Let's clarify things. I do not recommend removing questions because there should be as many questions as possible. Ideally, all necessary questions should be there. The most important message is that constitutional rights depend on questions that are not in the census. So we must add them. They have to be in the mandatory form. For things to work, those questions have to be submitted to 100% of the population.
