South Dakota is a U. S. state in the Midwestern region of the United States. It is named after the Lakota and Dakota Sioux Native American tribes, who compose a large portion of the population and dominated the territory. South Dakota is the seventeenth largest by area, but the fifth smallest by population and the 5th least densely populated of the 50 United States; as the southern part of the former Dakota Territory, South Dakota became a state on November 2, 1889 with North Dakota. Pierre is the state capital and Sioux Falls, with a population of about 187,200, is South Dakota's largest city. South Dakota is bordered by the states of North Dakota, Iowa, Nebraska and Montana; the state is bisected by the Missouri River, dividing South Dakota into two geographically and distinct halves, known to residents as "East River" and "West River". Eastern South Dakota is home to most of the state's population, the area's fertile soil is used to grow a variety of crops. West of the Missouri, ranching is the predominant agricultural activity, the economy is more dependent on tourism and defense spending.
Most of the Native American reservations are in West River. The Black Hills, a group of low pine-covered mountains sacred to the Sioux, are in the southwest part of the state. Mount Rushmore, a major tourist destination, is there. South Dakota has a temperate continental climate, with four distinct seasons and precipitation ranging from moderate in the east to semi-arid in the west; the state's ecology features species typical of a North American grassland biome. Humans have inhabited the area for several millennia, with the Sioux becoming dominant by the early 19th century. In the late 19th century, European-American settlement intensified after a gold rush in the Black Hills and the construction of railroads from the east. Encroaching miners and settlers triggered a number of Indian wars, ending with the Wounded Knee Massacre in 1890. Key events in the 20th century included the Dust Bowl and Great Depression, increased federal spending during the 1940s and 1950s for agriculture and defense, an industrialization of agriculture that has reduced family farming.
While several Democratic senators have represented South Dakota for multiple terms at the federal level, the state government is controlled by the Republican Party, whose nominees have carried South Dakota in each of the last 13 presidential elections. Dominated by an agricultural economy and a rural lifestyle, South Dakota has sought to diversify its economy in areas to attract and retain residents. South Dakota's history and rural character still influence the state's culture. South Dakota is in the north-central United States, is considered a part of the Midwest by the U. S. Census Bureau; the culture and geography of western South Dakota have more in common with the West than the Midwest. South Dakota has a total area of 77,116 square miles, making the state the 17th largest in the Union. Black Elk Peak named Harney Peak, with an elevation of 7,242 ft, is the state's highest point, while the shoreline of Big Stone Lake is the lowest, with an elevation of 966 ft. South Dakota is bordered to the north by North Dakota.
The geographical center of the U. S. is 17 miles west of Castle Rock in Butte County. The North American continental pole of inaccessibility is between Allen and Kyle, 1,024 mi from the nearest coastline; the Missouri River is the longest river in the state. Other major South Dakota rivers include the Cheyenne, Big Sioux, White Rivers. Eastern South Dakota has many natural lakes created by periods of glaciation. Additionally, dams on the Missouri River create four large reservoirs: Lake Oahe, Lake Sharpe, Lake Francis Case, Lewis and Clark Lake. South Dakota can be divided into three regions: eastern South Dakota, western South Dakota, the Black Hills; the Missouri River serves as a boundary in terms of geographic and political differences between eastern and western South Dakota. The geography of the Black Hills, long considered sacred by Native Americans, differs from its surroundings to such an extent it can be considered separate from the rest of western South Dakota. At times the Black Hills are combined with the rest of western South Dakota, people refer to the resulting two regions divided by the Missouri River as West River and East River.
Eastern South Dakota features higher precipitation and lower topography than the western part of the state. Smaller geographic regions of this area include the Coteau des Prairies, the Dissected Till Plains, the James River Valley; the Coteau des Prairies is a plateau bordered on the east by the Minnesota River Valley and on the west by the James River Basin. Further west, the James River Basin is low, flat eroded land, following the flow of the James River through South Dakota from north to south; the Dissected Till Plains, an area of rolling hills and fertile soil that covers much of Iowa and Nebraska, extends into the southeastern corner of South Dakota. Layers deposited during the Pleistocene epoch, starting around two million years ago, cover most of eastern South Dakota; these are the youngest rock and sediment layers in the state, the product of several successive periods of glaciation which deposited a large amount of rocks and soil, known as till, over the area. The Great Plains cover most of the western two-thirds of South Dakota.

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.

Per capita income
Per capita income or average income measures the average income earned per person in a given area in a specified year. It is calculated by dividing the area's total income by its total population. Per capita income is national income divided by population size. Per capita income is used to measure an area's average income and compare the wealth of different populations. Per capita income is used to measure a country's standard of living, it is expressed in terms of a used international currency such as the euro or United States dollar, is useful because it is known, is calculable from available gross domestic product and population estimates, produces a useful statistic for comparison of wealth between sovereign territories. This helps to ascertain a country's development status, it is one of the three measures for calculating the Human Development Index of a country. In the United States, it is defined by the U. S. Census Bureau as the following: "Per capita income is the mean money income received in the past 12 months computed for every man and child in a geographic area."
Critics claim that per capita income has several weaknesses in measuring prosperity: Comparisons of per capita income over time need to consider inflation. Without adjusting for inflation, figures tend to overstate the effects of economic growth. International comparisons can be distorted by cost of living differences not reflected in exchange rates. Where the objective is to compare living standards between countries, adjusting for differences in purchasing power parity will more reflect what people are able to buy with their money, it does not reflect income distribution. If a country's income distribution is skewed, a small wealthy class can increase per capita income while the majority of the population has no change in income. In this respect, median income is more useful when measuring of prosperity than per capita income, as it is less influenced by outliers. Non-monetary activity, such as barter or services provided within the family, is not counted; the importance of these services varies among economies.
Per capita income does not consider whether income is invested in factors to improve the area's development, such as health, education, or infrastructure.

A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

Nebraska is a state that lies in both the Great Plains and the Midwestern United States. It is bordered by South Dakota to the north, it is the only triply landlocked U. S. state. Nebraska's area is just over 77,220 square miles with a population of 1.9 million people. Its state capital is Lincoln, its largest city is Omaha, on the Missouri River. Indigenous peoples, including Omaha, Ponca, Pawnee and various branches of the Lakota tribes, lived in the region for thousands of years before European exploration; the state is crossed including that of the Lewis and Clark Expedition. Nebraska was admitted as the 37th state of the United States in 1867, it is the only state in the United States whose legislature is unicameral and nonpartisan. Nebraska is composed of two major land regions: the Great Plains; the Dissected Till Plains region consist of rolling hills and contains the state's largest cities and Lincoln. The Great Plains region, occupying most of western Nebraska, is characterized by treeless prairie, suitable for cattle-grazing.
Nebraska has two major climatic zones. The eastern half of the state has a humid continental climate; the western half of the state has a semi-arid climate. The state has wide variations between winter and summer temperatures, variations that decrease moving south in the state. Violent thunderstorms and tornadoes occur during spring and summer and sometimes in autumn. Chinook winds tend to warm the state in the winter and early spring. Nebraska's name is derived from transliteration of the archaic Otoe words Ñí Brásge, pronounced, or the Omaha Ní Btháska, meaning "flat water", after the Platte River that flows through the state. Indigenous peoples lived in the region of present-day Nebraska for thousands of years before European exploration; the historic tribes in the state included the Omaha, Ponca, Pawnee and various branches of the Lakota, some of which migrated from eastern areas into this region. When European exploration and settlement began, both Spain and France sought to control the region.
In the 1690s, Spain established trade connections with the Apaches, whose territory included western Nebraska. By 1703, France had developed a regular trade with the native peoples along the Missouri River in Nebraska, by 1719 had signed treaties with several of these peoples. After war broke out between the two countries, Spain dispatched an armed expedition to Nebraska under Lieutenant General Pedro de Villasur in 1720; the party was attacked and destroyed near present-day Columbus by a large force of Pawnees and Otoes, both allied to the French. The massacre ended Spanish exploration of the area for the remainder of the 18th century. In 1762, during the Seven Years' War, France ceded the Louisiana territory to Spain; this left Spain competing for dominance along the Mississippi. In response, Spain dispatched two trading expeditions up the Missouri in 1794 and 1795; that year, Mackay's party built a trading post, dubbed Fort Carlos IV, near present-day Homer. In 1819, the United States established Fort Atkinson as the first U.
S. Army post west of the Missouri River, just east of present-day Fort Calhoun; the army abandoned the fort in 1827. European-American settlement was scarce until the California Gold Rush. On May 30, 1854, the US Congress created the Kansas and the Nebraska territories, divided by the Parallel 40° North, under the Kansas–Nebraska Act; the Nebraska Territory included parts of the current states of Colorado, North Dakota, South Dakota and Montana. The territorial capital of Nebraska was Omaha. In the 1860s, after the U. S. government forced many of the Native American tribes to cede their lands and settle on reservations, it opened large tracts of land to agricultural development by Europeans and Americans. Under the Homestead Act, thousands of settlers migrated into Nebraska to claim free land granted by the federal government; because so few trees grew on the prairies, many of the first farming settlers built their homes of sod, as had Native Americans such as the Omaha. The first wave of settlement gave the territory a sufficient population to apply for statehood.
Nebraska became the 37th state on March 1, 1867, the capital was moved from Omaha to the center at Lancaster renamed Lincoln after the assassinated President of the United States, Abraham Lincoln. The battle of Massacre Canyon on August 5, 1873, was the last major battle between the Pawnee and the Sioux. During the 1870s to the 1880s, Nebraska experienced a large growth in population. Several factors contributed to attracting new residents; the first was. This helped settlers to learn the unfamiliar geography of the area; the second factor was the invention of several farming technologies. Agricultural inventions such as barbed wire, wind mills, the steel plow, combined with good weather, enabled settlers to use of Nebraska as prime farming land. By the 1880s, Nebraska's population
