I think the census is a valuable tool to us family searches, however, I feel that some information is not their business. I like to see name, month/year born, relationship to head of house hold, state born, parents born, year married, if own or rent (that is neat to see on some 4th gen grandparents) occupation (is neat too, I found a 4th gen relative that was a vulanizer...I had to figure out what that was, as it was before star trek, lol) etc. But your right, they don't need to know when you leave for work. Or what you had for breakfast. :)
Do the census takers go everywhere, as I have yet to ever fill out a census form and I've been on my own since 95. It would be nice to know why I am missed.
