I'm intrigued by the nature of this survey? Do you really think you'll find a commonality among people's beliefs based on what job they do?! Sure, it's easy to assume someone that collects funds for the local church is religious and the lawyer probably isn't, but in my profession - media, since you ask - I know people who do exactly the same job and yet have wildly differing faiths or, in my case, a deep suspicion of all organised religions. I fail to see your point
