with just 12.7 million Android handsets.

In the U.S., the ratio of iOS devices to Android devices was about 2-to-1, but globally, Apple has a much greater lead, enjoying a 3.5-to-1 ratio in its advantage.
