That's very kind of you...thanks. Here's a replay of the info I provided earlier:
Uncle Sam doesn't define the retail industry quite the way you do.
According to the latest Census Bureau figures (for 2002), there were
713,986 retail establishments in the US. You can see the breakout of
the main categories here (sorry for the ludicrously long URL):
However, these numbers don't include restaurants, which is a separate
NAICS code all together, and may not include other sectors that are of
interest to you.
Each of the categories at the above link can be broken out into
detailed subcategories. For instance, the "Motor vehicle & parts
dealers" breaks out into:
--New car dealers
--Used car dealers
Other motor vehicle dealers
--Recreational vehicle dealers
Motorcycle, boat, & other motor vehicle dealers
--All other motor vehicle dealers
Automotive parts, accessories, & tire stores
--Automotive parts & accessories stores
By the way, don't be shy about any of this. If you would like any
additional information, you're certainly entitled. Just let me know
by posting a Request for Clarification, and I'll be happy to assist
you as best I can.
