Audience

I looked at stereotypical audiences for the post-apocalyptic genre we studied. Using YouGov, I found and combined the audiences for the film openings we studied to show a general audience for the post-apocalyptic genre.

All the movies have an older, male age range except 28 days later which is slightly younger. All have a social grade of ABC1 which means well educated, well-paid jobs and intelligent. The interests are all educated and suggest the older generation. The Road suggests an older audience however due to the 16-20 hours a week online. Compared to 28 days later with 41-45 hours it suggests The Road could contain features more suitable for an older audience. Interestingly, all the average audiences' entertainment preferences have action, adventure and some sci-fi elements. What's strange is that almost all contained some form of comedy which is the opposite of most general post apocalyptic movies.
From this we can gather the general post-apocalyptic audience, according to YouGov, is:
