According to updated numbers released by the U.S. Census Bureau today, 99.98% of all housing units and addresses nationwide were accounted for in the 2020 Census as of the end of self-response and field data collection operations on Oct. 15, 2020. In all states, the District of Columbia and the Commonwealth of Puerto Rico, more than 99% of all addresses have been accounted for, and in all but one state that number tops 99.9%.

“The 2020 Census faced challenges like no other decennial census in living memory,” said Secretary of Commerce Wilbur L. Ross, Jr. “Achieving these metrics in the face of severe weather events and a global pandemic is a testament to the determination and ingenuity of the hundreds of thousands of dedicated women and men who worked on the 2020 Census.”

Compared to the final self-response rate of 66.5% for the 2010 Census, 67% were accounted for through self-response to date, with the rest having been accounted for through our Nonresponse Followup (NRFU) operation.

“America stepped up and answered the call: shape your future by responding to the 2020 Census,” said Dr. Steven Dillingham, Director of the Census Bureau. “Generally, better data comes from self-response, but after a decade of global decline in census and survey participation along with the challenges presented to communities by COVID-19, we had not expected to exceed the 2010 self-response rate. That we did is a testament to the American people, our nearly 400,000 national and community partners, and very importantly our staff.”

“The Census Bureau was able to meet and overcome many challenges because of our innovative design and use of new technology, but it could not be done without the unflinching resolve of our staff,” Dillingham continued. “We thank everyone on the team for their contributions, from the census takers and field staff going the extra mile to reach those hardest to count, to the dedicated operational leadership at headquarters and around the country working around the clock to maintain and protect our systems, process the data, oversee the operation, and get the word out about the importance of the 2020 Census.”

“We are especially proud of the hard work done to bring the state of Louisiana over 99% complete despite the devastating effects of hurricanes Laura and Delta, and of the partnership with American Indian and Alaska Native tribal governments to get 99.77% of the NRFU workload on their lands done, despite closures due to the pandemic.”

“Hundreds of millions of people were counted in the 2020 Census, and statisticians and data quality experts are now busy making sure everyone was counted once, only once, and in the right place,” Dillingham continued. “The Census Bureau will use the best methodologies available to resolve the very small number of unresolved addresses and to ensure that our data products are accurate.”

Each census, the Census Bureau produces coverage estimates and conduct extensive assessments that we share with the public. The completion rates are just early indicators. For more information on the 2020 Census, including use of proxy and administrative records, please see our updated FAQs.

The Census Bureau is working hard to process the data in order to deliver complete and accurate state population counts as close as possible to the Dec. 31, 2020, statutory deadline.

Data collection for the 2020 Census ended at 11:59 p.m. Hawaii Standard Time on Oct. 15, 2020 (5:59 a.m. EDT). Paper responses are still arriving and will be processed if postmarked by October 15, and received at the processing center no later than October 22.

Nebraska is still FIRST in Census responses in our region! Here’s all the latest news from the Census Bureau:

The Twenty-Third Census: Census Day was April 1, 2010.

Enumeration

The 2010 census questionnaire was one of the shortest in history – asking just 10 questions of all households in the United States and Island Areas related to name, gender, age, race, ethnicity, relationship, and whether you own or rent your home. Collection of data about education, housing, jobs, etc. collected by previous censuses long-form questionnaires are now collected by the U.S. Census Bureau’s annual American Community Survey.

In addition to the reduced number of questions, the Census Bureau announced it would count same-sex married couples in June 2009. When noting the relationship between household members, same-sex couples who are married could mark their spouses as being “Husband or wife”, the same response given by opposite-sex married couples. An “unmarried partner” option was available for couples (whether same-sex or opposite-sex) who were not married.

Marketing and Promotional Efforts

Following the success of Census 2000’s advertising, the 2010 census featured a $133 million, 4-month advertising campaign. Although officially beginning January 18, 2010, the advertising campaign debuted the night of January 17 during NBC’s Golden Globe Awards broadcast.

In total, the 2010 advertising campaign included television, radio, print, outdoor and the Internet advertising, produced in an unprecedented 28 languages. More than half of the budgeted advertising would target media consumed by minority and ethnic audiences. The Census Bureau anticipated that the campaign would reach the average person 42 times with messages about the importance of participating in the census.

From Super Bowl XLIV and the 2010 Winter Olympics, to popular primetime shows, the 2010 Census advertising campaign represented the most extensive and diverse outreach campaign in U.S. history. The advertising rollout also included updates on other outreach efforts, such as the Census in Schools program, “Portrait of America” Road Tour, and the national and regional partnership programs targeted at reaching hard-to-count populations.

Other key elements of the 2010 Census Integrated Communications Campaign included:

• A national road tour with 13 vehicles traveling to key events across the country, such as NASCAR races, the Super Bowl, and parades.
• A 2010 Census Web Site.
• “Teach Census Week” in schools nationwide in February, part of the Census in Schools program.
• Nationally broadcasted public service announcements airing nationwide.
• Outreach activities launched by national and local corporate, foundation, government, and nonprofit organizations.

The Twenty-Second Census: Census Day was April 1, 2000.

Enumeration

The short form contained only seven questions, the shortest census questionnaire since 1820. The long form asked 52 questions of approximately 1 in 6 households (approximately a 17 percent sample of the population). In previous censuses, responses to the race question were limited to a single category; in 2000, for the first time, respondents could check as many boxes as necessary to identify their race. A 1996 law mandated a new question on grandparents as care givers. Questions on disability were expanded to include hearing and vision impairment and problems with learning, remembering or concentrating. Questions on children ever born, source of water, sewage disposal and condominium status, were dropped; the 1990 census short form question on rent and property value became a long form question.

Efforts to Improve Participation

To counter a decline in the questionnaire mail-back rate, the Census Bureau embarked on an aggressive paid advertising campaign, awarding a $167 million contract to the Young and Rubicam Company for national and local print, television and public advertising campaign. This campaign consisted of more than 250 television, print, radio, outdoor, and other advertisements in 17 languages; it reached 99 percent of all U.S. residents. By the end of the campaign, the census message – “This is your future. Don’t leave it blank.” – had been seen or heard an average of 50 times per person. This campaign, along with an aggressive non-response follow-up program, brought the mail-back rate up to about 67 percent.

There were additional options for responding to the census. People receiving the short form could respond on the Internet, and about 70,000 households did so. Telephone questionnaire assistance centers provided questionnaire help in 6 languages and took responses to the short form over the phone.’

Reengineered Census Plan for 2000

Following the costly litigation generated by the 1980 and 1990 censuses, particularly that which sought statistical adjustment of the census counts to correct for persons estimated to have been missed or duplicated, the Census Bureau designed a plan for the 2000 census that it believed would eliminate the possibility of litigation. The Census Bureau’s May 1995 plan for a “reengineered census” was the culmination of a four-year process of discussion and review of census plans by a broad spectrum of experts, advisors, and stakeholders. The plan was further refined and on February 28, 1996, Commerce and Census Bureau officials made public.

The Plan for Census 2000

The plan called for using statistical sampling techniques in two principal ways. The first was to alter the traditional 100-percent personal visit of non-responding households during nonresponse followup (NRFU). Instead, a small percentage of non-responding households would be followed up on a sample basis. Information from this sample would be used to estimate the number of persons and their characteristics in the remaining non-responding households.

The second involved the Census Bureau taking a sample of 750,000 housing units to be matched to housing unit questionnaires obtained from mail and telephone responses as well as personal visits. The goal of this quality check survey was to develop adjustment factors for persons estimated to have been missed or duplicated in the census and correct the census counts to produce one set of numbers. This was to be a “one-number census,” corrected for net coverage errors, that is, Integrated Coverage Measurement (ICM). ICM was a significant departure from 1990, when the results of the post-enumeration survey (PES) were used to produce a separate set of statistically adjusted counts after the delivery of the apportionment counts and redistricting data. This resulted in two competing sets of population numbers.

Congressional Opposition to the Census 2000 Plan

Beginning with the fiscal year (FY) 1997 appropriations process, the congressional majority included language in appropriations legislation that would prohibit the use of sampling in Census 2000 or the expenditure of funds for Census 2000 sampling-related planning activities.

Debate over the sampling issue postponed passage of the Commerce Department’s FY 1998 appropriations bill until the end of November 1997, two months into the new fiscal year. With the threat of a stalemate between the congressional leadership and the Clinton administration in the debate over the use of statistical sampling in Census 2000, the two sides reached a compromise in the enacted legislation. The legislation, among other things, permitted the Census Bureau to continue to plan for sampling, while directing the agency to plan for a census without statistical sampling. This was later referred to as “dual-track” planning.

The law also set up an eight-member “Census Monitoring Board” to observe and monitor all aspects of the planning and implementation of Census 2000.

Litigation and Revision to the Census 2000 Plan

Two lawsuits were filed in February 1998 – including one filed by the U.S. House of Representatives – that challenged the constitutionality and legality of the planned uses of sampling to produce the apportionment counts. In both cases, the federal district courts decided for the plaintiffs. The Department of Commerce sought review of the district court decisions by the United States Supreme Court. The Supreme Court agreed to hear the cases, and oral argument took place on November 30, 1998. On January 25, 1999, the Court held in Department of Commerce v. U.S. House of Representatives that the Census Bureau’s proposed plan to use statistical sampling in the decennial census for purposes of determining congressional apportionment violates the Census Act (the Census Bureau’s authorizing statute).

Thus, the Census Bureau could no longer pursue its Census 2000 plan that included the Integrated Coverage Measurement (ICM) program and sampling for nonresponse followup. However, following the Supreme Court ruling, the Census Bureau issued a revised plan in which it stated that it planned to produce statistically adjusted data for non-apportionment uses of census data, including redistricting. But in March 2001, following the delivery of the apportionment counts, the Census Bureau recommended against the use of the adjusted data for redistricting, because of concerns regarding their accuracy. The secretary of commerce accepted the recommendation and determined that the unadjusted data would be released as the Census Bureau’s official redistricting data. In October 2001, after considering the possible use of the adjusted data for non-redistricting purposes – for example, their incorporation in the Census 2000 long-form (sample) data products – the Census Bureau director rejected the use of the adjusted data for such purposes.

Technological Advances

The Internet became the principal dissemination medium for 2000 census data. All four of the detailed data files, now called Summary Files, were available to be downloaded as soon as they were released. Individual tables could be viewed through the Census Bureau’s online database, known as the American FactFinder. Additionally these files were available for purchase on CD-ROM and DVD. The number of printed publications was reduced and the number of printed pages in the report series was by about one-tenth of the 1990 census publication program.

The Twenty-First Census: Census Day was April 1, 1990.

The Census Bureau relied on extensive user consultation prior to the census to guide its efforts to refine both the long and short form questionnaires and the resulting data products. The agency held close to 100 meetings with groups including interested citizens, state agencies and legislatures, and public and private organizations throughout the country. It also solicited recommendations from federal agencies.

Enumeration

The 1990 census used two questionnaires: A short form asked 13 questions to 100 percent of the population and a long form asked 45 questions to 20 percent. Questions on the long form covered topics as diverse as marital history, carpooling arrangements, number of stories in their dwelling place, presence of elevators, and type of cooking and water-heating fuel used. Questions about the presence of air conditioning, the number of bathrooms, and type of heating equipment were dropped from the housing section of the 1990 census.

An additional question on congregate housing (such as, “Does the monthly rent include any meals?”) was added and the question on disability was revised, replacing the 1980 question on ability to use public transportation with one on ability to go outside of the home alone and to take care of personal needs.

Efforts to Improve Coverage and Completeness

Americans were alerted to the importance of responding to the 1990 census by extensive public television, radio, and print advertising. Promotion activities included local “complete count” committees, information kits and lesson plans for schools (Census in Schools), for churches, local government outreach and partnerships, and pro bono public service announcements, costing approximately $67 million.

The Census Bureau built upon its “T-Night” and “M-Night” itinerate person enumeration programs from 1980 with “S-Night” (“S” standing for Streets/Shelters). S-Night was a one-night sweep, conducted in major cities, of homeless shelters nationwide and other areas where the homeless were known to congregate. Many in the media billed this event, which took place on March 20, 1990, as a “homeless census,” although there is no way to determine the proportion of the homeless population that was counted on “S-Night.”

Following the 1980 census, the Census Bureau initiated plans to study the possibility of statistically adjusting the 1990 census to correct for the undercount. As a part of a planned post enumeration survey (PES) the Census Bureau would complete a contemporaneous survey of households and compare the results to information from the census for the same block clusters. With these data, the Census Bureau hoped to be able to develop adjustment factors to compensate for the anticipated undercount.

In October 1987, the undersecretary of commerce for economic affairs announced that, because the Commerce Department did not intend to statistically adjust the census for either undercounts or overcounts, he was canceling the Census Bureau’s adjustment-related planning activities for the 1990 census.

In November 1988, New York City and a coalition of state and local interests joined forces to file a lawsuit to compel the Census Bureau to reconsider the use of statistical adjustment of the population totals in light of the expected undercount from the 1990 census. In July 1989, the Commerce Department and the New York plaintiffs reached a partial resolution of the lawsuit. The Census Bureau would reinstate the PES (but with a smaller sample size than originally planned) and use it to produce population data that had been adjusted for the projected undercount. These data would be judged against the unadjusted data by an expert panel – the Secretary of Commerce’s Special Advisory Panel (SAP), which would provide advice on whether to adjust the 1990 population figures.

Technological Advances

The Topologically Integrated Geographic Encoding and Referencing System (TIGER), developed by the U.S. Geological Survey and the Census Bureau, was introduced for the 1990 Census. It is a computerized representation of various map features such as streets, and rivers, and census geographic boundaries and their attributes such as latitude, longitude and address ranges. TIGER was used to geographically code addresses into appropriate census geographic areas, as well as to produce the many different maps required for data collection and tabulation.

In 1985 the Census Bureau was the first government agency to make information available on CD-ROM, a new and relatively untested medium. Six years later, detailed census data, which for several decades had been available only to organizations with large mainframe computers, was made accessible by anyone with a personal computer. As in 1980, 1990 census data were available in print, on computer tape, and on microfiche. In addition to these media and CD-ROM, selected data were also made available online through two vendors of online services- DIALOG and CompuServe.

Intercensal Activities

Demographic analysis showed that the 1990 census had an estimated net undercount of 1.8%, with an appreciably larger net undercount rate for African Americans than for other residents. The PES sampled 165,000 households in 7,500 blocks, and the Census Bureau compared this data with data from the census for the same block clusters. By comparing the data from these two sources, Census Bureau statisticians were able to estimate the numbers and characteristics of those missed or improperly counted by the enumeration. From there, the statisticians developed statistically adjusted population counts down to the block level.

In June 1991, the Undercount Steering Committee, a Census Bureau group charged with advising the director on adjustment recommended using the adjusted population counts. Following this recommendation, the director herself came out in favor of adjustment. However, the undersecretary of commerce for economic affairs, who oversees the Census Bureau disagreed. The secretary of commerce’s SAP split, four votes to four.

Responding to the mixed recommendations, the secretary of commerce announced in July 1991 that he did not find the evidence in favor of using adjusted counts convincing. He decided that the 1990 census would use the unadjusted totals.

Following announcement of the secretary’s decision, the New York plaintiffs resumed their lawsuit. The federal district court decided in favor of the Department of Commerce in April 1993. Plaintiffs appealed the ruling, and the U.S. Court of Appeals rejected the district court ruling and ordered that the case be returned to the district court for further proceedings. The issue was finally taken up by the Supreme Court, which in March 1996 upheld the secretary’s decision not to adjust the 1990 census counts, but did not rule on either the legality or constitutionality of the use of statistical adjustment in producing the apportionment counts.

The Twentieth Census: Census Day was April 1, 1980.

Enumeration

Due to the success of the mail-out/mail-back questionnaire in 1970 the program was expanded for 1980 with about 95 percent of the U.S. population now enumerated in this manner.

The 1980 short form contained 7 population questions and 11 housing questions; the long form contained an additional 26 population and 10 housing inquiries. A question on Spanish or Hispanic origin or descent was added to the 100-percent questions for the first time; in 1970 this question was asked of only 5 percent of the population.

The 1980 census also included two small surveys. The Components of Inventory Change Survey obtained information on the number and characteristics of housing units that changed or stayed the same between 1973 and 1980. The Residential Finance Survey collected data on mortgages, shelter costs, selected housing characteristics and owner characteristics.

Efforts to Improve Coverage and Completeness

An extensive public service advertising campaign directed by the Census Bureau’s Census Publicity Office, which was established in 1978, focused on increasing the public’s awareness of the census and encouraging people to complete and mail back their questionnaires. The Census Bureau secured the free services of the Advertising Council, which in turn hired the firm of Ogilvy & Mather to develop the campaign.

Additionally, the Census Bureau made a special effort to enumerate historically undercounted groups during two programs, “M-Night” (“M” for mission) and “T-Night” (“T” for transient). On M-Night, specially trained enumerators counted people staying in homeless shelters, soup kitchens, bus and rail stations, dormitories, and others. On T-Night, the enumeration focused on hotels and motels with permanent residents.

Technological Advances

The Census Bureau developed the State Data Center Program to simplify public access to data available on computer tapes. Agreements between state governors and the director of the Census Bureau committed the agency to provide free copies of any Census Bureau electronic and printed information and products to the states; the states, in turn, agreed to develop a network of affiliate organizations (state executive departments, chambers of commerce, councils of governments, university research departments or libraries) by which census information would be delivered to local users. By the mid-1980’s all states were participating in the program, which encompassed about 1,200 state and local organizations.

Intercensal Activities

Demographic analysis of the 1980 census showed that once again the census, despite reaching the overwhelming majority of people in the United States, undercounted the population, this time by about 1.2 percent. More troubling, the estimated net undercount rate for African Americans was 3.7 percentage points higher than that for all other races combined.

Before the enumeration process had finished, the city of Detroit sued, demanding that statistical adjustment be used to compensate for those estimated by the Census Bureau to have been missed or improperly counted. Shortly thereafter, several other states and localities, including the city and state of New York, also filed suit. The Census Bureau announced in the fall of 1980 that it did not plan to adjust its population totals using statistical methods because it could not be sure of the number and distribution of illegal aliens and other undercounted groups.

The New York suit would eventually become the most prominent case; a federal district court ruled in the plaintiffs’ favor in late 1980, ordering the Census Bureau to adjust its numbers to correct for the undercount. The Supreme Court stayed this and other rulings in December 1980, allowing the Census Bureau to report its unadjusted figures to the president. A federal appeals court finally ruled, in 1987, that the census figures should not be adjusted to account for the undercount because the Census Bureau’s decision not to adjust was not arbitrary and capricious.
