For fascinating, provocative reading about where the Census Bureau will reside in the federal government organization, read the Feb 10, 2009 Wall Street Journal: "Why Obama Wants Control of the Census: Counting Citizens is a Powerful Political Tool" (author: John Fund). http://online.wsj.com/article/SB123423384887066377.html.
Serious changes may be happening, and more quickly than imagined. Even the seven former Census directors who support turning the Census into an independent agency recommended doing so after the 2010 Census.
To quote the article, "[S]tatisticians at the Commerce Department didn't think [Obama's changes] would mean having the director of next year's Census report directly to the White House rather than to the Commerce secretary."
Lots of food for thought.
