The Insurance Information Institute has a great dissection of employment data in the insurance industry written by Dr. Robert Hartwig.  From the article:

In December, except for health insurance carriers, more people were working in insurance than in November. P/C carrier employment rose to 462,300—up 700 from November but otherwise the lowest P/C carrier employment level in over 20 years. Employment in the U.S. reinsurance industry also rose (by 800) and has now recovered the jobs lost since the end of 2008. On the life insurance carrier side, employment rose by 400 jobs (up 0.4 percent) to 375,100. Health insurers shed another 1,000 jobs in December (to an employment level of 423,200) and are down 17,000 for the 12 months ending in December 2010. The number of agents and brokers rose by 1,000, up 0.3 percent in December over November, to 641,700—up 8,600 vs. September 2010. Employment in claims adjusting rose by 1,200, so the December total is now higher than all the monthly reports in 2010.
