The Census Bureau tells us that this year, it will use a shorter questionnaire, consisting of only 10 questions. From what I see, only one of them serves the constitutional purpose of enumeration -- namely, "How many people were living or staying at this house, apartment or mobile home on April 1, 2010?" The Census Bureau's shorter questionnaire claim is deceptive at best.
The American Community Survey, long form, that used to be sent to 1 in 6 households during the decennial count, is now being sent to many people every year. Here's a brief sample of its questions, and I want someone to tell me which question serves the constitutional function of apportioning the number of seats in the U.S. House of Representatives: Does this house, apartment, or mobile home have hot and cold running water, a flush toilet, a bathtub or shower, a sink with a faucet, a refrigerator, a stove? Last month, what was the cost of electricity for this house, apartment, or mobile home? How many times has this person been married?
After each question, the Bureau of the Census provides a statement of how the answer meets a federal need. I would prefer that they provide a statement of how answers to the questions meet the constitutional need as expressed in Article I, Section 2 of the U.S. Constitution.
