I am looking for some statistical and demographic data on US Financial
Services Securities Broker-Dealers.  The information I am looking for
should reflect the Broker Dealer Company Name, # of employees,
revenues per year, location, and any other segmentation information.

This would be for every US broker-dealer.

Does anyone know where I could find this information or does anyone
have it available?

Thanks

You can obtain basic company information about all SEC registered
broker dealers at: http://www.sec.gov/foia/docs/bdfoia.htm

The report contains "the Central Index Key (CIK) numbers, company
names, SEC reporting file numbers, addresses (business addresses are
provided when mailing addresses are not available), and taxpayer
identification numbers of active broker-dealers who are registered
with the SEC."
