Q. Do you have any sources or statistics on the average ages for female chiropractors, and perhaps how old is the oldest practicing chiropractor?
The following two web pages may have most of the data you are seeking regarding chiropractic employment statistics.
The Bureau of Labor Statistics page on chiropractic professions is located here...
The tabs along the top of the Occupational Outlook Handbook will give you quite a lot of information.
DataUSA's web page contains more graphical representations of the chiropractic work environment, it is located here...
I hope these snapshots of the current chiropractic environment will help.
