This is what a census looked like back in 1881. I chose this picture to illustrate how a census is organized. There's a lot of categories in this example like name, birthday, occupation, and so on. In statistics there's endless possibilities to the categories you can use in a census.(Dillon Hernandez)

census: "an official periodic count of a population including such information as sex, age, occupation, etc." (giovanni)
