The Seventeenth Census: Census Day was April 1, 1950.

Enumeration

The 1950 census encompassed the continental United States, the territories of Alaska and Hawaii, American Samoa, the Canal Zone, Guam, Puerto Rico, the Virgin Islands of the United States, and some of the smaller island territories.

Americans abroad were enumerated for the first time in 1950. Provisions were made to count members of the armed forces, crews of vessels, and employees of the United States government living in foreign countries, along with any members of their families also abroad. This enumeration was carried out through cooperative arrangements with the departments of Defense and State, the United States Maritime Administration and other federal agencies that took responsibility for distributing and collecting specially designed questionnaires.

Other persons living abroad were to be reported by their families or neighbors in the United States, but the quality of these data was considered to be poor and they were not included in the published statistics.

A new survey on residential financing was conducted as part of the 1950 census. In a separate operation, information was collected on a sample basis from owners of owner-occupied and rental properties and mortgage lenders.

Efforts to Improve Coverage and Completeness

Several procedures were used to improve the accuracy and completeness of the 1950 census, including: improved enumerator training, providing enumerators with detailed street maps of their assigned areas, publishing “Missed Person” forms in local newspapers, and setting a specific night to conduct a special enumeration of persons in hotels, tourist courts, and other places frequented by transients.

For the first time, a post-enumeration survey was instituted as a further check on the accuracy and completeness of the count. The Census Bureau recanvassed a sample of about 3,500 small areas and compared these to the original census listings to identify households that may have been omitted in the original enumeration. In addition, a sample of about 22,000 households was reinterviewed to determine the number of persons likely omitted in the initial count.

Technological Advancement

The Census Bureau began use of the first non-military computer shortly after completing the 1950 enumeration. UNIVAC I (for Universal Automatic Computer), the first of a series, was delivered in 1951, and helped tabulate some of the statistics for the 1954 economic censuses. It weighed 16,000 pounds and used 5,000 vacuum tubes.

Intercensal Activity

In August of 1954, Congress codified the various statutes, including 1929’s Fifteenth Census Act, which authorized the decennial and other censuses, as Title 13, US Code. Since then, Title 13 (along with other laws) has been the underlying authority that governs the actions of the Bureau.

The Sixteenth Census: Census Day was April 1, 1940.

Authorizing Legislation

In August 1939, Congress authorized the director of the census to conduct a national census of housing “in each state, the District of Columbia, Hawaii, Puerto Rico, the Virgin Islands, and Alaska, in the year 1940 in conjunction with, and at the same time, and as part of the population inquiry of the sixteenth decennial census.” The census was “to provide information concerning the number, characteristics (including utilities and equipment), and geographic distribution of dwelling structures and dwelling units in the United States.”

Enumeration

Because the originating legislation came so late in the census planning process and because the nature of the questions was so different from those in the census of population, the housing inquiries in the 1940 census were collected via a separate census. In practice, enumerators collected information for the housing census at the same time they collected information for the population census.

Sampling

One of the major innovations of the 1940 census was the use of advanced statistical techniques, including probability sampling, which had been used only on an experimental basis before. Sampling had been tested in a trial census of unemployment carried out by the Civil Works Administration in 1933-1934 and surveys of retail stores in the same decade, and an official sample survey of unemployment in 1937 that covered about 20,000 households.

Sampling in the 1940 census allowed the addition of a number of demographic questions of enumerated persons without unduly increasing the overall burden on respondents and on data processing. It also made it possible to publish preliminary returns 8 months ahead of the complete tabulations. Sampling also allowed the Census Bureau to increase the number of detailed tables published and review the quality of the data processing with more efficiency.

Several new questions reflected the concerns of the depression years. Along with the new census focusing on the condition of the nation’s housing stock and the need for public housing programs, the 1940 census included questions about employment, unemployment, internal migration and income.

The Fifteenth Census: Census Day was April 1, 1930.

Authorizing Legislation

The Fifteenth Census Act, approved June 18, 1929, authorized “a census of population, agriculture, irrigation, drainage, distribution, unemployment, and mines [to be] taken by the Director of the Census.” This act was the first to specify only general areas to be investigated, leaving the content of specific questions to the discretion of the director. The census encompassed each state, along with Washington, DC, Alaska, Hawaii, and Puerto Rico. The governors of Guam, American Samoa, and the Virgin Islands each completed a census that same year. So did the governor of the Panama Canal Zone.

Crises and Controversies

In the time between the passage of the act and census day, the stock market crashed and the nation plunged into the Great Depression. The public and academics wanted quick access to the unemployment information collected in the 1930 census. The Census Bureau had not planned to process the unemployment information it had collected – which some statisticians considered unreliable – until quite a bit later and was unequipped to meet these demands. When it did rush its data on unemployment out, the numbers it reported were attacked as being too low. Congress required a special unemployment census for January 1931; the data it produced confirmed the severity of the situation.

Intercensal Activity

Congress mandated that another unemployment census be conducted in 1937. This special census was largely voluntary; postal carriers delivered a form to every residential address in the country and those who were unemployed were expected to fill it out and mail it back. This special census is noteworthy because it was an early opportunity for Census Bureau statisticians to experiment with statistical sampling. Two percent of households were delivered a special census questionnaire whose results were used to test the accuracy of the larger census.

The Fourteenth Census: Census Day was January 1, 1920.

Authorizing Legislation

The date change for the 1920 census was requested by the Department of Agriculture. The department believed that in January, harvests would be completed and information about those harvests would still be fresh in farmers’ minds. Additionally, it argued that more people would be at home in January than in April.

The census act designated a three-year decennial census period, beginning July 1, 1919, during which time the Census Bureau was authorized to hire an increased work force at its Washington, DC headquarters and created a special field force to collect the data.

The act also authorized a census of manufactures to be taken in 1921, repeated every two years thereafter. Previously, the manufacturing census had been conducted every five years. The act further ordered a census of agriculture and livestock in 1925, repeated every ten years thereafter, and strengthened for penalties for those who refused to supply information or who supplied false information. These censuses, which had once been closely aligned with the decennial population count, were, by 1920, largely independent of each other.

The act also stipulated that the director could, at his discretion, furnish any governor or court with certified copies of census returns at the cost of making the search plus one dollar for certification. Individuals who wanted copies for genealogical or other purposes could also obtain them, so long as the information was not used to the detriment of the person to whom the information referred.

Enumeration

For the 1920 census, “usual place of abode” became the basis for enumeration. Individuals were enumerated as residents of the place in which they regularly slept, not where they worked or might be visiting. People with no regular residence, including “floaters” and members of transient railroad or construction camps, were enumerated as residents of the place where they were when the count was taken. Enumerators were also instructed to ask if any family members were temporarily absent; if so, these people were to be listed either with the household or on the last schedule for the census subdivision.

The format and information in the 1920 census schedules closely resembled that of the 1910 census. The 1920 census, however, did not ask about unemployment on the day of the census, nor did it ask about service in the Union or Confederate army or navy. Questions about the number of children born and how long a couple had been married were also omitted. The bureau modified the enumeration of inmates of institutions and dependent, defective, and delinquent classes. The 1920 census included four new questions: one asking the year of naturalization and three about mother tongue. There was no separate schedule for Indians in 1920.

Because of the changes in some international boundaries following World War I, enumerators were instructed to report the province (state or region) or city of persons declaring they or their parents had been born in Austria-Hungary, Germany, Russia, or Turkey. If a person had been born in any other foreign country, only the name of the country was to be entered.

The instructions to enumerators did not require that individuals spell out their names. Enumerators wrote down the information given to them; they were not authorized to request proof of age, date of arrival, or other information. The determination of race was based on the enumerator’s impressions.

Intercensal Activity

The results of the 1920 census revealed a major and continuing shift of the population of the United States from rural to urban areas. No apportionment was carried out following the 1920 census; representatives elected from rural districts worked to derail the process, fearful of losing political power to the cities. Reapportionment legislation was repeatedly delayed as rural interests tried to come up with mechanisms that would blunt the impact of the population shift. Congress finally passed a reapportionment bill in 1929. The bill declared that the House of Representatives would be apportioned based on the results of the 1930 census.

The 1929 act provided for an automatic reapportionment by the last method used unless Congress moved proactively to prevent that from occurring. The act also authorized the 1930 and subsequent decennial censuses.

The Thirteenth Census: Census Day was April 15, 1910.

Authorizing Legislation

Legislation for the 1910 census was introduced initially in December 1907, but was not enacted into law until July 1909. The delay resulted from a disagreement over the appointment of enumerators, with President Theodore Roosevelt insisting that they be hired through the civil service system and Congress seeking to retain them as patronage positions, as had been traditional. Roosevelt won this fight.

One new feature of the 1910 act was that it changed Census Day from June 1st, which it had been since 1830, to April 15. The director of the Census Bureau suggested this adjustment, because he felt that much of the urban population would be absent from their homes on summer vacations in June.

The act also did away with vital statistics inquiries on the questionnaire, but added questions about mines and quarries. A month before the census, an amendment to the act required an additional question on nationality or mother tongue of foreign-born persons and their parents. Because the questionnaires had already been printed, enumerators were instructed to add this information to column 12 (birthplace) of the form.

The enabling legislation for the 1910 census authorized funds for the newly established permanent Census Bureau to expand its permanent workforce and specifically created several new full-time positions, including that of a geographer, a chief statistician, and an assistant director. The assistant director, appointed by the president with the advice and consent of the Senate, was to be an experienced practical statistician. All non-presidentially-appointed census employees were hired on the basis of their scores in open, competitive examinations, administered throughout the country by the Civil Service Commission.

Enumeration

For the first time, enumerators in the large cities distributed questionnaires in advance, a day or two prior to April 15, so that people could become familiar with the questions and have time to prepare their answers. In practice, only a small portion of the population filled out their questionnaires before the enumerator visit, however. The law gave census takers two weeks to complete their work in cities of 5,000 inhabitants or more while enumerators in smaller and rural areas were allotted 30 days to complete their task.

Crises and Controversies

Difficulties with the tabulation process continued despite the presence of automatic counting machinery introduced in the most recent censuses. Correcting these problems delayed publication of some population numbers. Some census results, such as the total population of cities, were issued first as brief press releases, but were expanded into bulletins and abstracts that appeared as long as a year before the final reports were published.

Intercensal Activity

When the United States entered World War I in 1917, the Census Bureau took on an important new role. During the nation’s mobilization for the war, the Census Bureau was able to use its compiled population and economic data to report on populations of draft-age men, along with the different states’ industrial capacities.

The Twelfth Census: Census Day was June 1, 1900.

Authorizing Legislation

In the act authorizing the 1900 census, Congress limited census content to questions dealing with population, mortality, agriculture, and manufacturing. Reports on these topics, called “Census Reports,” were to be published by June 30, 1902. The act also authorized special census agents to collect statistics relating to incidents of deafness, blindness, insanity, juvenile delinquency, and the like; as well as on religious bodies; utilities; mining; and transportation, among others. These statistics were to be collected following the completion of the regular census. The preparation of the special reports developed from these statistics was to be accomplished in such a way so as to not interfere with the completion of the Census Reports.

The act also changed the title of the chief officer of the Census Office from “supervising clerk of the census” to “director of the census.” Additionally, a new position, assistant director of the census, to be filled by “an experienced practical statistician,” was established. The director was given the power to appoint staff based on noncompetitive examinations. However, in practice, positions were given to political referrals.

Enumeration

The Departments of War and the Navy enumerated military personnel (including those who were abroad). Indian Territory was enumerated with the cooperation of the commissioner of Indian affairs.

Hawaii, which had been annexed in 1898, was included in the census for the first time. (A census of Puerto Rico and Cuba had been carried out by the War Department in 1899. Under the direction of the Philippine Commission, a census of that territory was taken in 1903.)

Intercensal Activity

In 1902, the formerly temporary Census Office was made a permanent organization within the Department of the Interior. In 1903, it became the Census Bureau and was moved to the new Department of Commerce and Labor.

The transition from a temporary to a permanent agency was sometimes controversial. One of Congress’s goals in creating the new department was to centralize many of the overlapping statistical offices scattered throughout the bureaucracy; Census Bureau officials attempted, without much early success, to assume the role as chief statistical agency of the federal government. These aspirations were hindered, in part, by the Census Bureau’s subordinate position within the Department of Commerce and Labor.

The Eleventh Census: Census Day was June 2, 1890.

Authorizing Legislation

An act signed into law March 1, 1889 authorized the census of 1890, which was modeled after the 1880 enumeration.

Enumeration

Because June 1 was a Sunday, the 1890 enumeration began on June 2. The census employed 175 supervisors, with one or more appointed to each state or territory, except Alaska and the Indian Territory. Subdivisions assigned to a single enumerator were not to exceed 4,000 inhabitants. In cities designated by 1880 census results to have populations under 10,000, the enumeration was to be completed within two weeks. Enumerators were required to collect all information required by the act by a personal visit to each dwelling and family.

The 1890 questionnaire retained almost all of the inquiries from the 1880 census, and a few new questions were added. The 1890 census included a greater number of subjects than any previous census and more than would be included in those immediately following. New entries included questions about ownership and indebtedness of farms and homes; the names, as well as units served in, length of service and residences of surviving Union soldiers and sailors and the names of the widows of those who had died. Another new question dealt with race, including “Japanese” as a category for the first time, along with “Chinese,” “Negro,” “mulatto,” “quadroon,” “octoroon,” and “white.”

The population schedule was changed so that a separate sheet was used for each family, irrespective of the number of persons included.

As in 1880, experts and special agents were hired to make special enumerations of manufactures, Indians living within the jurisdiction of the United States, and a separate enumeration of Alaska. Furthermore, the schedule collecting social statistics was withdrawn from enumerators; the work of obtaining statistics concerning mines and mining, fisheries, churches, education, insurance, transportation, and wealth, debt, and taxation, also was conducted by experts and special agents.

For the first time, enumerators were given detailed maps to follow so they could account for every street or road and not stray beyond their assigned boundaries.

Technological Advancement

The 1890 census was notable as the first in which the electric tabulating system, invented by former Census Office employee Herman Hollerith, was used. Tabulation of the 1880 census results took almost a decade to complete, and officials hoped Hollerith’s machine would alleviate delays caused by relying on hand counts and rudimentary tallying machines to process data.

Hollerith’s machine required information from the census questionnaires to be transferred to a card, which was hole-punched at various places to indicate the characteristics – age, sex, color, marital status, etc. – of a person enumerated. The cards were then run through an electronic tabulating machine, which, using metal pins to complete circuits through the punched holes, counted or cross-tabulated different characteristics.

Intercensal Activity

Robert P. Porter served as superintendent of census until his resignation on July 31, 1893. On October 3, 1893, Congress enacted a law that directed census-related work to continue under the direction of the commissioner of labor. On March 2, 1895, a further act of Congress closed the Census Office and transferred the unfinished work to the office of the secretary of the interior, where it continued until July 1, 1897.

The Tenth Census: Census Day was June 1, 1880.

Authorizing Legislation

The act authorizing the 1880 census gave supervision of the enumeration to a body of officers, known as supervisors of the census, who were specifically chosen for work on the census. The superintendent of the census and all supervisors were to be presidential appointees, subject to Senate confirmation. The terms of both were to expire when the census results were compiled and published.

Enumeration

Each supervisor was responsible for recommending the organization of his district for enumeration, choosing enumerators for the district and supervising their work, reviewing and transmitting the returns from the enumerators to the central census office, and overseeing the compensation for enumerators in each district.

The census act required each enumerator “to visit personally each dwelling house in his sub-division, and each family therein, and each individual living out of a family in any place of abode, and by inquiry made of the head of such family, or of the member there of deemed most credible and worthy of trust, or of such individual living out of a family, to obtain each and every item of information and all the particulars.” In case no one was available at a family’s usual place of abode, the enumerator was directed by the law “to obtain the required information, as nearly as may be practicable, from the family or families, or person or persons, living nearest to such place of abode.”

The census act also provided for the collection of detailed data on the condition and operation of railroad corporations, incorporated express companies, and telegraph companies, and of life, fire, and marine insurance companies (using Schedule No.4 – Social Statistics). Fines were to be imposed on officials of “every corporation…who shall…willfully neglect or refuse to give true and complete answers to any inquiries authorized by this act.”

In addition, the superintendent of census was required to collect and publish statistics of the population, industries, and resources of Alaska, with as much detail as was practical. An enumeration was also made of all untaxed Indians within the jurisdiction of the United States.

The 1880 decennial census was taken on five schedules: “Population,” “Mortality,” “Agriculture,” “Social Statistics,” and “Manufacturing.”

The Ninth Census: Census Day was June 1, 1870.

Authorizing Legislation

The 1870 Census was conducted under the authority of the Census Act of 1850. A new law, approved on May 6, 1870, called for two procedural changes: The marshals were to submit the returns from the population questionnaire to the Census Office by September 10, 1870; all other questionnaires were due by October 1, 1870. Additionally, penalties for refusing to reply to enumerator inquiries were expanded to cover all questions asked on all questionnaires.

Enumeration

The Census Office, and the position of superintending clerk were abolished in May 1865. A portion of the clerks engaged in census work transferred to the General Land Office, where work of the 1860 census was completed under the direction of the commissioner of the General Land Office

After the Civil War, the decennial census questionnaires were reordered and redesigned to account for end of the “slave questionnaire.” The schedules for the 1870 census were: “General Population,” “Mortality,” “Agriculture,” “Products of Industry,” and “Social Statistics.”

The secretary of interior selected General Francis A. Walker as superintendent of the ninth census on February 7, 1870. At the time of his appointment General Walker was chief of the Bureau of Statistics – an agency within the Treasury Department – and was one of several experts who had participated in the U.S. House of Representatives’ committee deliberations on the 1870 census. A capable administrator, Walker introduced examinations to test the qualifications of those applying for positions with the Census Office. Walker remained as superintendent until November 1871, when Congress’s failure to appropriate funds for his salary caused him to resign. Nevertheless, he continued overseeing census work as commissioner of Indian Affairs. Later, he resumed his duties as superintendent of the census, working without compensation.

The 1870 enumeration was completed by August 23, 1871.

Technological Advancement

By 1870, the job of tallying and tabulating questionnaire responses was becoming overly burdensome for the Census Office. This problem was partially alleviated with the use of a rudimentary tallying machine, invented by the chief clerk of the Census Office, and later superintendent, Charles W. Seaton.

The Eighth Census: Census Day was June 1, 1860.

Authorizing Legislation

The 1850 Census Act was the authorizing legislation for the 1860 census. That act had stipulated that, according to the recommendation of the secretary of the interior, its provisions were to be adhered to for all future decennial censuses if no new authorizing legislation was passed by January 1 of the year in which the census was required.

Intercensal Activity

The Census Office, and the position of superintending clerk were abolished in May 1865. A portion of the clerks engaged in census work transferred to the General Land Office, where work of the 1860 census was completed under the direction of the commissioner of the General Land Office

The Seventh Census: Census Day was June 1, 1850.

Authorizing Legislation

The Census Act of 1840 (signed into law on March 3, 1839 and amended by an act of February 26, 1840) authorized establishing a centralized census office during each enumeration. Congress left the design of the questionnaire to the discretion of the secretary of state, but specified that inquiries be made of each household. Subjects among the inquiries were to include “the pursuits, industry, education, and resources of the country.” New population inquiries included questions about school attendance, literacy, and vocation. In March 1849, Congress enacted a bill establishing a census board whose membership consisted of the secretary of state, the attorney general, and the postmaster general. The law authorized this board to prepare and cause to be printed such forms and schedules as may be necessary for the full enumeration of the inhabitants of the United States; it also authorized the board to prepare forms and schedules for collecting information on mines, agriculture, commerce, manufactures, education, and other topics, as well as “exhibit a full view of the pursuits, industry, education, and resources of the country.”

The seventh census was governed by the provisions of an act of May 23, 1850 that directed that six schedules be used to collect the information requested by the Congress. The act directed enumerators to return their results to the secretary of the interior by November 1, 1850.

Enumeration

The number of population inquiries grew in the 1850 census. Every free person’s name was to be listed, not just the head of the household. The marshals also collected additional “social statistics,” including information on taxes, schools, crime, wages, value of the estate, etc. and data on mortality.

Each marshal was also responsible for subdividing his district into “known civil divisions,” such as counties, townships, or wards, and ensuring that his assistants’ returns were completed properly.

The Sixth Census: Census Day was June 1, 1840.

Authorizing Legislation

The Census Act of 1840 (signed into law on March 3, 1839 and amended by an act of February 26, 1840) authorized establishing a centralized census office during each enumeration. Congress left the design of the questionnaire to the discretion of the secretary of state, but specified that inquiries be made of each household. Subjects among the inquiries were to include “the pursuits, industry, education, and resources of the country.” New population inquiries included questions about school attendance, literacy, and vocation.

Enumeration

The administration of the sixth census was very similar to that of the fifth. Enumeration began on June 1, 1840. Marshals were to receive two copies of the census receipts from enumerators by November 1, 1840, one of which was to be sent to the secretary of state by December 1, 1840.
