The actual assertion that the Census Bureau could behave in such a way as to tilt things one way or the other way in the partisan sense, is, on the face of it, a silly charge. It's the same Census Bureau that's considered to be incompetent by some people, and then some of the same people are saying that this incompetent agency is so clever and so Machiavellian that it can design a census for partisan reasons.
I don't think the government is out to get me or help someone else get me but it wouldn't surprise me if they were out to sell me something or help someone else sell me something. I mean, why else would the Census Bureau want to know my telephone number?
If we look at American history, between 1942 and 1947, the data that was collected by the Census Bureau was handed over to the FBI and other organizations at the request of President Roosevelt, and that's how the Japanese were rounded up and put into the internment camps.
The U.S. Census Bureau reports that American homes are 650 square feet larger today than they were in 1980. Unfortunately, so are most Americans.
