I really dont understand why people get so bent out of shape over the census form. Unless you've got something to hide, why complain about filling in a silly little form once a year.
If the census form was anonomous I would gladly fill it in but why do they need names, DOBs, and other personal details like the address of your work place?
I haven't filled it in and have no intention of filling it in. Had the census people round ab out three times once I wasn't in and the other two times I didn't answer my door to them.
