Mississippi is a state located in the southeastern region of the United States. Mississippi is the 32nd most 34th most populous of the 50 United States, it is bordered by Tennessee to the north, Alabama to the east, the Gulf of Mexico and Louisiana to the south, Arkansas and Louisiana to the west. The state's western boundary is defined by the Mississippi River. Jackson, with a population of 167,000 people, is both the state's capital and largest city; the state is forested outside the Mississippi Delta area, the area between the Mississippi and Yazoo rivers. Before the American Civil War, most development in the state was along riverfronts, as the waterways were critical for transportation. Large gangs of slaves were used to work on cotton plantations. After the war, freedmen began to clear the bottomlands to the interior, in the process selling off timber and buying property. By the end of the 19th century, African Americans made up two-thirds of the Delta's property owners, but timber and railroad companies acquired much of the land after the financial crisis, which occurred when blacks were facing increasing racial discrimination and disfranchisement in the state.
Clearing of the land for plantations altered the Delta's ecology, increasing the severity of flooding along the Mississippi by taking out trees and bushes that had absorbed excess waters. Much land is now held by agribusinesses. A rural state with agricultural areas dominated by industrial farms, Mississippi is ranked low or last among the states in such measures as health, educational attainment, median household income; the state's catfish aquaculture farms produce the majority of farm-raised catfish consumed in the United States. Since the 1930s and the Great Migration of African Americans to the North and West, the majority of Mississippi's population has been white, although the state still has the highest percentage of black residents of any U. S. state. From the early 19th century to the 1930s, its residents were majority black, before the American Civil War that population was composed of African-American slaves. Democratic Party whites retained political power through disfranchisement and Jim Crow laws.
In the first half of the 20th century, nearly 400,000 rural blacks left the state for work and opportunities in northern and midwestern cities, with another wave of migration around World War II to West Coast cities. In the early 1960s, Mississippi was the poorest state in the nation, with 86% of its non-whites living below the poverty level. In 2010, 37% of Mississippians were African Americans, the highest percentage of African Americans in any U. S. state. Since regaining enforcement of their voting rights in the late 1960s, most African Americans have supported Democratic candidates in local and national elections. Conservative whites have shifted to the Republican Party. African Americans are a majority in many counties of the Mississippi-Yazoo Delta, an area of historic slave settlement during the plantation era; the state's name is derived from the Mississippi River. Settlers named it after the Ojibwe word misi-ziibi. Mississippi is bordered to the north by Tennessee, to the east by Alabama, to the south by Louisiana and a narrow coast on the Gulf of Mexico.
In addition to its namesake, major rivers in Mississippi include the Big Black River, the Pearl River, the Yazoo River, the Pascagoula River, the Tombigbee River. Major lakes include Ross Barnett Reservoir, Arkabutla Lake, Sardis Lake, Grenada Lake with the largest lake being Sardis Lake. Mississippi is composed of lowlands, the highest point being Woodall Mountain, in the foothills of the Cumberland Mountains, 807 feet above sea level; the lowest point is sea level at the Gulf Coast. The state's mean elevation is 300 feet above sea level. Most of Mississippi is part of the East Gulf Coastal Plain; the coastal plain is composed of low hills, such as the Pine Hills in the south and the North Central Hills. The Pontotoc Ridge and the Fall Line Hills in the northeast have somewhat higher elevations. Yellow-brown loess soil is found in the western parts of the state; the northeast is a region of fertile black earth. The coastline includes large bays at Bay St. Louis and Pascagoula, it is separated from the Gulf of Mexico proper by the shallow Mississippi Sound, sheltered by Petit Bois Island, Horn Island and West Ship Islands, Deer Island, Round Island, Cat Island.
The northwest remainder of the state consists of the Mississippi Delta, a section of the Mississippi Alluvial Plain. The plain widens north of Vicksburg; the region has rich soil made up of silt, deposited by the flood waters of the Mississippi River. Areas under the management of the National Park Service include: Brices Cross Roads National Battlefield Site near Baldwyn Gulf Islands National Seashore Natchez National Historical Park in Natchez Natchez Trace National Scenic Trail in Tupelo Natchez Trace Parkway Tupelo National Battlefield in Tupelo Vicksburg National Military Park and Cemetery in Vicksburg Mississippi City Population Rankings of at least 50,000: Mississippi City Population Rankings of at least 20,000 but fewer than 50,000: Mississippi City Population Rankings of at least 10,000 but fewer than 20,000: Mississippi has a humid
African Americans are an ethnic group of Americans with total or partial ancestry from any of the black racial groups of Africa. The term refers to descendants of enslaved black people who are from the United States. Black and African Americans constitute the third largest racial and ethnic group in the United States. Most African Americans are descendants of enslaved peoples within the boundaries of the present United States. On average, African Americans are of West/Central African and European descent, some have Native American ancestry. According to U. S. Census Bureau data, African immigrants do not self-identify as African American; the overwhelming majority of African immigrants identify instead with their own respective ethnicities. Immigrants from some Caribbean, Central American and South American nations and their descendants may or may not self-identify with the term. African-American history starts in the 16th century, with peoples from West Africa forcibly taken as slaves to Spanish America, in the 17th century with West African slaves taken to English colonies in North America.
After the founding of the United States, black people continued to be enslaved, the last four million black slaves were only liberated after the Civil War in 1865. Due to notions of white supremacy, they were treated as second-class citizens; the Naturalization Act of 1790 limited U. S. citizenship to whites only, only white men of property could vote. These circumstances were changed by Reconstruction, development of the black community, participation in the great military conflicts of the United States, the elimination of racial segregation, the civil rights movement which sought political and social freedom. In 2008, Barack Obama became the first African American to be elected President of the United States; the first African slaves arrived via Santo Domingo to the San Miguel de Gualdape colony, founded by Spanish explorer Lucas Vázquez de Ayllón in 1526. The marriage between Luisa de Abrego, a free black domestic servant from Seville and Miguel Rodríguez, a white Segovian conquistador in 1565 in St. Augustine, is the first known and recorded Christian marriage anywhere in what is now the continental United States.
The ill-fated colony was immediately disrupted by a fight over leadership, during which the slaves revolted and fled the colony to seek refuge among local Native Americans. De Ayllón and many of the colonists died shortly afterwards of an epidemic and the colony was abandoned; the settlers and the slaves who had not escaped returned to Haiti, whence. The first recorded Africans in British North America were "20 and odd negroes" who came to Jamestown, Virginia via Cape Comfort in August 1619 as indentured servants; as English settlers died from harsh conditions and more Africans were brought to work as laborers. An indentured servant would work for several years without wages; the status of indentured servants in early Virginia and Maryland was similar to slavery. Servants could be bought, sold, or leased and they could be physically beaten for disobedience or running away. Unlike slaves, they were freed after their term of service expired or was bought out, their children did not inherit their status, on their release from contract they received "a year's provision of corn, double apparel, tools necessary", a small cash payment called "freedom dues".
Africans could raise crops and cattle to purchase their freedom. They raised families, married other Africans and sometimes intermarried with Native Americans or English settlers. By the 1640s and 1650s, several African families owned farms around Jamestown and some became wealthy by colonial standards and purchased indentured servants of their own. In 1640, the Virginia General Court recorded the earliest documentation of lifetime slavery when they sentenced John Punch, a Negro, to lifetime servitude under his master Hugh Gwyn for running away. In the Spanish Florida some Spanish married or had unions with Pensacola, Creek or African women, both slave and free, their descendants created a mixed-race population of mestizos and mulattos; the Spanish encouraged slaves from the southern British colonies to come to Florida as a refuge, promising freedom in exchange for conversion to Catholicism. King Charles II of Spain issued a royal proclamation freeing all slaves who fled to Spanish Florida and accepted conversion and baptism.
Most went to the area around St. Augustine, but escaped slaves reached Pensacola. St. Augustine had mustered an all-black militia unit defending Spain as early as 1683. One of the Dutch African arrivals, Anthony Johnson, would own one of the first black "slaves", John Casor, resulting from the court ruling of a civil case; the popular conception of a race-based slave system did not develop until the 18th century. The Dutch West India Company introduced slavery in 1625 with the importation of eleven black slaves into New Amsterdam. All the colony's slaves, were freed upon its surrender to the British. Massachusetts was the first British colony to recognize slavery in 1641. In 1662, Virginia passed a law that children of enslaved women took the status of the mother, rather than that of the father, as under English common law; this principle was called partus sequitur ventrum. By an act of 1699, the colony ordered all free blacks deported defining as slaves all people of African descent who remained in the c
The Loop, one of Chicago's 77 designated community areas, is the central business district in the downtown area of the city. It is home to Chicago's commercial core, City Hall, the seat of Cook County. Bounded on the north and west by the Chicago River, on the east by Lake Michigan, on the south by Roosevelt Road, it is the second largest commercial business district in the United States after Midtown Manhattan and contains the headquarters of many locally and globally important businesses as well as many of Chicago's most famous attractions. In what is now the Loop, on the south bank of the Chicago River near today's Michigan Avenue Bridge, the United States Army erected Fort Dearborn in 1803, the first settlement in the area sponsored by the United States. In the late nineteenth century cable car turnarounds and a prominent elevated railway encircled the area, giving the Loop its name. Around the same time some of the world's earliest skyscrapers were constructed in the area. In 1908, Chicago addresses were made uniform by naming the intersection of State Street and Madison Street in the Loop as the origin of the Chicago street grid.
Some believe the origin of the term Loop is derived from the cable car, those of two lines that shared a loop, constructed in 1882, bounded by Van Buren, Wabash and Lake. Other research has concluded that "the Loop" was not used as a proper noun until after the 1895–97 construction of the Union elevated railway loop. Fort Dearborn was established in the first American-backed settlement in the area; when Chicago was platted in 1830, it included what is now the Loop north of Madison Street and west of State Street. Except for the Fort Dearborn reservation and land reclaimed from Lake Michigan, the entirety of what is now the Loop was part of the Town of Chicago when it was incorporated in 1833 and the area was bustling by the end of the 1830s. Passenger lines reached seven Loop-area stations by the 1890s, with transfers from one to the other being a major business for taxi drivers prior to the advent of Amtrak in the 1970s and the majority of trains being concentrated at Chicago Union Station.
The construction of a streetcar loop in 1882 and the elevated railway loop in the 1890s gave the area its name and cemented its dominance in the city. Afterwards, suburbanization caused a decrease in the area's importance. Starting in the 1960s, the presence of an upscale shopping district caused the area's fortunes to increase; the area has long been a hub for architecture. The vast majority of the area was rebuilt quickly. In 1885 the Home Insurance Building considered the world's first skyscraper, was constructed, followed by the development of the Chicago school best exemplified by such buildings as the Rookery Building in 1888, the Monadnock Building in 1891, the Sullivan Center in 1899. From the 1890s to the 1940s, local aldermen "Bathhouse John" Coughlin and Michael "Hinky Dink" Kenna led the so-called "Gray Wolves" of Chicago, a notoriously corrupt group of aldermen, they hosted the First Ward Ball in the area at the Chicago Coliseum, an event that brought together various people of ill repute and by the time of its forced closure in 1909 raised over $50,000 a year for the aldermen.
Coughlin served from 1892 until his death in 1938. He was from the area and owned several bathhouses in it, although in his years he lived in the nearby Near South Side. Kenna served as alderman from 1897 to 1923, when he stepped down in favor of Coughlin when the number of aldermen per ward decreased from two to one, again from 1939 to 1943 upon Coughlin's death. Corruption in the area would continue throughout the 20th century. Subsequent aldermen John D'Arco Sr. and Fred Roti were accused of being fronts for the mob, the 1st ward was moved in 1992 from the Loop up north to its current position in West Town in an effort to stymie corruption, the Loop itself being dispersed across several wards. Loop architecture has been dominated by high-rises since early in its history. Notable buildings include the Home Insurance Building, considered the world's first skyscraper; some of the historic buildings in this district were instrumental in the development of towers. Chicago's street numbering system – dividing addresses into North, South and West quadrants originates in the Loop at the intersection of State Street and Madison Street.
This area abounds in shopping opportunities, including the Loop Retail Historic District, although it competes with the more upscale Magnificent Mile area to the north. It includes Chicago's former Marshall Field's department store location in the Marshall Field and Company Building. Chicago's Downtown Theatre District is found within this area, along with numerous restaurants and hotels. Chicago has a famous skyline which features many of the tallest buildings in the world as well as the Chicago Landmark Historic Michigan Boulevard District. Chicago's skyline is spaced out throughout the downtown area; the Willis Tower known as the Sears Tower, the second tallest building in the Western Hemisphere, stands in the western Loop in the heart of the city's f

Tennessee is a state located in the southeastern region of the United States. Tennessee is the 16th most populous of the 50 United States. Tennessee is bordered by Kentucky to the north, Virginia to the northeast, North Carolina to the east, Georgia and Mississippi to the south, Arkansas to the west, Missouri to the northwest; the Appalachian Mountains dominate the eastern part of the state, the Mississippi River forms the state's western border. Nashville is the state's capital and largest city, with a 2017 population of 667,560. Tennessee's second largest city is Memphis, which had a population of 652,236 in 2017; the state of Tennessee is rooted in the Watauga Association, a 1772 frontier pact regarded as the first constitutional government west of the Appalachians. What is now Tennessee was part of North Carolina, part of the Southwest Territory. Tennessee was admitted to the Union as the 16th state on June 1, 1796. Tennessee was the last state to leave the Union and join the Confederacy at the outbreak of the American Civil War in 1861.
Occupied by Union forces from 1862, it was the first state to be readmitted to the Union at the end of the war. Tennessee furnished more soldiers for the Confederate Army than any other state besides Virginia, more soldiers for the Union Army than the rest of the Confederacy combined. Beginning during Reconstruction, it had competitive party politics, but a Democratic takeover in the late 1880s resulted in passage of disenfranchisement laws that excluded most blacks and many poor whites from voting; this reduced competition in politics in the state until after passage of civil rights legislation in the mid-20th century. In the 20th century, Tennessee transitioned from an agrarian economy to a more diversified economy, aided by massive federal investment in the Tennessee Valley Authority and, in the early 1940s, the city of Oak Ridge; this city was established to house the Manhattan Project's uranium enrichment facilities, helping to build the world's first atomic bombs, two of which were dropped on Imperial Japan near the end of World War II.
Tennessee's major industries include agriculture and tourism. Poultry and cattle are the state's primary agricultural products, major manufacturing exports include chemicals, transportation equipment, electrical equipment; the Great Smoky Mountains National Park, the nation's most visited national park, is headquartered in the eastern part of the state, a section of the Appalachian Trail follows the Tennessee-North Carolina border. Other major tourist attractions include the Tennessee Aquarium in Chattanooga; the earliest variant of the name that became Tennessee was recorded by Captain Juan Pardo, the Spanish explorer, when he and his men passed through an American Indian village named "Tanasqui" in 1567 while traveling inland from South Carolina. In the early 18th century, British traders encountered a Cherokee town named Tanasi in present-day Monroe County, Tennessee; the town was located on a river of the same name, appears on maps as early as 1725. It is not known whether this was the same town as the one encountered by Juan Pardo, although recent research suggests that Pardo's "Tanasqui" was located at the confluence of the Pigeon River and the French Broad River, near modern Newport.
The meaning and origin of the word are uncertain. Some accounts suggest, it has been said to mean "meeting place", "winding river", or "river of the great bend". According to ethnographer James Mooney, the name "can not be analyzed" and its meaning is lost; the modern spelling, Tennessee, is attributed to James Glen, the governor of South Carolina, who used this spelling in his official correspondence during the 1750s. The spelling was popularized by the publication of Henry Timberlake's "Draught of the Cherokee Country" in 1765. In 1788, North Carolina created "Tennessee County", the third county to be established in what is now Middle Tennessee; when a constitutional convention met in 1796 to organize a new state out of the Southwest Territory, it adopted "Tennessee" as the name of the state. Tennessee is known as The Volunteer State, a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee during the Battle of New Orleans.
Other sources differ on the origin of the state nickname. This explanation is more because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican–American War resulted in 30,000 volunteers from Tennessee alone in response to the death of Davy Crockett and appeals by former Tennessee Governor and Texas politician, Sam Houston. Tennessee borders eight other states: Virginia to the north. Tennessee is tied with Missouri as the state bordering the most other states; the state is trisected by the Tennessee River. The highest point in the state is Clingmans Dome at 6,643 feet (
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.

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.
