Rural flight is the migratory pattern of people from rural areas into urban areas. It is urbanization seen from the rural perspective.
A suburb is an area within a metropolitan area which has a higher or lower population density and sometimes less detached housing. In many metropolitan areas suburbs rise in population during the day and are where most jobs are located; being major commercial and job hubs, many suburbs also exist as separate residential communities within commuting distance of a larger city. Suburbs can have their own political or legal jurisdiction, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries, suburban areas are defined in contrast to central city or inner city areas, but in Australian English and South African English, suburb has become largely synonymous with what is called a "neighborhood" in the U.S., but it is used in contrast with inner city areas.
Urbanization is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas.
A ghetto is a part of a city in which members of a minority group are concentrated, especially as a result of political, social, legal, religious, environmental or economic pressure. Ghettos are often known for being more impoverished than other areas of the city. Versions of such restricted areas have been found across the world, each with their own names, classifications, and groupings of people.
A slum is a highly populated urban residential area consisting of densely packed housing units of weak build quality and often associated with poverty. The infrastructure in slums is often deteriorated or incomplete, and they are primarily inhabited by impoverished people. Although slums are usually located in urban areas, in some countries they can be located in suburban areas where housing quality is low and living conditions are poor. While slums differ in size and other characteristics, most lack reliable sanitation services, supply of clean water, reliable electricity, law enforcement, and other basic services. Slum residences vary from shanty houses to professionally built dwellings which, because of poor-quality construction or lack of basic maintenance, have deteriorated.
In general, a rural area or a countryside is a geographic area that is located outside towns and cities. Typical rural areas have a low population density and small settlements. Agricultural areas and areas with forestry are typically described as rural, as well as other areas lacking substantial development. Different countries have varying definitions of rural for statistical and administrative purposes.
The Great Migration, sometimes known as the Great Northward Migration or the Black Migration, was the movement of six million African Americans out of the rural Southern United States to the urban Northeast, Midwest, and West between 1910 and 1970. It was substantially caused by poor economic and social conditions due to prevalent racial segregation and discrimination in the Southern states where Jim Crow laws were upheld. In particular, continued lynchings motivated a portion of the migrants, as African Americans searched for social reprieve. The historic change brought by the migration was amplified because the migrants, for the most part, moved to the then-largest cities in the United States at a time when those cities had a central cultural, social, political, and economic influence over the United States; there, African-Americans established culturally influential communities of their own. According to Isabel Wilkerson, despite the loss of leaving their homes in the South, and the barriers faced by the migrants in their new homes, the migration was an act of individual and collective agency, which changed the course of American history, a "declaration of independence" written by their actions.
White flight or white exodus is the sudden or gradual large-scale migration of white people from areas becoming more racially or ethnoculturally diverse. Starting in the 1950s and 1960s, the terms became popular in the United States. They referred to the large-scale migration of people of various European ancestries from racially mixed urban regions to more racially homogeneous suburban or exurban regions. The term has more recently been applied to other migrations by whites, from older, inner suburbs to rural areas, as well as from the American Northeast and Midwest to the milder climate in the Southeast and Southwest. The term 'white flight' has also been used for large-scale post-colonial emigration of whites from Africa, or parts of that continent, driven by levels of violent crime and anti-colonial or anti-white state policies.
Urban sprawl is defined as "the spreading of urban developments on undeveloped land near a more or less densely populated city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.
The urbanization of most of Africa is moving fast forward, especially south of the Sahara. It is estimated that in 1900, about 89% of inhabitants lived from the primary occupations of farming, hunting & gathering, cattle nomadism, and fishing meaning that 11% or less were urban. At the start of the independence period in 1957, 14.7% of Africa's inhabitants were urban, in 2000 had it risen to 37.2% and it is expected to rise to 49.3% in 2015, in effect 3.76% to 3.35% per year. In sub-Saharan Africa in 1960 "only one city, Johannesburg, had a population of one million;...in 2009, there were fifty-two cities with such large populations." The Nigerian city of Lagos that in 1963 had 665,000 inhabitants and 8.7 million in 2000 is expected to become the world's 11th biggest city by 2015 with 16 million inhabitants.
Suburbanization (AE), or suburbanisation (BE), is a population shift from historic core cities or rural areas into suburbs, resulting in the formation of (sub)urban sprawl. As a consequence of the movement of households and businesses away from city centers, low-density, peripheral urban areas grow.
Urban decay is the sociological process by which a previously functioning city, or part of a city, falls into disrepair and decrepitude. There is no single process that leads to urban decay.
The history of African Americans in Chicago or Black Chicagoans dates back to Jean Baptiste Point du Sable's trading activities in the 1780s. Du Sable, the city's founder, was Haitian of African and French descent. Fugitive slaves and freedmen established the city's first black community in the 1840s. By the late 19th century, the first black person had been elected to office.
Counterurbanization, or deurbanization, is a demographic and social process whereby people move from urban areas to rural areas. It is, like suburbanization, inversely related to urbanization. It first occurred as a reaction to inner-city deprivation. More recent research has documented the social and political drivers of counterurbanization and its impacts in developing countries such as China, which are currently undergoing the process of mass urbanization. It is one of the causes that can lead to shrinking cities.
Shrinking cities or urban depopulation are dense cities that have experienced a notable population loss. Emigration is a common reason for city shrinkage. Since the infrastructure of such cities was built to support a larger population, its maintenance can become a serious concern. A related phenomenon is counterurbanization.
In the context of the 20th-century history of the United States, the Second Great Migration was the migration of more than 5 million African Americans from the South to the Northeast, Midwest and West. It began in 1940, through World War II, and lasted until 1970. It was much larger and of a different character than the first Great Migration (1916–1940), where the migrants were mainly rural farmers from the South and only came to the Northeast and Midwest.
Black flight is a term applied to the migration of African Americans from predominantly black or mixed inner-city areas in the United States to suburbs and newly constructed homes on the outer edges of cities. While more attention has been paid to this since the 1990s, the movement of black people to the suburbs has been underway for some time, with nine million people having migrated from 1960 to 2000. Their goals have been similar to those of the white middle class, whose out-migration was called white flight: newer housing, better schools for their children, and attractive environments. From 1990 to 2000, the percentage of African Americans who lived in the suburbs increased to a total of 39 percent, rising 5 percentage points in that decade. Most who moved to the suburbs after World War II were middle class.
Ethnic succession theory is a theory in sociology stating that ethnic and racial groups entering a new area may settle in older neighborhoods or urban areas until achieving economic parity with certain economic classes. The concept of succession is well established in "both ecological and economic models of urban residential change." As the newer group becomes economically successful, it moves to a better residential area. With continued immigration, a new ethnic group will settle in the older neighborhood in a similar starting situation. This pattern will continue, creating a succession of groups moving through the neighborhood over time. Ethnic succession has taken place in most major United States cities, but is most well known in New York City, where this process has been observed since the 19th century.
African-American neighborhoods or black neighborhoods are types of ethnic enclaves found in many cities in the United States. Generally, an African American neighborhood is one where the majority of the people who live there are African American. Some of the earliest African-American neighborhoods were in New Orleans, Mobile, Atlanta, and other cities throughout the American South, as well as in New York City. In 1830, there were 14,000 "Free negroes" living in New York City.
Overurbanization is a thesis originally developed by scholars of demography, geography, ecology, economics, political science, and sociology in thrergence of International Nongovernmental Organizations Amid Declining States. The term is intentionally comparative and has been used to differentiate between developed and developing countries. Several causes have been suggested, but the most common is rural-push and urban-pull factors in addition to population growth.
