REVENUE GENERATED BY SOLE PROPRIETORSHIPS AND PARTNERSHIPS AROUND
THE WORLD.  

In the US, sole props are the most common organizational
form.  But they are very small, and account for about 13% of sales in
the US - corps are about 80%.  Partnerships are about 7%.  What about
outside of the US?

[for this question, can we get worldwide data?  If not, for a range of
countries - like, say, industrialized vs non?  Or, if not, for a few
countries?]

Each country likely defines sole proprietership and partnerships
somewhat differently, making comparisons difficult. Also accounting
standards vary at least a little making revenue difficult to compare.
