So there are lots of articles about hot jobs - healthcare usually comes as well as some odd ones such as education (we have to keep educating kids - although States are cutting their budgets left, right and center). 
So I did my own survey on monster.com.

I searched for jobs in Los Angeles  - 40 pages came up (5000 plus jobs)  Then I broke them down.  These are some of the results.

Accounting and Auditing - 337 jobs (supposed to be a growth area - the theory is that someone needs to police industry)
Advertising and PR          - 251 jobs (we do have Boeing and Northropp Grumman)
Aerospace                         - 333 jobs
Automotive                        -  77   jobs  (yikes - it is a mess - both for sales and mechanics etc.)
Banking                             - 269 jobs   (maybe the bailout did help)
Biotech/Pharmaceutical - 220 jobs   (supposed be a growth area doesn't seem that way)
Broadcasting etc.             -142 jobs    (is very popular area and jobs often are not advertised and it's been hit by the economy)
Retail                                  - 347 jobs    (retail is down - 300 jobs sounds a lot but given the natural turnover in the industry that is low)

So what does this tell you?  That stats are just stats.  That even in areas where there are not supposed to be jobs there are jobs.  And that beware of jumping into a "growth" area only to find it's no better than the job you left.  In the end it's down to you.  You can make it happen!
