By 2013, nearly half of the United States' 117.4 million Internet users will own tablets, the study estimates, based on a survey examining demographics and consumer behavior and attitude toward advertising.
The survey found that 31 percent of consumers already own tablets this year--a 12 percent increase from last year.
A look at the breakdown of which platform tablet users own, Android has actually caught up to Apple because of Kindle sales. In 2011, sales were skewed toward Apple, with 72 percent of tablet owners using some form of the iPad and only 32 percent on Android.
This year, about half of owners use an iOS tablet, while the other half use an Android tablet, with a small percentage using both.
The report also notes that the growth of the tablet industry means more opportunity for monetizing content and advertising opportunities, but it's in direct relation to how users are consuming content on their tablets. More on that Wednesday, according to the association's blog post.
Other information from the report:
• Tablet users are 56 percent male and 44 percent female
• 59 percent of tablet users are from households earning an income of US$50,000 or more
• The study was based on a survey of 2,540 Internet users between the ages of 8 and 64
