1850 United States Census
The United States Census of 1850 was the seventh census of the United States. Conducted by the Census Office on June 1, 1850, 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.
This was the first census where there was an attempt to collect information about every member of every household, including women, children, and slaves. 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.). It was also the first census to ask about place of birth.

The 1850 United States Census collected a great amount of data that gave insight into the state of the U.S. economy in 1850. Some of the data revealed the growth of the economy with regards to agricultural and manufactured production, international trade, federal debt, taxation, transportation, education, and land expansion.
- Agricultural Production
- This census calculated the total land by state (in square miles), the total production of major goods and livestock per state (in respective units), the total value of each good produced, the total number of plantations per state, and various other statistics. The total agricultural production between in 1850 was calculated at about 1.3 billion dollars.
- Manufactured Production
- This census included the total manufactured production (in dollars), the total amount of capital invested, the total value of wages paid, the percent of profit (by state and total), the profit by state of major industries (cotton, wool, various iron work, breweries, fishing, salt), along with other less significant statistics. Total manufactured production was valued at just over one billion dollars. This is a great increase over the totals estimated in 1820 and 1840. Also, in total, the manufacturing industry recorded an overall profit of 43%.
- International Trade
- The 1850 census contains the total value of imports and exports by state, statistics and names of the major imports and exports, the total values of shipping by state, and the value of imports and exports with various individual countries. The United States traded most with Great Britain. The imports and exports with England were both valued around 145 million dollars.
- Federal Debt
- This census contains yearly federal debt totals, total federal revenues, and total expenditures from 1790-1853. The total debt of the United States on July 1, 1854 was roughly 47.2 million dollars.
- The census contains some calculation of total annual federal taxes, but it is incomplete. It does however, give state taxation totals.
- Transportation and Communication
- This census calculates the total cost, size, and quantity of railroads and canals. The funded debt for railroads and canals in 1853 was 130 million. Their gross earnings were more than 38 million dollars. This census also contains estimates for growth in mileage of telegraphic lines in the United States. In 1853 the country contains 89 telegraph lines that stretched 23,261 miles (37,435 km). When published in 1854, the country had an estimated 30,000 miles (48,000 km) of telegraphic lines, a drastic increase.
- This census displays the advances of the United States in education and literacy by documenting the number of libraries, the number of schools (public, private, and colleges), state literacy rates, the total newspaper production and consumption, the educational levels of differing races, the total value of tuition costs, the amount of federal land given for education, and other various statistics.
- Land Expansion
- The 1850 census shows the great amount of territorial expansion that took place in the United States, following the Admission of Texas, the Oregon Treaty, and the Treaty with Mexico. These three pieces of land totaled an addition of more than a million square miles to the nation. In 1850, the United States contained 31 states and 4 organized territories (Minnesota, New Mexico, Oregon, Utah).
- The 1850 United States Census can be seen as a historical document that gives insight into the state of the nation’s economy in 1850. It is much more detailed and provides more information than the 1840 census.
This census was during a very important period of growth and innovation in the United State, the Industrial Revolution. The statistics in this census provide data on the rate of growth that was taking place in 1850, that would lead to the emergence of the United States as an economic world power. Many of the statistics were compared to those of Great Britain and other world powers. This shows where the United States stood economically relative to the rest of the world.
