The Constitution (Article 1 Section 2) specifically gives the House of Representatives power to decide the questions present in the census: "[I]n such Manner as [the House] shall by Law direct."
Here are the questions asked in the first census, conducted in 1790:
* Name of the head of each household.
* How many free white males age 16 and older.
* How many free white males under age 16.
* How many free white females.
* How many of all other free persons.
* How many slaves.
I don't suppose you're a fan of Michelle Bachmann's, are you? Here's a recent response a FOX News(!) anchor gave Bachmann regarding this:
“We’ve had a lot of good years since then,” Kelly said. “That was a different time and a different era. We’ve had decades since then when, at least to our knowledge, this information hasn’t been abused. So how do you respond to people who say, ‘Look, we’ve been doing it for decades since then. The law is what it is and you as a lawmaker should know better than to break it.’”
