Zelinsky Model
The Zelinsky Model of Migration Transition, also known as the Migration Transition Model or Zelinsky's Migration Transition Model, claims that the type of migration that occurs within a country depends on its development level and its society type. It connects migration to the stages within the Demographic Transition Model (DTM). It was developed by Wilbur Zelinsky, professor of geography at Pennsylvania State University.{{Cite web, title=Wilbur Zelinsky memorial service planned for Oct. 26 {{!

Human Migration
Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is the dominant form of human migration globally.World Migration Report' Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty. Age is also important for both work and non-work migration. People may migrate as individuals, in family units or in Mass migration, large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/immigration. People moving from their home due to force ...

Country
A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, state with limited recognition, constituent country, or dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of "countries" in the world, since several states have disputed sovereignty status or limited recognition, and a number of non-sovereign entities are commonly considered countries. The definition and usage of the word "country" are flexible and have changed over time. '' The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Areas much smaller than a political entity may be referred to as a "country", such as the West Country in England, "big sky country" (used in various contexts of the American We ...

Demographic Transition Model
Demography () is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the interplay of fertility (births), mortality (deaths), and migration. Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population. Demographic analysis estimate ...

Wilbur Zelinsky
Wilbur Zelinsky (21 December 1921 – 4 May 2013) was an American cultural geographer. He was most recently a professor emeritus at Pennsylvania State University. He also created the Zelinsky Model of Demographic Transition. Background and education An Illinoisan by birth, but a "northeasterner by choice and conviction", Zelinsky received his Bachelor's Degree and his Master's Degree from the University of Madison, Wisconsin. He earned a PhD at University of California, Berkeley, where he was a student of Carl Sauer. Scholarship Zelinsky made numerous geographical studies of American popular culture, ranging from the diffusion of classical place-names to spatial patterns of personal given names and the spatial patterning of religious denominations. One of his most ambitious and imaginative projects was a provocative assessment of the impact of increasingly powerful personal preference on the spatial character of American society. During the 1960s, along with Gordon DeJong, ...

Geography
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and world, its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other Astronomical object, celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word Geography (Ptolemy), γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, w ...

Demographic Transition
In demography, demographic transition is a phenomenon and theory in the Social science, social sciences referring to the historical shift from high birth rates and high Mortality rate, death rates to low birth rates and low death rates as societies attain more technology, education (especially of female education, women), and economic development. The demographic transition has occurred in most of the world over the past two centuries, bringing the unprecedented population growth of the Malthusianism, post-Malthusian period, then reducing birth rates and population growth significantly in all regions of the world. The demographic transition strengthens economic growth process through three changes: a reduced dilution of capital and land stock, an increased investment in human capital, and an increased size of the labour force relative to the total population and changed age population distribution. Although this shift has occurred in many Developed country, industrialized countries ...

Urbanization
Urbanization (or urbanisation in British English) is the population shift from Rural area, 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 City, cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from Urban sprawl, urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of dr ...

Metropolitan Area
A metropolitan area or metro is a region consisting of a densely populated urban area, urban agglomeration and its surrounding territories which share Industry (economics), industries, commercial areas, Transport infrastructure, transport network, infrastructures and housing. A metropolitan area usually comprises multiple Principal city, principal cities, jurisdictions and Municipality, municipalities: Neighbourhood, neighborhoods, townships, boroughs, City, cities, towns, exurbs, suburbs, County, counties, districts and even State (polity), states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.In the United States, metropolitan areas are delineated around the Urban Area, core of a core based statistical area, which is defined as an urban area and includes central and outlying counties. In other countries metropolitan areas are sometimes anchored by one Core ...

Fertility
Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year (or longer) of unprotected sex. The antithesis of ''fertility'' is infertility, while the antithesis of ''fecundity'' is sterility. Demography In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to produce which is termed fecundity. While fertility can be measured, fecundity cannot be. Demographers measure the fertility rate in a variety of ways, which can be broa ...

Gravity Model Of Migration
The gravity model of migration is a model in urban geography derived from Newton's law of gravity, and used to predict the degree of migration interaction between two places. In 1941, astrophysicist John Q. Stewart applied Newton's law to the social sciences, establishing a theoretical foundation for the field of social physics. He recognized that the law of gravity could be used to explain demographic phenomena by examining empirical patterns related to distance in social interactions. This insight paved the way for further exploration of how physical principles could model social dynamics. Overview When used geographically, the words 'bodies' and 'masses' are replaced by 'locations' and 'importance' respectively, where importance can be measured in terms of population numbers, gross domestic product, or other appropriate variables. The gravity model of migration is therefore based upon the idea that as the importance of one or both of the location increases, there will also be ...
