In its April report, Google owned AdMob’s statistics revealed that, even though Android devices are definitely selling strongly, the combined efforts of the iPhone and iPod Touches still outnumber Android users 2 to 1.
According to the results, the iPhone and iPod Touch have a combined total userbase of 18.3 million, which compares to Android’ 8.7 million. These numbers only reflect the userbases in America however. Internationally however, the ratio is even more in Apple’s favor with iPhone and iPod Touch devices outnumbering Android 3.5 to 1. This definitely supports the notion that 75% of Android devices are used in North America, compared to just 49% when it comes to iPhones.
However, these numbers still can be skewed one way or another simply because the number that is simply shipped can be different when compared to actual sales and how many of the devices are no longer used.
