The 1830 Census was the first enumeration in which a uniform schedule was used to enumerate the inhabitants of the United States. Listed by head of household’s name, the enumeration consisted of inquiries dividing the free white population of each sex according to the number under 5 years of age, 5 to 10, 10 to 15, 15 to 20, 20 to 30, 30 to 40, 40 to 50, 50 to 60, 60 to 70, 70 to 80, 80 to 90, 90 to 100, and 100 years and upward; a classification of slaves and free colored persons, respectively, according to the number of each sex under 10 years of age, 10 to 24, 24 to 36, 36 to 55, 55 to 100, and 100 years and upward; the number of white persons and of slaves and colored persons, aged under 14 years, 14 and under 25, and 25 years and upward, who were blind, deaf and dumb, but without distinction of sex in either case; and a statement of white persons only who were aliens, i.e., foreigners not naturalized.

The year 1850 marks the first time that every member of the household was named. The resident inmates of a hotel, jail, garrison, hospital, asylum or other similar institution were reckoned as one family. The Census Board prepared and printed six schedules for the 1850 Census as follows: Schedule 1 – Free Inhabitants; Schedule 2 – Slave Inhabitants; Schedule 3- Mortality. This schedule included name, age, sex, color and place of birth on persons having died during the year ending June 1, 1850. Additional data were collected on constitutional and marital status; profession, occupation, or trade; month of death; disease or cause of death; number of days ill; and any suitable remarks. Schedule 4 – Production of Agriculture. This schedule collected data on agricultural production for the year ending June 1, 1850; Schedule 5 – Products of Industry. This schedule collected data on the products of industry for the year ending June 1, 1850, and applied to all forms of productive industry, including manufactures (except household manufactures), mining, fisheries and all kinds of mercantile, commercial, and trading businesses; Schedule 6 – Social Statistics. This schedule collected aggregate statistics for each subdivision enumerated on the following topics: valuation of real estate; annual taxes; colleges, academies, and schools; seasons and crops; libraries; newspapers and periodicals; religion; pauperism; crime; and wages.
