My form had 10 questions. None of which I deemed to be personal. Nothing like the information companies and marketing firms have been gathering from you for years. The census is taken so that they can track the population movement throughout the country. By doing so they have guidelines for resetting Congressional districts and awarding monies for education and other needs to states according to population. All the hype about it is just that hype. It is an important part of how things are done not some scheme to keep an eye on you. My sister found our grandfather who left for California when our father was about ten by reading the census documentation for the few years after he left.
