- 7th Decennial Census.
- U.S. Population: 23,191,876.
- Cost: $1,423,351.
The 1850 census saw a dramatic shift in the way information about residents was collected. For the first time, free persons were listed individually instead of by family. There were two questionnaires: one for free inhabitants and one for slaves.
Schedule No. 1 - Free Inhabitants
Listed by column number, enumerators recorded the following information:
- Number of dwelling house (in order visited)
- Number of family (in order visited)
This column was to be left blank if a person was White, marked "B" if a person was Black, and marked "M" if a person was Mulatto.
- Profession, occupation, or trade of each person over 15 years of age
- Value of real estate owned by person
- Place of Birth
If a person was born in the United States, the enumerator was to enter the state they were born in. If the person was born outside of the United States, the enumerator was to enter their native country.
- Was the person married within the last year?
- Was the person at school within the last year?
- If this person was over 20 years of age, could they not read and write?
- Is the person "deaf, dumb, blind, insane, idiotic, pauper, or convict?"
Schedule No. 2 - Slave Inhabitants
Slaves were listed by owner, not individually. Listed by column number, enumerators recorded the following information:
- Name of owner
- Number of slave
Each owner's slave was only assigned a number, not a name. Numbering restarted with each new owner
This column was to be marked with a "B" if the slave was Black and an "M" if they were Mulatto.
- Listed in the same row as the owner, the number of uncaught escaped slaves in the past year
- Listed in the same row as the owner, the number of slaves freed from bondage in the past year
- Is the slave "deaf and dumb, blind, insane, or idiotic?"
