More than half of all Americans play video games, a recent study by the Entertainment Software Association has found.

Smart phone gaming is factored into this, with the study recognising that usage has increased by 22% since 2012, but just over half of all US households also own an average of two consoles, evidencing that "casual" gamers aren't the only ones playing. In fact, 68% of games were found to be played on console in gaming households compared to 53% on smartphones.

The average gaming household has at least one dedicated game console, pc, or smartphone.

The study also found that:

- Wireless device use increased by 37 percent, over 2012.

- The average American gamer is 31-years-old.

- Women age 18 or older represent a significantly greater portion of the game-playing population (36 percent) than boys age 18 or younger (17 percent).

- The number of female gamers age 50 and older increased by 32 percent from 2012 to 2013.

- The average number of years gamers have been playing video games: 14.

- Adult gamers have been playing for an average of 16 years, with adult men averaging 18 years and adult women averaging 13 years.

- The average age of the most frequent game purchaser is 35.
