The depopulation of the Great Plains refers to the large-scale migration of people from rural areas of the Great Plains of the United States to more urban areas and to the east and west coasts during the 20th century. This phenomenon of rural-to-urban migration has occurred to some degree in most areas of the United States, but has been especially pronounced in the Great Plains states, including Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota, Montana, Wyoming, Colorado, and New Mexico. Many Great Plains counties have lost more than 60 percent of their former populations.
Depopulation began in the early 1900s, accelerated in the Dust Bowl years of the 1930s, and has generally continued through the national census in 2010. The population decline has been broadly attributed to numerous factors, especially changes in agricultural practices, rapid improvements in urban transit and regional connectivity, and a declining rural job market.
Definitions vary as to what land comprises the Great Plains. The entire states of Kansas, Nebraska, South Dakota, and North Dakota are often considered part of the Great Plains. The Great Plains extend to parts of six additional states: Texas, Oklahoma, New Mexico, Colorado, Wyoming, and Montana. The eastern boundary is about 97 degrees W longitude and the Plains extend westward to the Rocky Mountains and southward from the border with Canada to the approximate latitude of Austin, Texas. [1] A somewhat more restrictive definition by the U.S. Census Bureau gives a total area of the Great Plains in the United States as 533,100 square miles (1,381,000 km2), 18 percent of the area of the entire United States. [2]
The Great Plains are distinguished by generally flat land and a natural vegetation cover consisting mostly of expansive grasslands. The eastern part of the Great Plains is dominated by agriculture, with wheat being the most common and important crop. The western part is more arid and is primarily used for grazing cattle and irrigated agriculture.
Large-scale settlement of the Great Plains by farmers and ranchers began with the end of the Civil War in 1865. By the late 1870s the Plains Indians had been defeated militarily and were largely confined to reservations. Drawn by the free land made available by the Homestead Act, pioneer families quickly settled the region such that nearly all of the arable land was privately owned or on Indian reservations by 1900.
The initial rush to settle the Great Plains by hundreds of thousands of farmers and ranchers has been reversed because of several factors. Perhaps the most significant reasons have been economic. Over the course of the 20th century, farm economies saw dramatic shifts from small-scale family subsistence farming to larger commercial farms utilizing more equipment and less labor. [3] Many family farms proved to be too small to survive. Farmers also used farming techniques which were unsuited to the dry, windy climate and the frequent droughts of the Great Plains. This became manifest during the Dust Bowl years of the 1930s, in which rural flight from the Great Plains accelerated, although the decline in population of some counties had begun as early as 1900. [4] Better roads and the automobile permitted many farmers to live in larger towns and cities rather than on the farm itself. While urban areas on the Great Plains more than doubled in population, thousands of small towns and communities disappeared. Two-thirds of counties lost some part of their population between the early 1900s and the 2010 census, and, as the table below demonstrates, many rural counties lost more than 60 percent of their population. A few counties lost more than 80 percent of their population. Population density of some Great Plains counties dipped below two persons per square mile. [5] [6] [7]
Governments have tried a variety of methods to stem the outflow of population from rural areas in the Great Plains. Some towns have offered free building lots to prospective residents, but the program has met with only limited success. The fundamental problem appears to be the few employment opportunities available in these small and isolated communities. [8]
The population decline has led to proposals to return the land to its natural state and under public ownership. The Buffalo Commons proposal calls for large portions of the drier regions of the Great Plains to be returned to their original condition as pasture land for American bison and other plains animals. [9]
The following Great Plains counties lost more than 60 percent of their population from the census year when they attained their highest population until 2010.

Rural flight is the migratory pattern of people from rural areas into urban areas. It is urbanization seen from the rural perspective.
South Dakota is a landlocked state in the North Central region of the United States. It is also part of the Great Plains. South Dakota is named after the Dakota Sioux tribe, which comprises a large portion of the population with nine reservations currently in the state and has historically dominated the territory. South Dakota is the 17th largest by area, but the 5th least populous, and the 5th least densely populated of the 50 United States. Pierre is the state capital, and Sioux Falls, with a population of about 213,900, is South Dakota's most populous city. The state is bisected by the Missouri River, dividing South Dakota into two geographically and socially distinct halves, known to residents as "East River" and "West River". South Dakota is bordered by North Dakota to the north, Minnesota to the east, Iowa to the southeast, Nebraska to the south, Wyoming to the west, and Montana to the northwest.
The Great Plains, sometimes simply "the Plains", is a broad expanse of flatland in North America. It is located just to the east of the Rocky Mountains, much of it covered in prairie, steppe, and grassland. It is the western part of the Interior Plains, which also include the mixed grass prairie, the tallgrass prairie between the Great Lakes and Appalachian Plateau, and the Taiga Plains and Boreal Plains ecozones in Northern Canada. Great Plains or Western Plains is also used to describe the ecoregion of the Great Plains, or alternatively the western portion of the Great Plains.
Center-pivot irrigation, also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers. A circular area centered on the pivot is irrigated, often creating a circular pattern in crops when viewed from above. Most center pivots were initially water-powered, however today most are propelled by electric motors.
The Dust Bowl was the result of a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of natural factors and human-made factors: a failure to apply dryland farming methods to prevent wind erosion, most notably the destruction of the natural topsoil by settlers in the region. The drought came in three waves: 1934, 1936, and 1939–1940, but some regions of the High Plains experienced drought conditions for as long as eight years.
Kingsbury County is a county in the U.S. state of South Dakota. As of the 2020 census, the population was 5,187. Its county seat is De Smet. The county was created in 1873, and was organized in 1880. It was named for brothers George W. and T. A. Kingsbury, descendants of the colonial English Kingsbury family in Boston, Massachusetts. They were prominently involved in the affairs of Dakota Territory and served as elected members of several Territorial Legislatures.
The Ogallala Aquifer is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km2) in portions of eight states. It was named in 1898 by geologist N. H. Darton from its type locality near the town of Ogallala, Nebraska. The aquifer is part of the High Plains Aquifer System, and resides in the Ogallala Formation, which is the principal geologic unit underlying 80% of the High Plains.
North Dakota was first settled by Native Americans several thousand years ago. The first Europeans explored the area in the 18th century establishing some limited trade with the natives.
The Oklahoma Panhandle is a salient in the extreme northwestern region of the U.S. state of Oklahoma, consisting of Cimarron County, Texas County and Beaver County, from west to east. As with other salients in the United States, its name comes from the similarity of its shape to the handle of a pan. Its largest city is Guymon in Texas County. Black Mesa State Park, located in Cimarron County, is the highest point in the state. Other points of interest include Beaver Dunes Park, Optima Lake, and the Optima National Wildlife Refuge. Oklahoma Panhandle State University is ten miles away from Guymon.
The history of agriculture in the United States covers the period from the first English settlers to the present day. In Colonial America, agriculture was the primary livelihood for 90% of the population, and most towns were shipping points for the export of agricultural products. Most farms were geared toward subsistence production for family use. The rapid growth of population and the expansion of the frontier opened up large numbers of new farms, and clearing the land was a major preoccupation of farmers. After 1800, cotton became the chief crop in southern plantations, and the chief American export. After 1840, industrialization and urbanization opened up lucrative domestic markets. The number of farms grew from 1.4 million in 1850, to 4.0 million in 1880, and 6.4 million in 1910; then started to fall, dropping to 5.6 million in 1950 and 2.2 million in 2008.
The Buffalo Commons is a conceptual proposal to create a vast nature preserve by returning 139,000 square miles (360,000 km2) of the drier portion of the Great Plains to native prairie, and by reintroducing the American bison ("buffalo"), that once grazed the shortgrass prairie. The proposal would affect ten states: Montana, Wyoming, Colorado, Oklahoma, New Mexico, Texas, North Dakota, South Dakota, Nebraska, and Kansas.
The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. The High Plains are located in eastern Montana, southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico, the Oklahoma Panhandle, and the Texas Panhandle. The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or on satellite maps. From east to west, the High Plains rise in elevation from around 1,800 to 7,000 ft.
The Great Sioux Reservation initially set aside land west of the Missouri River in South Dakota and Nebraska for the use of the Sioux, who had dominated this territory. The reservation was established in the Fort Laramie Treaty of 1868. It included all of present-day western South Dakota and modern Boyd County, Nebraska. This area was established by the United States as a reservation for the Teton Sioux, also known as the Lakota: the seven western bands of the "Seven Council Fires".
West River is the portion of the state of South Dakota located west of the Missouri River; it contains more than one-half of the land area and between one-quarter and one-third of the population of the state.
Rural areas in the United States, often referred to as rural America, consists of approximately 97% of the United States' land area. An estimated 60 million people, or one in five residents, live in rural America. Definitions vary from different parts of the United States government as to what constitutes those areas.
The history of the U.S. state of Nebraska dates back to its formation as a territory by the Kansas–Nebraska Act, passed by the United States Congress on May 30, 1854. The Nebraska Territory was settled extensively under the Homestead Act of 1862 during the 1860s, and in 1867 was admitted to the Union as the 37th U.S. state. The Plains Indians are the descendants of a long line of succeeding cultures of indigenous peoples in Nebraska who occupied the area for thousands of years before European arrival and continue to do so today.
The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama and buffalograss, the two less dominant grasses in the prairie are greasegrass and sideoats grama. The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less precipitation than that of the tall and mixed grass prairies to the east.
The history of South Dakota describes the history of the U.S. state of South Dakota over the course of several millennia, from its first inhabitants to the recent issues facing the state.
Wheat is produced in almost every state in the United States, and is one of the most grown grains in the country. The type and quantity vary between regions. The US is ranked fourth in production volume of wheat, with almost 50 million tons produced in 2020, behind only China, India and Russia. The US is ranked first in crop export volume; almost 50% of its total wheat production is exported.
Agriculture on the precontact Great Plains describes the agriculture of the Indigenous peoples of the Great Plains of the United States and southern Canada in the Pre-Columbian era and before extensive contact with European explorers, which in most areas occurred by 1750. The principal crops grown by Indian farmers were maize (corn), beans, and squash, including pumpkins. Sunflowers, goosefoot, tobacco, gourds, and plums, were also grown.
