What percentage of people employeed in the United States work for 1)
for profit organizations 2) not for profit organizations and 3)
government.  The total should equal 100% of everyone employeed in the
US.  In other words, what's the percentage of people that work for for
profit organizations, what percentage of people work for not for profit
organizations and what percentage of people work for the government? 
Please provide the source(s) which should also include the date of the
data.  Also include the number (not just percentage) of people
employeed in each of those 3 areas.  Thanks.

I have found precisely the information that you need in a report
prepared by a group called "Independent Sector," a Washington
organization that represents charities and charitable foundations.

This report reflects figures from 2001, the latest data available from
the U.S. Bureau of Labor Statistics. A more detailed breakdown of
these figures, and some useful charts, may be found elsewhere in the
report, linked below.

(When computing these percentages from the data, I have rounded to the
nearest percentage.)

Total number of US workers: 
131,800,000

For profit organizations: 
98,400,000 workers (75% of the total workforce)

Not for profit organizations: 
12,500,000 workers ( 9% of the total workforce)

Government: 
20,900,000 workers (16% of the total workforce)

Here you'll find another article based upon the same statistics:

I hope this is helpful. If anything is unclear, please request
clarification; I'll gladly offer further assistance before you rate my
answer.
