Data reveals United States of Android

The number of smartphone-wielding Americans jumped 8% from Q1 2011 to 78.5 million in Q2, according to comScore's latest figures.

Android grabbed 40% of the market, up 2%, among the 30,000 respondents to comScore's survey in June. In second place is Apple's iOS with 26.6%.

A new infographic from targeted mobile ad company Jumptap, based on data from its 83 million network of users, illustrates the geographic spread of smartphone users in the US.

It shows that consumers in the South and Southwest tend to be Android-biased compared to the rest of the country, while those in the Midwest and Northeast lean towards iOS. California, Texas and Florida over-index for Android use and states in New England and the Midwest over-index for iOS use.

While Android dominates the smartphone platform market, Jumptap's ad click-through rates revealed that Apple's iOS outperforms its rivals.
