I am looking for specific statisitics on European-American marriages
and relationships.  For example:
How many Euro-American long term relationships and/or marriages are
there in the U.S. today?
What percentage of marriages in the U.S. are of an American to a
European?
How many U.S. born people are currently in long term relationships
and/or marriages to Europeans?
What percentage of marriages in the EU or Europe are Europeans who are
marrying Americans?
Answers to one or more of these questions will suffice, given that the
information source is cited and that the answer and source are
credible. (i.e. Please do not get the information off of Joe-Bob's
homemade website).  Further information on European-American
relationships is helpful, but I need to have specific and reliable
statistics of some sort.  Finally, if you can find information about
German-American relationships (the statisitical information that I
have already requested related to European-American relationships)
that would suffice, as well, for an answer to my question.  Thank you.

Hello, Since you indicated that information about the German-American
aspect would suffice,I am answering the part of your question that
referred to Germany. I did what I consider an exhaustive search and
could actually find ONLY German-American information!

According to the German Embassy in Washington, D.C., website:

          http://www.germany-info.org/relaunch/info/facts/society.html

There are, as of May 2000, 1,3 million bi-national married couples in
Germany.
Of these, 4.1 % are couples where both spouses are foreign nationals.
         
         51.0 % have foreign national wives. Of these foreign national
wives, 75% are European (12 % Polish, 8% from the former Soviet Union,
7% Turkish), 13% Asian, 8% American,3% African, 1% other.
   
         49.0% have foreign national husbands. Of these foreign
national husbands, 79% are European(15% Turkish, 14% Italian, 7%
Austrian, 7% African, 6% American, 6% Asian, 2% other.)

There are 17.37 million all-German couples (89.3% of married couples
in Germany)
There are 1.3 bi-national married couples (6.6% of married couples in
Germany)

There you have it!

On target.

If you speak German this might be of interest to you:

http://www.destatis.de/presse/deutsch/pm2001/p3340023.htm

It's an official German statistic on German marriages with
a foreign partner. 
It will allow you to answer the question from the viewpoint of
"who is living in Germany"

Hope this is helpful.
