1850 United States census

Although the official date of the census date was June 1, 1850,^[1] completed census forms indicate that the surveys continued to be made throughout the rest of the year.^[2][3]


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 (three children under age five, one woman between the age of 35 and 40, etc.). This was also the first census to ask about place of birth of free residents.


Hinton Rowan Helper made extensive use of the 1850 census results in his influential anti-slavery book The Impending Crisis of the South (1857).

The 1850 census, Schedule 1, Free Inhabitants, collected the following information:^[4]

Data availability[edit]

Microdata from the 1850 population census are freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System.

Controversy[edit]

The Utah Territorial census was taken in 1851. Secretary Broughton Harris refused to certify the census of Utah territory. Harris complained that Brigham Young had conducted the census without him, claimed several irregularities, and consequently withheld funds reserved for the census.^[11] The controversy contributed to Harris' decision to join other Runaway Officials of 1851 and abandon his post in Utah Territory. Relationships with the federal government continued to sour and eventually resulted in the Utah War.


Local government officials feared having an enslaved population might impede the territory's quest for statehood, since certain members of Congress were concerned about expansion of slavery into the western territories.^[12] The 1850 census slave schedule for Utah Territory reported only 26 slaves, with a note that all of them were heading to California, and did not include any enslaved people remaining in the territory.^[13] John David Smith estimates that there were 100 blacks in Utah by 1850, with two-thirds of them enslaved.^[14]
