Net migration rates for 2008: positive (blue), negative (orange), stable (green), and no data (gray).

Human migration is physical movement by humans from one district to another, sometimes over long distances or in large groups. The movement of populations in modern times has continued under the form of both voluntary migration within one's region, country, or beyond, and involuntary migration (which includes the slave trade, trafficking in human beings and ethnic cleansing). People who migrate are called migrants, or, more specifically, emigrants, immigrants, or settlers, depending on historical setting, circumstances and perspective.

The pressures of human migrations, whether as outright conquest or by slow cultural infiltration and resettlement, have affected the grand epochs in history (for example, the Decline of the Roman Empire); under the form of colonization, migration has transformed the world (such as the prehistoric and historic settlements of Australia and the Americas). Population genetics studied in traditionally settled modern populations have opened a window into the historical patterns of migrations, a technique pioneered by Luigi Luca Cavalli-Sforza.

Forced migration has been a means of social control under authoritarian regimes, yet free initiative migration is a powerful factor in social adjustment and the growth of urban populations.

In December 2003 The Global Commission on International Migration (GCIM) was launched with the support of Secretary-General of the United Nations Kofi Annan and several countries, with an independent 19-member Commission, a threefold mandate and a finite life-span ending December 2005. Its report, based on regional consultation meetings with stakeholders and scientific reports from leading international migration experts, was published and presented to Kofi Annan on 5 October 2005.[1]

Pre-modern migrations

2nd to 5th century Migration Period.

Historical migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about a million years ago. Homo sapiens appear to have occupied all of Africa about 150,000 years ago, moved out of Africa 70,000 years ago, and had spread across Australia, Asia and Europe by 40,000 years BPE. Migration to the Americas took place 20,000 to 15,000 years ago, and by 2,000 years ago, most of the Pacific Islands were colonized. Later population movements notably include the Neolithic Revolution, Indo-European expansion, and the Early Medieval Great Migrations including Turkic expansion.

Early humans migrated due to many factors such as changing climate and lanscape and inaddequate food supply. The evidence indicates that the ancestors of the Austronesian peoples spread from the South Chinese mainland to Taiwan at some time around 8,000 years ago. Evidence from historical linguistics suggests that it is from this island that seafaring peoples migrated, perhaps in distinct waves separated by millennia, to the entire region encompassed by the Austronesian languages. It is believed that this migration began around 6,000 years ago.[2] Indo-Aryan migration to and within Northern India is presumed to have taken place in the Middle to Late Bronze Age, contemporary to the Late Harappan phase in India (ca. 1700 to 1300 BC). From 180 BC, a series of invasions from Central Asia followed, including those led by the Indo-Greeks, Indo-Scythians, Indo-Parthians and Kushans in the north-western Indian subcontinent.[3][4][5]

From about 750 BC the Greeks began 250 years of expansion, settling colonies in all directions. In Europe two waves of migrations dominate demographic distributions, that of the Celtic people, and the later Migration Period from the east. Other examples are small movements like ancient Scots moving from Hibernia to Caledonia and Magyars into Pannonia (modern-day Hungary). Turkic peoples spread across most of Central Asia into Europe and the Middle East between the 6th and 11th centuries. Recent research suggests that the Madagascar was uninhabited until Austronesian seafarers from Indonesia arrived during the 5th and 6th centuries AD. Subsequent migrations from both the Pacific and Africa further consolidated this original mixture, and Malagasy people emerged.[6]

One common hypothesis of the Bantu expansion.

Before the expansion of the Bantu languages and their speakers, the southern half of Africa is believed to have been populated by Pygmies and Khoisan speaking people, today occupying the arid regions around the Kalahari Desert and the forest of Central Africa. By about 1000 AD Bantu migration had reached modern day Zimbabwe and South Africa. The Banu Hilal and Banu Ma'qil were a collection of Arab Bedouin tribes from the Arabian Peninsula who migrated westwards via Egypt between the 11th and 13th centuries. Their migration strongly contributed to the arabization and islamization of the western Maghreb, which was until then dominated by Berber tribes. Ostsiedlung was the medieval eastward migration and settlement of Germans. The 13th century was the time of the great Mongol and Turkic migrations across Eurasia.[7]

Between the 11th and 18th centuries, the Vietnamese expanded southward in a process known as nam tiến (southward expansion).[8] Manchuria was separated from China proper by the Inner Willow Palisade, which restricted the movement of the Han Chinese into Manchuria during the Qing Dynasty, as the area was off-limits to the Han until the Qing started colonizing the area with them later on in the dynasty's rule.[9]

The Age of Exploration and European Colonialism led to an accelerated pace of migration since Early Modern times. In the 16th century perhaps 240,000 Europeans entered American ports.[10] In the 19th century over 50 million people left Europe for the Americas.[11] The local populations or tribes, such as the Aboriginal people in Canada, Brazil, Argentina, Australia, Japan[12] and the United States, were usually far overwhelmed numerically by the settlers. More recent examples are the movement of ethnic Chinese into Tibet and Xinjiang[13], ethnic Javanese into Western New Guinea and Kalimantan[14] (see Transmigration program), Brazilians into Amazonia[15], Israelis into the West Bank and Gaza, ethnic Arabs into Iraqi Kurdistan, and ethnic Russians into Siberia and Central Asia.[16]

Modern migrations

Industrialization

While the pace of migration had accelerated since the 18th century already (including the involuntary slave trade), it would increase further in the 19th century. Manning distinguishes three major types of migration: labor migration, refugee migrations, and urbanization. Millions of agricultural workers left the countryside and moved to the cities causing unprecedented levels of urbanization. This phenomenon began in Britain in the late 18th century and spread around the world and continues to this day in many areas.

Industrialization encouraged migration wherever it appeared. The increasingly global economy globalized the labor market. The Atlantic slave trade diminished sharply after 1820, which gave rise to self-bound contract labor migration from Europe and Asia to plantations. Overpopulation[citation needed], open agricultural frontiers, and rising industrial centers attracted voluntary migrant. Moreover, migration was significantly made easier by improved transportation techniques.

Transnational labor migration reached a peak of three million migrants per year in the early twentieth century. Italy, Norway, Ireland and the Quongdong region of China were regions with especially high emigration rates during these years. These large migration flows influenced the process of nation state formation in many ways. Immigration restrictions have been developed, as well as diaspora cultures and myths that reflect the importance of migration to the foundation of certain nations, like the American melting pot. The transnational labor migration fell to a lower level from 1930s to the 1960s and then rebounded.

The United States experienced considerable internal migration related to industrialization, including its African American population. From 1910–1970, approximately 7 million African Americans migrated from the rural Southern United States, where blacks faced both poor economic opportunities and considerable political and social prejudice, to the industrial cities of the Northeast, Midwest and West where relatively well paid jobs were available.[17] This phenomenon came to be known in the United States as its own Great Migration.

The twentieth century experienced also an increase in migratory flows caused by war and politics. Muslims moved from the Balkan to Turkey, while Christians moved the other way, during the collapse of the Ottoman Empire. 400,000 Jews moved to Palestine in the early twentieth century. The Russian Civil War caused some 3 million Russians, Poles and Germans to migrate out of the Soviet Union. World War II and decolonization also caused migrations.[18][19]

World War II

See World War II evacuation and expulsion and Population transfer in the Soviet Union for World War II forced migrations.

The Jewish communities across Europe, the Mediterranean and the Middle East were formed from voluntary and involuntary migrants. After the Holocaust (1938 to 1945), there was increased migration to the British Mandate of Palestine, which became the modern state of Israel as a result of the United Nations Partition Plan for Palestine.

Provisions of the Potsdam Agreement from 1945 signed by victorious Western Allies and the Soviet Union led to one of the largest European migrations, and the largest in the 20th century. It involved the migration and resettlement of close to or over 20 million people. The largest affected group were 16.5 million Germans expelled from Eastern Europe westwards. The second largest group were Poles, millions of whom were expelled westwards from eastern Kresy region and resettled in the so-called Recovered Territories (see Allies decide Polish border in the article on the Oder-Neisse line). Hundreds of thousands of Poles, Ukrainians (Operation Wisła), Lithuanians, Latvians, Estonians and some Belarusians, were expelled eastwards from Europe to the Soviet Union. Finally, many of the several hundred thousand Jews remaining in the Eastern Europe after the Holocaust migrated outside Europe to Israel and the United States.

India

Rural Sikhs in a long ox-cart train heading towards India. Margaret Bourke-White, 1947. The migration was a "massive exercise in human misery," wrote Bourke-White.

In 1947, upon the Partition of India, large populations moved from India to Pakistan and vice versa, depending on their religious beliefs. The partition was promulgated in the Indian Independence Act 1947 as a result of the dissolution of the British Indian Empire. The partition displaced up to 12.5 million people in the former British Indian Empire, with estimates of loss of life varying from several hundred thousand to a million.[20]Muslim residents of the former British India migrated to Pakistan, whilst Hindu and Sikh residents of Pakistan moved in the opposite direction.

In modern India, estimates based on industry sectors mainly employing migrants suggest that there are around 100 million circular migrants in India. Caste, social networks and historical precedents play a powerful role in shaping patterns of migration. Migration for the poor is mainly circular, as despite moving temporarily to urban areas, they lack the social security which might keep them there more permanently. They are also keen to maintain a foothold in home areas during the agricultural season.

Research by the Overseas Development Institute identifies a rapid movement of labour from slower to faster growing parts of the economy. Migrants can often find themselves excluded by urban housing policies and migrant support initiatives are needed to give workers improved access to market information, certification of identity, housing and education.[21]

Theories

Ravenstein

Certain laws of social science have been proposed to describe human migration. The following was a standard list after Ravenstein's proposals during the time frame of 1834 to 1913. The laws are as follows:

  1. every migration flow generates a return or countermigration.
  2. the majority of migrants move a short distance.
  3. migrants who move longer distances tend to choose big-city destinations
  4. urban residents are less migratory than inhabitants of rural areas.
  5. families are less likely to make international moves than young adults.

Lee

Lee's Push-pull theory divides factors causing migrations into two groups of factors: Push and pull factors. Push and pull factors are those factors which either forcefully push people into migration or attract them to an area.[22]

Push Factors

  • Not enough jobs
  • Few opportunities
  • Primitive conditions
  • Desertification
  • Famine or drought
  • Political fear or persecution
  • Poor medical care
  • Loss of wealth
  • Natural disasters
  • Death threats
  • Slavery
  • Pollution
  • Poor housing
  • Landlord/tenant issues
  • Bullying
  • Discrimination
  • Poor chances of marrying

Pull Factors

  • Job opportunities
  • Better living conditions
  • Political and/or religious freedom
  • Enjoyment
  • Education
  • Better medical care
  • Security
  • Family links
  • Industry
  • Better chances of marrying

Climate cycles

The modern field of climate history suggests that the successive waves of Eurasian nomadic movement throughout history have had their origins in climatic cycles, which have expanded or contracted pastureland in Central Asia, especially Mongolia and the Altai. People were displaced from their home ground by other tribes trying to find land that could be grazed by essential flocks, each group pushing the next further to the south and west, into the highlands of Anatolia, the plains of Hungary, into Mesopotamia or southwards, into the rich pastures of China.

Net migration rates for 2006: positive (blue), negative (orange) and stable (green).

Human migration denotes any movement by humans from one locality to another, often over long distances or in large groups. Humans are known to have migrated extensively throughout history and prehistory.

Migration and population isolation is one of the four evolutionary forces (along with natural selection, genetic drift, and mutation). The study of the distribution of and change in allele (gene variations) frequencies under such influences is the discipline of Population genetics.

The movement of populations in modern times has continued under the form of both voluntary migration within one's region, country, or beyond, and involuntary migration (which includes slave trade, Trafficking in human beings and ethnic cleansing). The people who migrate are called migrants, or, more specifically, emigrants, immigrants or settlers, depending on historical setting, circumstance and perspective.

Overview

There is only one evolutionary mechanism: this mechanism is 'selection' both in natural form and in un-natural form(i.e. breeding by cultural(human) intervention); selection acts on physical structures both at the gene level (indirectly) and at the cultural (see memes)level (directly); all other phenomena, such as population isolation, are results of the selection mechanisms at work, they are not evolutionary forces.

Different types of migration include:

  • Daily human commuting.
  • Seasonal human migration is mainly related to agriculture.
  • Permanent migration, for the purposes of permanent or long-term stays.
  • Local
  • Regional
  • Rural to Urban, more common in developing countries as industrialization takes effect (urbanization)
  • Urban to Rural, more common in developed countries due to a higher cost of urban living (see white flight)
  • International migration

Human migration has taken place at all times and in the greatest variety of circumstances. It has been tribal, national, class and individual. Its causes have been climatic, political, economic, religious, or more love of adventure. Its causes and results are fundamental for the study of ethnology, of political and social history, and of political economy.

The pressures of human migrations, whether as outright conquest or by slow cultural infiltration and resettlement, have affected the grand epochs in history (e.g. the fall of the Western Roman Empire); under the form of colonization, migration has transformed the world (e.g. the prehistoric and historic settlements of Australia and the Americas). Population genetics studied in traditionally settled modern populations have opened a window into the historical patterns of migrations, a technique pioneered by Luigi Luca Cavalli-Sforza.

Push and Pull Factors

Push and Pull factors are those factors which either forcefully push someone into migration or attract them. A push factor is a forceful factor, and a factor which relates to the country the person is migrating from. It is generally a problem which the results in people wanting to migrate. Different types of Push Factors can be seen further below. A pull factor is something concerning the country a person migrates to. It is generally a good thing that attracts people to a certain place. Push and Pull factors are usually considered as north and south poles on a magnet. The idea is to have the attraction in the middle, i.e the place.

Push Factors

  • Not enough jobs
  • Few opportunities
  • Primitive Conditions
  • Political fear
  • Poor Medical Care
  • Not being able to practice religion
  • Loss of wealth
  • Natural Disasters

Pull Factors

  • Chances of getting a job
  • Better living standards
  • Political and/or religious freedom
  • Enjoyment
  • Education

Pre-modern migrations

Main article: Historical migration

Historical migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about a million years ago. Homo sapiens appear to have colonised all of Africa about 150 thousand years ago, moved out of Africa 80 thousand years ago, and spread across Eurasia and to Australia 40 thousand years ago. Migration to the Americas took place 20 to 15 thousand years ago, and by 2 thousand years ago, most of the Pacific Islands were colonised. Later population movements notably include the Neolithic revolution, Indo-European expansion, and the Early Medieval Great Migrations including Turkic expansion. The Age of Exploration and European Colonialism led to an accelerated pace of migration since Early Modern times.

Modern migrations

Industrialization

While the pace of migration had accelerated since the 18th century already (including the involuntary slave trade), it would increase further in the 19th century. Manning distinguishes three major types of migration: labour migration, refugee migrations and lastly: urbanization. Millions of agricultural workers left the countryside and moved to the cities causing unprecedented levels of urbanization. This phenomenon began in Britain in the late 18th century and spread around the world and continues to this day in many areas.

Industrialization encouraged migration wherever it appeared. The increasingly global economy globalised the labour market. Atlantic slave trade diminished sharply after 1820, which gave rise to self-bound contract labour migration from Europe and Asia to plantations. Also overpopulation, open agricultural frontiers and rising industrial centres attracted voluntary, encouraged and sometimes coerced migration. Moreover, migration was significantly eased by improved transportation techniques.

During this same period similar large numbers of people migrated over large distances within Asia. Southeastern Asia received 50 million migrants, mainly from India and south China. North Asia, that be Manchuria, Siberia, Central Asia and Japan together, received another 50 million. A movement that started in the 1890s with migrants from China, Russia and Korea, and was especially large due to coerced migration from the Soviet Union and Japan in the 1930s. Less is known about exact numbers of the migrations from and within Africa in this period, but Africa experienced a small nett immigration between 1850 and 1950, from a variety of origins.

Transnational labour migration reached a peak of three million migrants per year in the early twentieth century. Italy, Norway, Ireland and the Quongdong region of China were regions with especially high emigration rates during these years. These large migration flows influenced the process of nation state formation in many ways. Immigration restrictions have been developed, as well as diaspora cultures and myths that reflect the importance of migration to the foundation of certain nations, like the American melting pot. The transnational labour migration fell to a lower level from 1930s to the 1960s and then rebounded.

The twentieth century experienced also an increase in migratory flows caused by war and politics. Muslims moved from the Balkan to Turkey, while Christians moved the other way, during the collapse of the Ottoman Empire. 400.000 Jews moved to Palestine in the early twentieth century. The Russian Civil War caused some 3 million Russians, Poles and Germans to migrate out of the Soviet Union. World War II and decolonization also caused migrations, see below.

World War II

See World War II evacuation and expulsion for World War II forced migrations.

The Jewish diaspora across Europe, the Mediterranean and the Middle East formed from voluntary migrations, enslavement, threats of enslavement and pogroms. After the Nazis brought the Holocaust upon Jewish people in the 1940s, there was increased migration to the British Mandate of Palestine, which became the modern day state of Israel as a result of the 1947 UN Partition Plan.

Provisions of the Potsdam Agreement from 1945 signed by victorious Western Allies and the Soviet Union led to one of the largest European migrations, and definitely the largest in the 20th century. It involved the migration and resettlement of close to or over 20 million people. The largest affected group were 16.5 million Germans expelled from Eastern Europe westwards. The second largest group were Poles, millions of whom were expelled westwards from eastern Kresy region and resettled in the so-called Recovered Territories (see Allies decide Polish border in the article on the Oder-Neisse line). Hundreds of thousands of Poles, Ukrainians, Lithuanians, Latvians, Estonians and some Belarusians, were in the meantime expelled eastwards from Europe to the Soviet Union. Finally, many of the several hundred thousand Jews remaining in the Eastern Europe after the Holocaust migrated outside Europe to Israel.

Net migration rates for 2006: positive (blue) and negative (orange)

Target countries with currently high immigration rates are North America, Western Europe, Central Europe, Southern Europe, Australia. Due to refugee movements within Africa, there are African countries with high positive as well as negative migration rates. [2]

Countries of origin with high emigration rates are in Africa, Eastern Europe, Central Asia, South and Central America:

Small countries like island states can have extremely high migration rates that fluctuate over short times due to their low overall population: Micronesia -2% per year, Grenada -1.6%, Samoa -1.2%, Dominica -0.93%, Suriname and Virgin Islands -0.87%, Greenland -0.83%, Guyana and Saint Vincent and the Grenadines -0.75%; Liberia 2.7%, Kuwait 1.6%, Turks and Caicos Islands 1.1%, San Marino 1.1%.

Migrations and climate cycles

The modern field of climate history suggests that the successive waves of Eurasian nomadic movement throughout history have had their origins in climatic cycles, which have expanded or contracted pastureland in Central Asia, especially Mongolia and the Altai. People were displaced from their home ground by other tribes trying to find land that could be grazed by essential flocks, each group pushing the next further to the south and west, into the highlands of Anatolia, the plains of Hungary, into Mesopotamia or southwards, into the rich pastures of China.

Toward an understanding of migration

Types of migrations

  • The cyclic movement which involves commuting, a seasonal movement, and nomadism.
  • The periodic movement which consists of migrant labor, military services, and pastoral farming Transhumance.
  • The migratory movement that moves from the eastern part of the United States to the western part. It also moves from China to southeast Asia, from Europe to North America, and from South America to the middle part of the Americas.
  • Internal migration

Ravenstein's 'laws of migration'

Certain laws of social science have been proposed to describe human migration. The following was a standard list after Ravenstein's proposals during the time frame of 1834 to 1913. The laws are as follows:

  1. Most migrants travel short distances and with increasing distance the numbers of migrants decrease. This law is based upon the assumptions that the higher travel costs and a lack of knowledge of more distant places acts against large volumes of migration.
  2. Migration occurs in stages and with a wave-like motion. Based on his observations in the late nineteenth and twentieth centuries that migration occurred in steps with people gradually moving up the settlement hierarchy - from rural areas to villages, to towns, to cities and finally the capital city.
  3. Migration increases in volume as industries and commerce develop and transport improves, and the major direction of movement is from agricultural areas to centres of industry and commerce.
  4. Most Migrants are adult. Families rarely migrate out of their country of birth.
  5. Women are more migratory than men within their country of birth but men more frequently venture beyond it.
  6. Urban dwellers are less likely to move than their rural counterparts.

Other migration models

Causes of migrations

Causes of migrations have modified over hundreds of years. Some cases are constant, some of them do not carry the same importance as years ago (for example: in 18th and 19th centuries labor migration did not have the same character like today).

In general we can divide factors causing migrations into two groups of factors: Push and pull factors. In general:

  • Push Factors are economic, political, cultural, and environmentally based.
  • Pull Factors are economic, political, cultural, and environmentally based.
  • Barriers/Obstacles which is an example of Nigeria in the 1970s and 1980s.

Some certain factors are both push and pull like education, industry etc.

On the macro level, the causes of migration can be distilled into two main categories: security dimension of migration (natural disasters, conflicts, threats to individual safety, poor political prospects) and economic dimension of migration (poor economic situation, poor situation of national market). [AIV document]

Effects of migration

Migration like any other process shapes many fields of life, having both advantages and disadvantages. Effects of migrations are:

  • changes in population distribution
  • mixing of different cultures and races, which often leads to negative social behaviors – tensions in society between majorities and minorities, followed often by local struggles and racism and racial discrimination. Also criminality growth can be caused. But effects in different societies can be different. It is possible also some positive cultural effects of migration, for example exchange of cultural experience, new knowledge.
  • demographic consequences: since migration is selective of particular age groups, migrants are mostly young and in productive age. It can cause a demographic crisis – population ageing, what in turn can be followed by economic problems (shrinking group of economically active population has to finance extending group of inactive population).
  • economic results, which are of the greatest importance for the development of the countries.

Migration in the European Union

The wages in the European Union are generally higher than the rest of Europe- thus explaining why a large number of Eastern Europeans choose to migrate to the EU. However, such migration is becoming increasingly difficult with the EU's ever more stringent immigration laws. Immigrants from the ten mostly Eastern European states admitted to the EU in 2004, however, can freely migrate to the United Kingdom, Republic of Ireland and Sweden.

Simple English

For the general concept of species moving around, see migration. For people moving data around see data migration.

Human migration means any movement by humans from one locality to another (migration), often over long distances or in large groups. Humans are known to have migrated extensively throughout history and prehistory.

International migration is the movement of people between countries. Some leave their home countries voluntarily and some are forced to leave. They hope to find a job, better climates, access to hospitals, schools and entertainment. Some want to be with friends and relatives but others are forced to leave the country because of religious and political persecution, wars, racial discrimination, famine, or natural disasters. These people are refugees, they move to other countries hoping to find help and asylum. Most refugees are illegal immigrants and more than half are children and women. They live in extreme poverty, lacking food, shelter, clothing, education and medical care.

Rural-urban migration is the movement from country areas to towns and cities. There are many reasons why people leave the countryside. In some areas there is overpopulation, resulting from high birth rates and starvation. Mechanization has caused a reduction in jobs available in the countryside. Farming is hard work with long hours and little pay. In developing countries a lack of money means a lack of machinery. Natural disasters such as droughts, hurricanes, floods and volcanic eruptions destroy villages and crops. There is a lack of services like schools and hospitals in the countryside.

People move to the city because they are looking for better paid jobs and expect to be housed more comfortably and to have a higher quality of life. They have a better chance of services such as schools, medical treatment and entertainment. People are often also attracted by the advantages of a cosmopolitan lifestyle such as shops, restaurants, theatres and nightlife.

Reality is very different. Though as many new arrivals to the city are unlikely to have much money, they will be unable to buy or rent a house, even if one was available. They will probably have to make a temporary shelter using cheap or wasted materials. A lot of migrant workers’ children are also struggling to get a decent education.

In the new country they often are not integrated and are treated like an underclass. But they are needed in the cities even if the local population doesn’t like immigrants because they compete for the same jobs. More people means more traffic and more crime. But in fact they help to build up cities, provide cheap labour, invest money, buy products and services, pay tax and help companies compete. The government should support immigrants because they are very important for the economy of a country.

The movement of populations in modern times has continued under the form of both voluntary migration within one's region, country, or beyond, and involuntary migration (which includes slave trade, Trafficking in human beings and ethnic cleansing). The people who migrate are called migrants, or, more specifically, emigrants, immigrants or settlers, depending on historical setting, circumstance and perspective.
