US specific film data for 2012
In 2012, the ethnic composition of frequent moviegoers looks much the same as in 2011, with Hispanics oversampling as frequent moviegoers relative to their proportion of the population. The 2012 increase in frequent moviegoers skews more significantly towards Caucasians and Hispanics than other ethnicities.
The gender composition of moviegoers (people who went to a movie at the cinema at least once in the year) in 2012 skewed slightly more towards women than the overall population (and up 1 percentage point versus 2011), while tickets sold continued to be split evenly among both genders.
Although Caucasians make up the majority of the population and moviegoers (140 million), they represent a smaller share of 2012 ticket sales (56%). Hispanics are more likely than any other ethnic group to go to movies, and purchased more tickets in 2012 compared to 2011.
