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. 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. 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. 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. 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. ==Counties with large population losses==
