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.

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.

Minnesota is a state in the Upper Midwest and northern regions of the United States. Minnesota was admitted as the 32nd U. S. state on May 11, 1858, created from the eastern half of the Minnesota Territory. The state has a large number of lakes, is known by the slogan the "Land of 10,000 Lakes", its official motto is L'Étoile du Nord. Minnesota is the 12th largest in area and the 22nd most populous of the U. S. states. This area is the center of transportation, industry and government, while being home to an internationally known arts community; the remainder of the state consists of western prairies now given over to intensive agriculture. Minnesota was inhabited by various indigenous peoples for thousands of years prior to the arrival of Europeans. French explorers and fur traders began exploring the region in the 17th century, encountering the Dakota and Ojibwe/Anishinaabe tribes. Much of what is today Minnesota was part of the vast French holding of Louisiana, purchased by the United States in 1803.
Following several territorial reorganizations, Minnesota in its current form was admitted as the country's 32nd state on May 11, 1858. Like many Midwestern states, it remained centered on lumber and agriculture. During the 19th and early 20th centuries, a large number of European immigrants from Scandinavia and Germany, began to settle the state, which remains a center of Scandinavian American and German American culture. In recent decades, immigration from Asia, the Horn of Africa, the Middle East, Latin America has broadened its demographic and cultural composition; the state's economy has diversified, shifting from traditional activities such as agriculture and resource extraction to services and finance. Minnesota's standard of living index is among the highest in the United States, the state is among the best-educated and wealthiest in the nation; the word Minnesota comes from the Dakota name for the Minnesota River: The river got its name from one of two words in the Dakota language,'Mní sóta' which means "clear blue water", or'Mnißota', which means cloudy water.
Native Americans demonstrated the name to early settlers by dropping milk into water and calling it mnisota. Many places in the state have similar names, such as Minnehaha Falls, Minneota, Minnetonka and Minneapolis, a combination of mni and polis, the Greek word for "city". Minnesota is the second northernmost U. S. state and northernmost contiguous state. Its isolated Northwest Angle in Lake of the Woods county is the only part of the 48 contiguous states lying north of the 49th parallel; the state is part of the U. S. region known as part of North America's Great Lakes Region. It shares a Lake Superior water border with Michigan and a land and water border with Wisconsin to the east. Iowa is to the south, North Dakota and South Dakota are to the west, the Canadian provinces of Ontario and Manitoba are to the north. With 86,943 square miles, or 2.25% of the United States, Minnesota is the 12th-largest state. Minnesota has gneisses that are about 3.6 billion years old. About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean.
The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock. In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain; the Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock; this area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago, its bed created the fertile Red River valley, its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling.
Minnesota is geologically quiet today. The state's high point is Eagle Mountain at 2,301 feet, only 13 miles away from the low of 601 feet at the shore of Lake Superior. Notwithstanding dramatic local differences in elevation, much of the state is a rolling peneplain. Two major drainage divides meet in Minnesota's northeast in rural Hibbing, forming a triple watershed. Precipitation can follow the Mississippi River south to the Gulf of Mexico, the Saint Lawrence Seaway east to the Atlantic Ocean, or the Hudson Bay watershed to the Arctic Ocean; the state's nickname, "Land of 10,000 Lakes", is apt, as there are 11,842 Minnesota lakes over 10 acres in size. Minnesota's portion of Lake Superior is the largest at 962,700 acres and deepest body of wate
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, sleet, snow and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates", thus and mist are not precipitation but suspensions, because the water vapor does not condense sufficiently to precipitate. Two processes acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called "showers."Moisture, lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain occurs. A stationary front is present near the area of freezing rain and serves as the foci for forcing and rising air.
Provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. The cloud droplets will grow large enough to form raindrops and descend toward the Earth where they will freeze on contact with exposed objects. Where warm water bodies are present, for example due to water evaporation from lakes, lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones. Lake-effect snowfall can be locally heavy. Thundersnow is possible within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation. On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. Most precipitation is caused by convection; the movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes.
Precipitation is a major component of the water cycle, is responsible for depositing the fresh water on the planet. 505,000 cubic kilometres of water falls as precipitation each year. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres, but over land it is only 715 millimetres. Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on other celestial bodies, e.g. when it gets cold, Mars has precipitation which most takes the form of frost, rather than rain or snow. Precipitation is a major component of the water cycle, is responsible for depositing most of the fresh water on the planet. 505,000 km3 of water falls as precipitation each year, 398,000 km3 of it over the oceans. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective and orographic rainfall.
Convective processes involve strong vertical motions that can cause the overturning of the atmosphere in that location within an hour and cause heavy precipitation, while stratiform processes involve weaker upward motions and less intense precipitation. Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice. Mixtures of different types of precipitation, including types in different categories, can fall simultaneously. Liquid forms of precipitation include drizzle. Rain or drizzle that freezes on contact within a subfreezing air mass is called "freezing rain" or "freezing drizzle". Frozen forms of precipitation include snow, ice needles, ice pellets and graupel; the dew point is the temperature to which a parcel must be cooled in order to become saturated, condenses to water. Water vapor begins to condense on condensation nuclei such as dust and salt in order to form clouds. An elevated portion of a frontal zone forces broad areas of lift, which form clouds decks such as altostratus or cirrostratus.
Stratus is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. It can form due to the lifting of advection fog during breezy conditions. There are four main mechanisms for cooling the air to its dew point: adiabatic cooling, conductive cooling, radiational cooling, evaporative cooling. Adiabatic cooling occurs when air expands; the air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain. Conductive cooling occurs when the air comes into contact with a colder surface by being blown from one surface to another, for example from a liquid water surface to colder land. Radiational cooling occurs due to the emission of infrared radiation, either by the air or by the surface underneath. Evaporative cooling occurs when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or until it reaches saturation; the main ways water vapor is added to the air are: wind convergence into areas of upward motion, precipitation or virga falling from above, daytime heating evaporating water from the surface of oceans, water bodies or wet lan
Grand Forks County, North Dakota
Grand Forks County is a county in the U. S. state of North Dakota. As of the 2010 United States Census, its population was 66,861, making it the third-most populous county in North Dakota, its county seat and largest community is Grand Forks. Using territory annexed from Pembina County, the Dakota Territory legislature created Grand Forks County on January 4, 1873, its governing structure was not established at that time, nor was the territory attached to another county for administrative and judicial purposes. The government was organized on March 2, 1875; the county's boundaries were altered in 1875, 1881, 1883. It has retained its present boundary since 1883. Grand Forks County is included in ND-MN Metropolitan Statistical Area. Grand Forks County lies on the east side of North Dakota, its east boundary line abuts the west boundary line of the state of Minnesota. The Red River flows northward along the county's east border, on its way to Lake Winnipeg and Hudson Bay; the Forest River flows northerly across the upper western part of the county.
The terrain of Grand Forks County consists of low rolling hills, devoted to agriculture except around urban areas. The terrain slopes to the east; the county has a total area of 1,440 square miles, of which 1,436 square miles is land and 3.1 square miles is water. The University of North Dakota has established a Field Biology Station on Forest River, at the county's north border.

North Dakota is a U. S. state in northern regions of the United States. It is the nineteenth largest in area, the fourth smallest by population, the fourth most sparsely populated of the 50 states. North Dakota was admitted to the Union on November 3, 1889, along with its neighboring state, South Dakota, its capital is Bismarck, its largest city is Fargo. In the 21st century, North Dakota's natural resources have played a major role in its economic performance with the oil extraction from the Bakken formation, which lies beneath the northwestern part of the state; such development has led to reduced unemployment. North Dakota contains the tallest human-made structure in the KVLY-TV mast. North Dakota is a Midwestern state of the United States, it lies at the center of the North American continent. The geographic center of North America is near the town of Rugby. Bismarck is the capital of North Dakota, Fargo is the largest city. Soil is North Dakota's most precious resource, it is the base of the state's great agricultural wealth.
But North Dakota has enormous mineral resources. These mineral resources include billions of tons of lignite coal. In addition, North Dakota has large oil reserves. Petroleum was discovered in the state in 1951 and became one of North Dakota's most valuable mineral resources. In the early 2000's, the emergence of hydraulic fracturing technologies enabled mining companies to extract huge amounts of oil from the Bakken shale rock formation in the western part of the state. North Dakota's economy is based more on farming than are the economies of most other states. Many North Dakota factories manufacture farm equipment. Many of the state’s merchants rely on agriculture. Farms and ranches cover nearly all of North Dakota, they stretch from the flat Red River Valley in the east, across rolling plains, to the rugged Badlands in the west. The chief crop, wheat, is grown in nearly every county. North Dakota flaxseed, it is the country’s top producer of barley and sunflower seeds and a leader in the production of beans, lentils, oats and sugar beets.
Few white settlers came to the North Dakota region before the 1870's because railroads had not yet entered the area. During the early 1870's, the Northern Pacific Railroad began to push across the Dakota Territory. Large-scale farming began during the 1870's. Eastern corporations and some families established huge wheat farms covering large areas of land in the Red River Valley; the farms made such enormous profits. White settlers, attracted by the success of the bonanza farms, flocked to North Dakota increasing the territory's population. In 1870, North Dakota had 2,405 people. By 1890, the population had grown to 190,983. North Dakota was named for the Sioux people; the Sioux called meaning allies or friends. One of North Dakota's nicknames is the Peace Garden State; this nickname honors the International Peace Garden, which lies on the state's border with Manitoba, Canada. North Dakota is called the Flickertail State because of the many flickertail ground squirrels that live in the central part of the state.
North Dakota is in the U. S. region known as the Great Plains. The state shares the Red River of the North with Minnesota to the east. South Dakota is to the south, Montana is to the west, the Canadian provinces of Saskatchewan and Manitoba are to the north. North Dakota is near the middle of North America with a stone marker in Rugby, North Dakota marking the "Geographic Center of the North American Continent". With an area of 70,762 square miles, North Dakota is the 19th largest state; the western half of the state consists of the hilly Great Plains as well as the northern part of the Badlands, which are to the west of the Missouri River. The state's high point, White Butte at 3,506 feet, Theodore Roosevelt National Park are in the Badlands; the region is abundant in fossil fuels including crude oil and lignite coal. The Missouri River forms Lake Sakakawea, the third largest artificial lake in the United States, behind the Garrison Dam; the central region of the state is divided into the Missouri Plateau.
The eastern part of the state consists of the flat Red River Valley, the bottom of glacial Lake Agassiz. Its fertile soil, drained by the meandering Red River flowing northward into Lake Winnipeg, supports a large agriculture industry. Devils Lake, the largest natural lake in the state, is found in the east. Eastern North Dakota is overall flat. Most of the state is covered in grassland. Natural trees in North Dakota are found where there is good drainage, such as the ravines and valley near the Pembina Gorge and Killdeer Mountains, the Turtle Mountains, the hills around Devil's Lake, in the dunes area of McHenry County in central North Dakota, along the Sheyenne Valley slopes and the Sheyenne delta; this diverse terrain supports nearly 2,000 species of plants. North Dakota has a continental climate with cold winters; the temperature differences are significant because of its far inland position and being in the center of the Northern Hemisphere, with equal distances to the North Pole and the Equator.
As such, summers are subtropical, but winters are cold enough to ensure plant hardiness is low. Native American peoples lived in what is now North Dakota for thousands of year
