1850 Census
Note: The abbreviation “Ia.” was used for Indiana up until about 1856.
The United States Census of 1850 was the seventh census of the United States. Conducted by the Census Office, it determined the resident population of the United States to be 23,191,876, an increase of 35.9 percent over the 17,069,453 persons enumerated during the 1840 Census. The total population included 3,204,313 slaves.
Although the official date of the census date was June 1, 1850, completed census forms indicate that the surveys continued to be made throughout the rest of the year.
This was the first census where there was an attempt to collect information about every member of every household; women and children were named. Slaves were included by gender and estimated age on Slave Schedules, listed by the name of the owner. Prior to 1850, census records had recorded only the name of the head of the household and broad statistical accounting of other household members. This was also the first census to ask about place of birth of free residents. (Via Wikipedia)
