I want to know the demographics of people originally from India in
South East Wisconsin, Racine,Kenosha area and appleton, fond du
lac(fox valley) area in Wisconsin for starting a business

Don't know much about demographics in the US, but I know that there
are Indian associations in Madison, Wisconsin, and in Chicago, which
is not far from Madison (under three hours), there is a newspaper for
the Indian community; and they might have such information at their
fingertips.

For example, there is the Indian Graduate Students Association at the
University of Wisconsin-Madison,
http://www.sit.wisc.edu/~india/about_igsa/about_igsa.shtm. 

There is also an Indian restaurant in Wisconsin Dells called Ananda's,
http://www.geocities.com/anandasfood/restaurant; the owner is from
India, and has many Indian customers. It happens to be the only Indian
restaurant for fifty miles in that part of south central Wisconsin;
there are not many Indians locally.

Here's a comprehensive set of links to all things Indian in the state:

Best wishes with your business.

I realize that your question is expired, but I want to let you know
that you can find out almost anything from the U.S. Census, at
http://factfinder.census.gov .  I did a quick search and found that in
2000 there were 167 people in Kenosha County who were born in India
(out of 149,577
), and 162 people in Racine County who were born in India (out of
188,831).

You can also find national origin statistics (for example, those who
were born in the U.S. but are of Indian descent).  You can find pretty
much anything, for any geographic area.
