New research released by The Nielson Company on Monday shows the application usage of Android users with the most popular app across all groups being the Android Market, obviously. 

The study focused on data from thousands of Android smartphones in Nielson's Smartphone Analytics research group. The data in the graph shows the percentage of people who used each application in the last thirty-days, separated into three age groups. In each age group Facebook comes behind the Android Market followed by a range of Google's own apps. Google Search, Maps, Gmail and YouTube were all in the top six in each age group. 

Games such as Angry Birds and Words with Friends also made each grouping but in different rankings. Angry Birds usage tended to rise with age as Words with Friends lost users by aging. Google's own Google+, the new social network released by Google earlier this year, did not make any of the lists as Facebook still dominates the social networking world. Somewhat surprisingly is Amazon's Appstore which now appears to be gaining more and more ground as it appears in each age group. The Amazon Appstore also has more older users than younger. 

Android isn't just for those ages 18-44 as Nielson says that research is currently being done for those older users. They say that more data on older smartphone users will be released "early next year."
