An Indiana data detective has been been browsing the web to see what news and information is out there about the American Community Survey, noting that "Google yields about 2 million items when searching for American Community Survey and the top links are to the Census Bureau. However, on the first results page there are a number of blogs referenced that purport to be reactions from recipients of the survey..."
Here is just one of the many links found.
It appears that there is a great deal of concern about the "intrusiveness" of the ACS and about privacy, "difficult to assuage in the face of modern technology and general mistrust of 'the government'."
I believe that the Census Bureau, which has little money to publicize the ACS program at all, nevertheless needs to find a way to address these issues. I remember a conversation I had four or five years ago with a data detective. I posited the theory that the USA “PATRIOT” Act and other activities would undermine Census' capacity to gather information in the future. That understandably suspicious future is now.
The data gathered in the ACS, and before that in the long form of the Census, is vitally important to government and industry. Of course, the "short form" questions are required for reapportionment of Congress and state legistures, as well as a myriad of other uses.
