1990 United States Census
Approximately 16 percent of households received a long form of the 1990 census, which contained over 100 questions. Full documentation on the 1990 census, including forms and a procedural history, is available from the Integrated Public Use Microdata Series. It was the first census to designate Native Hawaiian and Other Pacific Islander as a group separate from Asians. To increase black participation in the 1990 United States Census, the bureau recruited Bill Cosby, Magic Johnson, Alfre Woodard, the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, personally identifiable information will be available in 2062. The results of the 1990 census determined the number of seats that each state receives in the United States House of Representatives starting with the 1992 elections, this affected the number of votes each state has in the Electoral College for the 1992 presidential election. Because of population changes, twenty-one states had changes in their number of seats, eight states gained at least one seat, and thirteen states lost at least one seat.
The final result involved 19 seats being switched
Las Vegas Valley (landform)
Las Vegas Valley is a basin located in the U. S. state of Nevada. The valley in the northwest section is a northwest-by-southeast trending area, U. S. Route 95 leaves Las Vegas northwest and goes northwesterly through the northwest valley section, with Las Vegas Wash about 2 miles northeast. U. S.95 lies on the southwest perimeter of the valley bottomlands, a distorted surface, a playa-like region, occurs at the farthest northwest area, for about 15 to 18 miles, starting from Nevada Route 157. At Nevada Route 156,10 miles northwest, the surface, bottom land turns north. It lies at the drainage section of the Three Lakes Valley. The Corn Creek Dunes lie about 5 miles southwest of Route 156s intersection with U. S.95, the Las Vegas Valley is an area about 1,600 square miles. Only the U. S. Route 95 northwest follows an actual valley, the valley is a fault-bounded structural and hydrologic basin made of alluvial-fan deposits. There are several aquifers contained within the valley including the Las Vegas Aquifer and these heavily depleted water sources exist at about 660–980 feet in depth.
As of 1986, estimate show that the floor in Downtown Las Vegas has subsided by about 6.2 feet. The valley is an earthquake zone crossed by multiple fault. Corn Creek Dunes, trails. com 1959 Topographic map of the Las Vegas Valley area,1959
1970 United States Census
Microdata from the 1970 census are freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files and these data were originally created and disseminated by DUALabs. Personally identifiable information will be available in 2042, california took over as the most populous state, New York had previously been ranked number one. While the entire country increased to more than 204 million persons, four states lost population with West Virginia leading the list, down 8, historic US Census data 1971 U.

A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population, the term is used mostly in connection with national population and housing censuses, other common censuses include agriculture and traffic censuses. United Nations recommendations cover census topics to be collected, official definitions, the word is of Latin origin, during the Roman Republic, the census was a list that kept track of all adult males fit for military service. Current administrative data systems allow for other approaches to enumeration with the level of detail but raise concerns about privacy. A census can be contrasted with sampling in which information is obtained only from a subset of a population, typically main population estimates are updated by such intercensal estimates. Modern census data are used for research, business marketing, and planning. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling, stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations.
In some countries, the census provides the official used to apportion the number of elected representatives to regions. In many cases, a carefully chosen random sample can provide accurate information than attempts to get a population census. A census is often construed as the opposite of a sample as its intent is to count everyone in a rather than a fraction. However, population censuses rely on a frame to count the population. This is the way to be sure that everyone has been included as otherwise those not responding would not be followed up on. The fundamental premise of a census is that the population is not known, the use of a sampling frame is counterintuitive as it suggests that the population size is already known. However, a census is used to collect data on the individuals in the nation. This process of sampling marks the difference between historical census, which was a house to house process or the product of a decree. The sampling frame used by census is almost always an address register, thus it is not known if there is anyone resident or how many people there are in each household.
Depending on the mode of enumeration, a form is sent to the householder, as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, a particular problem is what are termed communal establishments which category includes student residences, religious orders, homes for the elderly, people in prisons etc
ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the travels more efficiently, and therefore more quickly. The basic format consists of five numerical digits, an extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code. The term ZIP Code was originally registered as a servicemark by the U. S. Postal Service, USPS style for ZIP is all caps and the c in code is capitalized, although style sheets for some publications use sentence case or lowercase. 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, Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16, by the early 1960s a more organized system was needed, and on July 1,1963, non-mandatory five-digit ZIP Codes were introduced nationwide.
Three months later, on October 1,1963, the U. S, an earlier list in June had proposed capitalized abbreviations ranging from two to five letters. The abbreviations have remained unchanged, with one exception, according to the historian of the U. S. Robert Moon, an employee of the post office, is considered the father of the ZIP Code, he submitted his proposal in 1944 while working as a postal inspector. The post office gives credit to Moon only for 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 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, Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight.
The United States Post Office used a character, which it called Mr. ZIP. He was often depicted with a such as USE ZIP CODE in the selvage of panes of stamps or on labels contained in, or the covers of. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called plus-four codes, add-on codes, or add ons. But initial attempts to promote use of the new format met with public resistance. For Post Office Boxes, the rule is that each box has its own ZIP+4 code. However, there is no rule, so the ZIP+4 Code must be looked up individually for each box. It is common to use add-on code 9998 for mail addressed to the postmaster,9999 for general delivery, for a unique ZIP Code, the add-on code is typically 0001
The poverty threshold, poverty limit or poverty line is the minimum level of income deemed adequate in a particular country. In practice, like the definition of poverty, the official or common understanding of the poverty line is higher in developed countries than in developing countries. In 2008, the World Bank came out with a figure of $1.25 at 2005 purchasing-power parity, the new IPL replaces the $1.25 per day figure, which used 2005 data. Most scholars agree that it better reflects todays reality, particularly new price levels in developing countries, the common international poverty line has in the past been roughly $1 a day. At present the percentage of the population living under extreme poverty is likely to fall below 10% according to the World Bank projections released in 2015. Determining the poverty line is usually done by finding the total cost of all the resources that an average human adult consumes in one year. Individual factors are used to account for various circumstances, such as whether one is a parent, elderly.
The poverty threshold may be adjusted annually, charles Booth, a pioneering investigator of poverty in London at the turn of the 20th century, popularised the idea of a poverty line, a concept originally conceived by the London School Board. Booth set the line at 10 to 20 shillings per week, to secure the necessaries of a healthy life, which included fuel and light, food and household and personal items. Based on data from leading nutritionists of the period, he calculated the cheapest price for the minimum calorific intake and nutritional balance necessary and he considered this amount to set his poverty line and concluded that 27. 84% of the total population of York lived below this poverty line. Rowntree distinguished between primary poverty, those lacking in income and secondary poverty, those who had enough income, Absolute poverty is the level of poverty as defined in terms of the minimal requirements necessary to afford minimal standards of food, health care and shelter. For the measure to be absolute, the line must be the same in different countries, such an absolute measure should look only at the individuals power to consume and it should be independent of any changes in income distribution.
Notice that if real income in an economy increases. Measuring poverty by a threshold has the advantage of applying the same standard across different locations and time periods. For example, a living in far northern Scandinavia requires a source of heat during colder months. The term absolute poverty is sometimes used as a synonym for extreme poverty. Absolute poverty is the absence of resources to secure basic life necessities. It depends not only on income but on access to services, safe drinking water, Water must not come solely from rivers and ponds, and must be available nearby

Las Vegas Range
The Las Vegas Range is an arid mountain range in Clark County, Nevada. The range is located in the southeast of the Desert National Wildlife Refuge, the Las Vegas Range is a north-south range, with two main north—south ridgelines. The highpoint of the range, Gass Peak is in the massif above the Las Vegas Valley. Region The range is on the southeast of the Sheep Range, both ranges are Basin and Range block faulted. To the east is another north—south Arrow Canyon Range, the U. S. Route 93 highway runs between the two ranges, and travels along the border of the Desert National Wildlife Refuge to the west.

Population density is a measurement of population per unit area or unit volume, it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans and it is a key geographical term. Population density is population divided by land area or water volume. Low densities may cause a vortex and lead to further reduced fertility. This is called the Allee effect after the scientist who identified it, commonly this may be calculated for a county, country, another territory, or the entire world. The worlds population is around 7,000,000,000, the worldwide human population density is around 7,000,000,000 ÷510,000,000 =13.7 per km2. If only the Earths land area of 150,000,000 km2 is taken into account and this includes all continental and island land area, including Antarctica. If Antarctica is excluded, population density rises to over 50 people per km2, 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, 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, for instance, Milwaukee has a greater population density when just the inner city is measured, and the surrounding suburbs excluded. 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. S.

Democratic Party (United States)
The Democratic Party is one of the two major contemporary political parties in the United States, along with the Republican Party. The Democrats dominant worldview was once socially conservative and fiscally classical liberalism, especially in the rural South, since Franklin D. Roosevelt and his New Deal coalition in the 1930s, the Democratic Party has promoted a social-liberal platform, supporting social justice. Today, the House Democratic caucus is composed mostly of progressives and centrists, the partys philosophy of modern liberalism advocates social and economic equality, along with the welfare state. It seeks to provide government intervention and regulation in the economy, the party has united with smaller left-wing regional parties throughout the country, such as the Farmer–Labor Party in Minnesota and the Nonpartisan League in North Dakota. Well into the 20th century, the party had conservative pro-business, the New Deal Coalition of 1932–1964 attracted strong support from voters of recent European extraction—many of whom were Catholics based in the cities.
After Franklin D. Roosevelts New Deal of the 1930s, the pro-business wing withered outside the South, after the racial turmoil of the 1960s, most southern whites and many northern Catholics moved into the Republican Party at the presidential level. The once-powerful labor union element became smaller and less supportive after the 1970s, white Evangelicals and Southerners became heavily Republican at the state and local level in the 1990s. However, African Americans became a major Democratic element after 1964, after 2000, Hispanic and Latino Americans, Asian Americans, the LGBT community, single women and professional women moved towards the party as well. The Northeast and the West Coast became Democratic strongholds by 1990 after the Republicans stopped appealing to socially liberal voters there, the Democratic Party has retained a membership lead over its major rival the Republican Party. The most recent was the 44th president Barack Obama, who held the office from 2009 to 2017, in the 115th Congress, following the 2016 elections, Democrats are the opposition party, holding a minority of seats in both the House of Representatives and the Senate.
The party holds a minority of governorships, and state legislatures, though they do control the mayoralty of cities such as New York City, Los Angeles, Chicago and Washington, D. C. The Democratic Party traces its origins to the inspiration of the Democratic-Republican Party, founded by Thomas Jefferson, James Madison and that party inspired the Whigs and modern Republicans. Organizationally, the modern Democratic Party truly arose in the 1830s, since the nomination of William Jennings Bryan in 1896, the party has generally positioned itself to the left of the Republican Party on economic issues. They have been liberal on civil rights issues since 1948. On foreign policy both parties changed position several times and that party, the Democratic-Republican Party, came to power in the election of 1800. After the War of 1812 the Federalists virtually disappeared and the national political party left was the Democratic-Republicans. The Democratic-Republican party still had its own factions, however.
As Norton explains the transformation in 1828, Jacksonians believed the peoples will had finally prevailed, through a lavishly financed coalition of state parties, political leaders, and newspaper editors, a popular movement had elected the president
A city is a large and permanent human settlement. Cities generally have complex systems for sanitation, land usage, housing, a big city or metropolis usually has associated suburbs and exurbs. Such cities are associated with metropolitan areas and urban areas. Once a city expands far enough to another city, this region can be deemed a conurbation or megalopolis. Damascus is arguably the oldest city in the world, in terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai. There is not enough evidence to assert what conditions gave rise to the first cities, some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces. The conventional view holds that cities first formed after the Neolithic revolution, the Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and to settle near others who lived by agricultural production, the increased population density encouraged by farming and the increased output of food per unit of land created conditions that seem more suitable for city-like activities.
In his book and Economic Development, Paul Bairoch takes up position in his argument that agricultural activity appears necessary before true cities can form. According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. To illustrate this point, Bairoch offers an example, Western Europe during the pre-Neolithic, when the cost of transport is taken into account, the figure rises to 200,000 square kilometres. Bairoch noted that this is roughly the size of Great Britain, the urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted. In his book City Economics, Brendan OFlaherty asserts Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages, OFlaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses.
Their applications are seen in more basic economic systems as well, increasing returns to scale occurs when doubling all inputs more than doubles the output an activity has economies of scale if doubling output less than doubles cost. To offer an example of these concepts, OFlaherty makes use of one of the oldest reasons why cities were built, in this example, the inputs are anything that would be used for protection and the output is the area protected and everything of value contained in it. OFlaherty asks that we suppose the protected area is square, the advantage is expressed as, O = s 2, where O is the output and s stands for the length of a side. This equation shows that output is proportional to the square of the length of a side, the inputs depend on the length of the perimeter, I =4 s, where I stands for the quantity of inputs. So there are increasing returns to scale, O = I2 /16 and this equation shows that with twice the inputs, you produce quadruple the output
