Thanks for your clarification.
I think you'll find most of the information you're looking for at this
Census Bureau site on the size of businesses in the US in 2001:
Starting from the first table:
U.S. - All industries by Employment Size of Enterprise
you can see that there were 5,657,774 firms in the US in 2001 (click
on the word "Firms" -- or on other underlined terms in the table -- to
The vast majority of these are undeniably "small" businesses, no
matter what definition one uses. There were 703,837 firms with no
employees, 2.7 million firms with 1-4 employees, and so on, down the
table. In sharp contrast, there were only 930 firms in the entire
country with 10,000 or more employees -- these pretty much overlap
with the Fortune 1000 type of companies.
On the right hand side of the table, is a column with "Annual payroll"
figures. Here, the trends are reversed. Even though there are
millions of businesses with 1-4 employees, the total payroll they
payout is fairly small -- $34.29 billion dollars.
The 930 largest firms at the bottom of this first table, in contrast,
have a total payroll of $1.248 trillion!
An industry-by-industry breakout is presented in the last table on
this page, in a somewhat different format.
For each listing, the table shows the total number of firms in that
category, followed by the percent of employment accounted for by firms
of different sizes. Similar data is presented for total number of
employees in the sector.
An example will (hopefully) make this clear.
In the "Manufacturing" sector, the table tells us that:
--there are 305,160 manufacturing firms overall
--27.2% of the firms employ 20 or more people
(conversely, 100-27.2 = 62.8% of manufacturing firms employ fewer than
--Only 6.6% of manufacturers employs 100 or more people, and
--only 1.5% employs 500 or more.
Therefore, if you want to consider 500 employees as a cut-off between
smaller and larger firms, you can see that only 1.5% of manufacturing
firms would be classified as "large" while the vast majority are
Shifting over to the next set of columns, you can see that:
--Manufacturers employ a total of 15,950,424 people
--92.1% of workers are employed at firms with 20 or more workers
--75.8% at firms of 100 or more workers
--58.4% work for "large" firms that employ 500 or more people.
Thus, in the manufacturing sector, somehwat more than half the workers
(58.4%) work for "large" firms, while the rest work for smaller
Interestingly, if you look at the top line in this table for "All
industries", you can see that almost exactly half (50.1%) of all
workers are employed for firms of 500 or more people, while the other
half work for SME's.
I threw a lot of numbers at you, and I hope this is all clear.

additional explanations, or any additional information at all. Just
