Your Family Tree has a sample image from the 1911 UK census. Let's hope your British ancestors had good penmanship.
Unlike the pages you'll see for the 1901 Census and before, these schedules were completed by the householders themselves, rather than the enumerators. One of the most exciting things, then, is that when you find a census page relating to an ancestor, you'll be able to see their actual signature at the bottom right if they were head of the household.
