United States Census Bureau
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy; the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States; the Census Bureau's primary mission is conducting the U. S. Census every ten years, which allocates the seats of the U. S. House of Representatives to the states based on their population; the Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, transportation infrastructure, police and fire departments. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, the Current Population Survey.
Furthermore and foreign trade indicators released by the federal government contain data produced by the Census Bureau. Article One of the United States Constitution directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College; the Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population projections. In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education and more; the Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.
The Census Bureau conducts surveys on behalf of various federal government and local government agencies on topics such as employment, health, consumer expenditures, housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial population counts; the Census Bureau conducts economic surveys of manufacturing, retail and other establishments and of domestic governments. Between 1790 and 1840, the census was taken by marshals of the judicial districts; the Census Act of 1840 established a central office. Several acts followed that revised and authorized new censuses at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior, in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor; the department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years.
In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code. By law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year; the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis". The Census Bureau definition is pervasive. Regional divisions used by the United States Census Bureau: Region 1: Northeast Division 1: New England Division 2: Mid-Atlantic Region 2: Midwest Division 3: East North Central Division 4: West North Central Region 3: South Division 5: South Atlantic Division 6: East South Central Division 7: West South Central Region 4: West Division 8: Mountain Division 9: Pacific Many federal, state and tribal governments use census data to: Decide the location of new housing and public facilities, Examine the demographic characteristics of communities and the US, Plan transportation systems and roadways, Determine quotas and creation of police and fire precincts, Create localized areas for elections, utilities, etc.
Gathers population information every 10 years The United States Census Bureau is committed to confidentiality, guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U. S. Code establishes penalties for the disclosure of this information. All Census employees must sign an affidavit of non-disclosure prior to employment; the Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; 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; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

The term fish processing refers to the processes associated with fish and fish products between the time fish are caught or harvested, the time the final product is delivered to the customer. Although the term refers to fish, in practice it is extended to cover any aquatic organisms harvested for commercial purposes, whether caught in wild fisheries or harvested from aquaculture or fish farming. Larger fish processing companies operate their own fishing fleets or farming operations; the products of the fish industry are sold to grocery chains or to intermediaries. Fish are perishable. A central concern of fish processing is to prevent fish from deteriorating, this remains an underlying concern during other processing operations. Fish processing can be subdivided into fish handling, the preliminary processing of raw fish, the manufacture of fish products. Another natural subdivision is into primary processing involved in the filleting and freezing of fresh fish for onward distribution to fresh fish retail and catering outlets, the secondary processing that produces chilled and canned products for the retail and catering trades.
There is evidence humans. These days, fish processing is undertaken by artisan fishermen, on board fishing or fish processing vessels, at fish processing plants. Fish is a perishable food which needs proper handling and preservation if it is to have a long shelf life and retain a desirable quality and nutritional value; the central concern of fish processing is to prevent fish from deteriorating. The most obvious method for preserving the quality of fish is to keep them alive until they are ready for cooking and eating. For thousands of years, China achieved this through the aquaculture of carp. Other methods used to preserve fish and fish products include the control of temperature using ice, refrigeration or freezing the control of water activity by drying, smoking or freeze-drying the physical control of microbial loads through microwave heating or ionizing irradiation the chemical control of microbial loads by adding acids oxygen deprivation, such as vacuum packing. More than one of these methods is used.
When chilled or frozen fish or fish products are transported by road, sea or air, the cold chain must be maintained. This requires adequate refrigeration. Modern shipping containers can combine refrigeration with a controlled atmosphere. Fish processing is concerned with proper waste management and with adding value to fish products. There is an increasing demand for ready to eat fish products, or products that do not need much preparation; when fish are captured or harvested for commercial purposes, they need some preprocessing so they can be delivered to the next part of the marketing chain in a fresh and undamaged condition. This means, for example, that fish caught by a fishing vessel need handling so they can be stored safely until the boat lands the fish on shore. Typical handling processes are transferring the catch from the fishing gear to the fishing vessel holding the catch before further handling sorting and grading bleeding and washing chilling storing the chilled fish unloading, or landing the fish when the fishing vessel returns to portThe number and order in which these operations are undertaken varies with the fish species and the type of fishing gear used to catch it, as well as how large the fishing vessel is and how long it is at sea, the nature of the market it is supplying.
Catch processing operations can be automated. The equipment and procedures in modern industrial fisheries are designed to reduce the rough handling of fish, heavy manual lifting and unsuitable working positions which might result in injuries. An alternative, obvious way of keeping fish fresh is to keep them alive until they are delivered to the buyer or ready to be eaten; this is a common practice worldwide. The fish are placed in a container with clean water, dead, damaged or sick fish are removed; the water temperature is lowered and the fish are starved to reduce their metabolic rate. This decreases fouling of water with metabolic products that become toxic and make it difficult for the fish to extract oxygen. Fish can be kept alive in floating cages and fish ponds. In aquaculture, holding basins are used where the water is continuously filtered and its temperature and oxygen level are controlled. In China, floating cages are constructed in rivers out of palm woven baskets, while in South America simple fish yards are built in the backwaters of rivers.
Live fish can be transported by methods which range from simple artisanal methods where fish are placed in plastic bags with an oxygenated atmosphere, to sophisticated systems which use trucks that filter and recycle the water, add oxygen and regulate temperature. Preservation techniques are needed to lengthen shelf life, they are designed to inhibit the activity of spoilage bacteria and the metabolic changes that result in the loss of fish quality. Spoilage bacteria are the specific bacteria that produce the unpleasant odours and flavours associated with spoiled fish. Fish host many bacteria that are not spoilage bacteria, most of the bacteria present on spoiled fish played no role in the spoilage. To flourish, bacteria need the right temperature, sufficient water and oxygen, surroundings that are not too acidic. Preservation techniques work by interrupting one or more of these needs. Preservation techniques can be classified. If the temperature is decreased, the metabolic activity in the fish from microbial or autolytic processes can b
The Aleuts, who are known in the Aleut language by the endonyms Unangan, Unangas, Унаңан, are the indigenous people of the Aleutian Islands. Both the Aleut people and the islands are divided between the U. S. state of Alaska and the Russian administrative division of Kamchatka Krai. Aleut people speak Unangam, the Aleut language, as well as English and Russian in the United States and Russia respectively. An estimated 150 people in the United States and five people in Russia speak Aleut; the language belongs to the Eskimo-Aleut language family and includes three dialects: Eastern Aleut, spoken on the Eastern Aleutian, Shumagin and Pribilof Islands. The Pribilof Islands boast the highest number of active speakers of Aleutian. Most of the Native elders speak Aleut, but it is rare for an everyday person to speak the language fluently. Beginning in 1829, Aleut was written in the Cyrillic script. From 1870, the language has been written in the Latin script. An Aleut dictionary and grammar have been published, portions of the Bible were translated into Aleut.
The Aleut dialects and tribes: Attuan dialect and speaking tribes: Sasignan / Sasxinan / Sasxinas or Near Islanders: in the Near Islands. Kasakam Unangangis or Copper Island Aleut: in the Commander Islands of Russian Federation.? Qax̂un or Rat Islanders: in the Buldir Island and Rat Islands. Atkan dialect or Western Aleut or Aliguutax̂ and speaking tribes: Naahmiĝus or Delarof Islanders: in the Delarof Islands and Andreanof Islands. Niiĝuĝis or Andreanof Islanders: in the Andreanof Islands. Eastern Aleut dialect and speaking tribes: Akuuĝun or Uniiĝun or Islanders of the Four Mountains: in the Islands of Four Mountains. Qawalangin or Fox Islanders: in the Fox Islands. Qigiiĝun or Krenitzen Islanders: in the Krenitzin Islands. Qagaan Tayaĝungin or Sanak Islanders: in the Sanak Islands. Taxtamam Tunuu dialect of Belkofski. Qaĝiiĝun or Shumigan Islanders: in the Shumagin Islands; the Aleut people lived throughout the Aleutian Islands, the Shumagin Islands, the far western part of the Alaska Peninsula, with an estimated population of around 25,000 prior to European contact.
In the 1820s, the Russian-American Company administered a large portion of the North Pacific during a Russian-led expansion of the fur trade. They resettled many Aleut families to the Pribilof Islands; these continue to have majority-Aleut communities. According to the 2000 Census, 11,941 people identified as being Aleut, while 17,000 identified as having partial Aleut ancestry. Prior to sustained European contact 25,000 Aleut lived in the archipelago; the Encyclopædia Britannica Online says more than 15,000 people have Aleut ancestry in the early 21st century. The Aleut suffered high fatalities in the 19th and early 20th centuries from Eurasian infectious diseases to which they had no immunity. In addition, the population suffered. Russian traders and Europeans married Aleut women and had families with them. After the arrival of Russian Orthodox missionaries in the late 18th century, many Aleuts became Christian. Of the numerous Russian Orthodox congregations in Alaska, most are majority Alaska Native in ethnicity.
One of the earliest Christian martyrs in North America was Saint Peter the Aleut. ` In the 18th century, Russia promyshlenniki traders established settlements on the islands. There was high demand for the furs. In May 1784, local Aleuts revolted on Amchitka against the Russian traders. According to what Aleut people said, in an account recorded by Japanese castaways and published in 2004, otters were decreasing year by year; the Russians paid the Aleuts less in goods in return for the furs they made. The Japanese learned; the leading Aleuts negotiated with the Russians, saying they had failed to deliver enough supplies in return for furs. Nezimov, leader of the Russians, ordered two of his men and Kazhimov to kill his mistress Oniishin, the Aleut chief's daughter, because he doubted that Oniishin had tried to dissuade her father and other leaders from pushing for more goods; that evening, hundreds of Aleut men marched to the Russians' houses. When five Russians opened fire, the Aleuts ran away; the next day the Aleut escaped again when the Russians started firing.
While the men attempted another attack the next day, they yelled and moved more towards the house. As Russians opened fire, they started to run away again. After they ran, the Russians noticed; the Russians took around children hostage, forcing the Aleuts to surrender. The Russians killed four Aleut leaders. After the four leaders had been killed, the Aleuts began to move from Amchitka to neighboring islands. Nezimov, leader of the Russian group, was jailed after the whole incident was reported to Russian officials. In 1811, in
An oceanic climate known as a marine climate or maritime climate, is the Köppen classification of climate typical of west coasts in higher middle latitudes of continents, features mild summers and mild winters, with a narrow annual temperature range and few extremes of temperature, with the exception for transitional areas to continental and highland climates. Oceanic climates are defined as having a monthly mean temperature below 22 °C in the warmest month, above 0 °C in the coldest month, it lacks a dry season, as precipitation is more evenly dispersed throughout the year. It is the predominant climate type across much of Western Europe including the United Kingdom, the Pacific Northwest region of the United States and Canada, portions of central Mexico, southwestern South America, southeastern Australia including Tasmania, New Zealand, as well as isolated locations elsewhere. Oceanic climates are characterised by a narrower annual range of temperatures than in other places at a comparable latitude, do not have the dry summers of Mediterranean climates or the hot summers of humid subtropical.
Oceanic climates are most dominant in Europe, where they spread much farther inland than in other continents. Oceanic climates can have considerable storm activity as they are located in the belt of the stormy westerlies. Many oceanic climates have frequent cloudy or overcast conditions due to the near constant storms and lows tracking over or near them; the annual range of temperatures is smaller than typical climates at these latitudes due to the constant stable marine air masses that pass through oceanic climates, which lack both warm and cool fronts. Locations with oceanic climates tend to feature cloudy conditions with precipitation, though it can experience clear, sunny days. London is an example of an oceanic climate, it experiences constant precipitation throughout the entire year. Despite this, thunderstorms are quite rare since hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year.
However, some areas with this climate see some snowfall annually during winter. Most oceanic climate zones, or at least a part of them, experience at least one snowfall per year. In the poleward locations of the oceanic climate zone, snowfall is more commonplace. Overall temperature characteristics of the oceanic climates feature cool temperatures and infrequent extremes of temperature. In the Köppen climate classification, Oceanic climates have a mean temperature of 0 °C or higher in the coldest month, compared to continental climates where the coldest month has a mean temperature of below 0 °C. Summers are cool, with the warmest month having a mean temperature below 22 °C. Poleward of the latter is a zone of the aforementioned subpolar oceanic climate, with long but mild winters and cool and short summers. Examples of this climate include parts of coastal Iceland, Norway, the Scottish Highlands, the mountains of Vancouver Island, Haida Gwaii in Canada, in the Northern Hemisphere and extreme southern Chile and Argentina in the Southern Hemisphere, the Tasmanian Central Highlands, parts of New Zealand.
Oceanic climates are not always found in coastal locations on the aforementioned parallels. The polar jet stream, which moves in a west to east direction across the middle latitudes, advances low pressure systems and fronts. In coastal areas of the higher middle latitudes, the prevailing onshore flow creates the basic structure of most oceanic climates. Oceanic climates are a reflection of the ocean adjacent to them. In the fall and early spring, when the polar jet stream is most active, the frequent passing of marine weather systems creates the frequent fog, cloudy skies, light drizzle associated with oceanic climates. In summer, high pressure pushes the prevailing westerlies north of many oceanic climates creating a drier summer climate; the North Atlantic Gulf Stream, a tropical oceanic current that passes north of the Caribbean and up the East Coast of the United States to North Carolina heads east-northeast to the Azores, is thought to modify the climate of Northwest Europe. As a result of the Gulf Stream, west-coast areas located in high latitudes like Ireland, the UK, Norway have much milder winters than would otherwise be the case.
The lowland attributes of western Europe help drive marine air masses into continental areas, enabling cities such as Dresden and Vienna to have maritime climates in spite of being located well inland from the ocean. Oceanic climates in Europe occur in Northwest Europe, from Ireland and Great Britain eastward to central Europe. Most of France, the Netherlands, Germany, the north coast of Spain, the western Azores off the coast of Portugal, the south of Kosovo and southern portions of Sweden have oceanic climates. Examples of oceanic climates are found in Glasgow, Bergen, Dublin, Bilbao, Donostia-San Sebastian, Bayonne, Züri
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.
