I am very interested in finding out all I can regarding the
demographics on Hispanics, most specifically in southern Louisiana,
but also generally all over the U.S.  The latest census info is a good
starting point, but I want to know who has delved much deeper.  I'm
interested in determining the numbers of Hispanics, how well they were
counted by the census, breakdowns in detail - whereever available - re
financial impact - as consumers, business owners, as Republicans, as
Democrats, as unregistered voters, as illegals, migratory habits,
voting trends (e.g., shift to more Republican with gains in
affluence).  Who are they, where are they living, how are they living,
where are they spending their money, where are they working, do they
have HEALTH CARE, what kind of access do they have to SOCIAL SERVICES,
EDUCATION, ETC.  What percentages are completing high-school, what
wages are they earning, what organizations are out there that provide
assistance, support, education (whether they are reaching the
Hispanics or not), who else is studying this, compiling data, how do I
find them.  INTERNET LINKS, STATISTICAL STUDIES/DIAGRAMS/CHARTS (WITH
AUTHOR INFO), ALSO POWERPOINT/COMPUTER PROGRAMS/PRESENTATIONS, SOURCES
OF (MORE RAW) DATA THAT CAN BE ANALYZED, MAGAZINE ARTICLES/CITATIONS,
CONTACT NAMES/INFO ALL MUCH APPRECIATED.
   AND WHO ELSE HAS WORKED ON THIS, OR IS WORKING ON THIS, WITH WHOM I
CAN SHARE INFO AND DATA TO BE FURTHER STUDIED?

   I DO NOT NEED, AND DO NOT WISH TO PAY $30 FOR, A RESPONSE THAT
MERELY
SCRATCHES THE SURFACE AND ONLY POINTS TO THE SAME THING A GENERAL
SEARCH ENGINE SEARCH WOULD GIVE IN RESPONSE TO "HISPANICS DEMOGRAPHICS
AND DATA".  NOR FOR WHAT A $5 GOOGLE ANSWER SEARCH MIGHT GET ME. I
HOPE TO BE LUCKY AND HAVE A REAL PRO RESEARCHER DELIVER REAL RESEARCH
THAT RESPONDS TO MUCH, IF NOT MOST, OF WHAT I ASK FOR.
MANY THANKS!!!!!!!!!!!

"How well they were counted by the census" might be a bit difficult,
short of someone conducting another census, and doing it better.

Your question might get better responses if it was broken into smaller
questions, like:

Hispanics and politics
Hispanics and health care
Hispanics and education
Hispanics and employment
Hispanic migratory habits

Also, are you interested in any reports that you would have to
purchase, or only data that can be found for free on the web?

In response to robertskelton:  Thanks for jumping right on this. 
Perhaps my question should be broken down into several smaller
questions, as you suggested.  But I am interested in many broad and
interconnected strands of info, and I'd like to see what info I can
get with this all-encompassing attempt.  But follow-up, more
subdivided questions may (then) be in order.
   And, yes, if there is some source of really good data recommended
but at an additional price, I would pay for it.  But my budget is
definitely limited.
   GRACIAS!!
