I've recently learned of two very interesting interactive maps. One locates computer animation studios and the other gaming studios. There may be an overlap between them.
There are obvious benefits to these sites for anyone trying to find a job. However, not everyone realizes the repercussions of various locations until they've experienced them.
I'm not talking about specific cities, but I am talking about studio density. Depending on where someone is in his or her career, density makes a big difference.
The problem with low density locations (i.e. with just one or two studios) is that if you get laid off or a studio closes, you have to relocate in order to continue working in the industry. This is what happened to people in Arizona when Fox closed it's studio, to people in Florida when Disney closed there, and to people in Portland when Laika laid off the crew after Coraline.
This isn't much of a problem for people who are unattached, but it becomes a much larger problem once people form romantic relationships and have children. Uprooting other people in pursuit of one's own career can create powerful resentments.
As a result, people tend to flock to those areas with half a dozen or more studios, so that if they have to change jobs, they don't have to relocate. Of course, it means that people starting their careers often have an easier time finding work in the smaller centers as it is harder to entice people to move there.
Regardless of where you might be in your career, these maps may prove useful.
