While searching for information on audio engineering, google highlighted this:

Although there are abundant audio engineer jobs in America, a large number of them are in the Northeast. Oregon is the best state in the country for audio engineer jobs, and Maine has the second-highest median salary in the country. Oregon is the best state for jobs for audio engineers, and Rhode Island is the worst.

I'm astonished there are that many audio engineering jobs. Jobs to me means people are actually earning a living and Oregon happens to be the best place in the USA.  I wonder why?
