Even if you don't intend to use them, it is useful to print them out simply to have a complete understanding of what information is contained in each census year.
More recent censuses contain more information than earlier ones.
Between 1790 and 1850, the ten-year censuses only obtained the name of the head of the household and listed others in the household according to sex and age categories. In 1850, the census began to list the names, ages, occupations, and birthplaces of each person. The 1880 census was the first to list the state or country of birth of each person's parent. The census also began to indicate what the relationship is among those in the same household. The 1910 census was the first to give the month and year of birth.
