### Contemporary Types of Migration

Because of emerging global forces of all kinds—social, economic, environmental, and political—there has been a recent rise in migration within geographical regions and across countries. Four of the most common types of contemporary migration are listed below. Each derives from different causes and is associated with different push and pull factors (Woldeab 2019). In some situations, these types of migration may overlap, such as in the aftermath of a natural disaster.
1. Labor migration is the movement of people for the purpose of employment and/or economic stability. It may be an internal migration from one town to another within the same country of origin, or it may involve travel across countries in search of opportunities. In 2017, the United Nations International Labour Organization estimated that there were 164 million labor migrants worldwide (Global Migration Data Analysis Centre 2021).
2. Forced migration or displacement, also called involuntary migration, is migration due to persecution, conflict, or violence and involves refugees and those seeking asylum. The UN Refugee Agency (UNHCR) estimated that as of the end of 2019, there were some 79.5 million forced migrants or displaced persons worldwide. More than two-thirds (68 percent) of those displaced persons came from just five countries: Syria, Venezuela, Afghanistan, South Sudan, and Myanmar (UNHCR 2020). One out of every 108 people was displaced in 2018 (UNHCR 2019).
3. Forced labor, human trafficking, and modern slavery are a set of linked terms defined as the recruitment, transportation, transfer, and/or harboring of persons by means of threat or use of force or coercion for the purpose of exploitation (UN 2020). This includes sexual slavery and forced labor. As of 2016, some 25 million people were involved in forced labor and some 40.3 million in modern slavery worldwide, while an estimated 15.4 million were in forced marriages (https://www.ilo.org/global/topics/forced-labour/lang--en/index.htm). While a large proportion of the victims are women, human trafficking involves men and children as well. The Counter Trafficking Data Collaborative (https://www.ctdatacollaborative.org/) estimates that nearly 80 percent of international human trafficking journeys pass through airports and other official border control points.
4. Environmental migration is displacement caused by natural disasters, such as earthquakes, hurricanes, or droughts. It can be permanent or temporary and is a rapidly growing area of migration due to global climate change. In 2018, 17.2 million people were displaced due to environmental conditions; by 2019, the number had risen to 24.9 million (https://www.internal-displacement.org/global-report/grid2019/).
Anthropologists who study migration are often involved in multi-sited ethnographic research, exploring not only migrant populations but their communities of origin as well. Understanding the social and cultural attributes of communities of origin helps researchers gauge the level and types of adaptation caused by migration. Also, communities of origin typically remain part of migrants’ wider social networks and are vital to their well-being and success. It is not uncommon for relatives and other members of the migrants’ home communities to follow them to their new settlements and reestablish a sense of community and a set of self-help networks there. This process of serial migration from the same community of origin is known as chain migration.

### Labor Migration and Migrant Routes

While migration, in its widest sense, is any movement that reestablishes a household, many migratory patterns are specifically associated with socioeconomic need, mainly shifting employment opportunities. Labor migration can be permanent or circular. Circular migration is a repeated pattern of movement between locations, usually mapped to the availability of work. One type of circular migration is seasonal migration, which is migratory movement that coincides with seasonal labor needs, such as planting, harvesting, service, and construction work. Some seasonal workers migrate, with or without their families, for temporary, often low-paid work. Other seasonal workers have long-term relationships with their employers and legal work permits (also called Employment Authorization Documents, or EADs, in the United States) and will return to the same work sites year after year, sometimes maintaining a joint household with other families at the work site. These individuals will often maintain a family household in their country of origin and send home remittances, or transfers of money from workers to their home countries, usually for their families. Today, one in nine people worldwide depends on remittances from migrants (Global Migration Data Analysis Centre 2021).
Many people migrate in search of work and a better life without legal permits or assurance of employment. The migration journey made in search of opportunities can be filled with dangers, hardships, and even death. Some regions of the world have well-established migrant trails, which are the routes of most worldwide migration. The most congested migration routes are:
1. the eastern Mediterranean route, with a flow of migrants from the Middle East and North Africa to Europe, crossing through Turkey;
2. the Mediterranean Sea route, with migration from the Middle East and North Africa to Europe, across the Mediterranean Sea;
3. the Southeast Asian route, with migrants primarily moving southward from the Asian mainland into Indonesia and Malaysia; and
4. the Central American route, which brings migrants from South and Central America into North America.
These migrant trails have a huge impact on the social, political, and economic life of all of the countries that are a part of the route, bringing both benefits and challenges. Those in the United States are most familiar with the Central American route, which begins as far south as South America and extends as far north as Canada. The most contested part of the “trail,” however, is the portion along the Rio Grande, the river that separates Mexico and the United States.
In his remarkable four-field study of undocumented migrants entering the United States across the border with Mexico, The Land of Open Graves (2015), Chicano anthropologist Jason De León reveals a less visible side of undocumented migration. He describes a type of cat-and-mouse game between migrants and those attempting to stop them, resulting in widespread suffering and high human and financial costs. De León conducted a multi-sited ethnography, doing research in various locations in both Mexico and the United States and consulting various groups along the migration route, including illegal migrants and border patrol agents as well as smuggling groups and drug traffickers.
Since 1994, the US Border Patrol has had a policy of “prevention through deterrence” that attempts to prevent undocumented migrants from reaching the U.S. border. Legal international entryways in cities such as Tucson, Arizona, and El Paso, Texas, were heavily fortified with fencing and additional patrol agents to make undocumented crossing exceptionally difficult. As a result, migrant entry points shifted away from urban areas and into more hostile terrain, such as the Sonoran Desert region of Arizona. While this has not significantly lowered the frequency of these crossings, it has made the journey much more dangerous and far less visible to residential populations and humanitarian groups. In addition to the threat of harsh and rugged landscapes, there are the dangers of extreme weather, dehydration, bandits, and even wild animals. De León concludes, “The Border Patrol has intentionally set the stage so that other actants [agents of deterrence] can do most of the brutal work” (61).
During his study, De León and his team located the body of Maricela Zhagüi Puyas, a woman originally from Cuenca, Ecuador. She had left her family, including her children, in Ecuador in order to seek employment in the United States, hoping to send money home to them. She was in debt for more than $10,000, most of it to the trail guide (called a ) who was supposed to guide her on her journey. Such trail guides often extort large sums of money from vulnerable migrants and then leave them to make their way alone. Maricela had made a journey of more than 5,000 miles from Cuenca, Ecuador, all the way to the Sonoran Desert in Arizona, when she died of exhaustion and exposure, technically having reached the United States. In the 14-year period between 2000 and 2014, 2,721 migrants were found dead in Arizona’s Sonoran Desert, approximately 800 of whom remain unidentified today. In 2020, there were an estimated 227 migrant deaths in the Sonoran graveyard, making it the deadliest year on record for that corridor trail (Snow 2021). De León’s work continues today through a series of pop-up exhibitions and workshops entitled .
This humanitarian crisis is far from being resolved. In 2020, 400,651 undocumented migrants were apprehended and expelled by the U.S. Border Patrol (U.S. Customs and Border Protection 2020). Immigrants, both documented and undocumented, make up a majority of the farmworkers and meatpacking workforce in the United States today. Once employed, these immigrants, who are frequently separated from their families, face hazardous working conditions, language barriers, long hours, low pay, and substandard housing. Because of their legal status, many also struggle with inadequate access to health care and rising discrimination.
Biocultural anthropologist Shedra Snipes and her team (Snipes et al. 2007) conducted focus group interviews among 69 male and female Mexican immigrant farmworkers in the Yakima Valley of Washington State. They were particularly interested in the ways the farmworkers defined and experienced stress. Their interviewees distinguished between physical and mental stressors and cited the most common causes of stress as work, personal illness, lack of work, family illness, and family stress. Snipes et al. noted that many stressors were linked by a common theme of inconsistent work and the injusticia (injustice and unfairness) of low pay and poor working conditions. One farmworker noted, “Sometimes there are many people wanting to work in the field. You complain about something like not having water, or the bathrooms being dirty, [and] they tell you right away, ‘If you don’t like it go find a job somewhere else’” (366). Another common theme was the stress of living in a different culture. Several farmworkers commented that cultural differences, such as language barriers, communication from schools regarding their children, or complaints from neighbors when they had rowdy family get-togethers, contributed to their experience of stress. As this example shows, at the intersection of culture and migration, many factors affect an individual’s ability to adapt to new living conditions.

### Refugees Beyond the Nation-State

Refugees are persons who are forced to cross international boundaries to seek residence. Pushed out of their countries, most commonly because of war, famine, or persecution, they typically arrive under extreme circumstances with little food, clothing, or material possessions. They are frequently separated from their relatives and have little chance of finding employment or reestablishing their household. Because of their status as stateless persons (persons forced to leave their countries) and their inability to procure proper travel documentation, refugees are protected under the 1951 United Nations Refugee Convention, which derives from Article 14 of the Universal Declaration of Human Rights, passed in1948. The Universal Declaration of Human Rights establishes an international legal right for people to seek asylum, which is legal protection extended by one country to citizens of another. The United Nations High Commissioner for Refugees heads the UN Refugee Agency, a global organization that directs troops and aid workers to set up refugee camps and organizes international efforts to ease the suffering of refugees.
In her ethnographic study of Congolese refugees in the Ugandan capital city of Kampala, cultural anthropologist Georgina Ramsay (2016) focuses on the ways in which refugees protect themselves, both physically and psychologically, by what they call “avoiding poison.” In 2012, there were approximately 50,000 refugees living in Kampala as a result of ongoing political instability, warfare, and corruption in the Democratic Republic of the Congo. Housed initially in a refugee settlement away from urban areas, the group of refugees interviewed by Ramsay opted to move to Kampala for greater opportunities and more security, as the refugee settlements were troubled by crime and violence. As one informant told Ramsay, “There are bad people everywhere in the camp” (115). The government of the Democratic Republic of the Congo allowed resettlement in Kampala if the refugees procured a legal permit and a way to make a living independent of government funding or humanitarian aid. Given their displacement from their own ethnic communities and social networks, refugees faced unreliable social communities, in which their relationships were recently formed, as well as fear and the looming threat of having to return to the settlements if they lost their jobs or housing arrangements. Many either relied on or supplemented their wages with remittances from relatives living elsewhere in an effort to create greater security in the urban environment.
The “poison” feared by this group of refugees is a symbolic agent administered by “unknown assailants” (113), most often sprinkled into the food they prepare, and capable of making them sick both physically and psychologically. The administering of this poison is not always intended as a personal attack; rather, the refugees believe that their day-to-day life outside of their cultural homelands makes them vulnerable. They believe that they are most vulnerable during cooking and eating. In their home communities, cooking and eating were normally times of social interaction and sharing, but cooking and eating are now highly privatized acts for them. Families eat only with each other, within their own homes, and do not accept any shared food, even when they are hungry. The result is an intentional physical distancing from each other and a strengthening of family-only social bonds. While this approach clearly weakens the refugees’ ability to build a large and sustainable self-help community in Kampala, it does afford them a sense of positive control (agency) over their day-to-day lives. This sense of social agency over the threat of “poison,” giving the refugees an ability to control some aspects of their day-to-day lives, is an example of the adaptive nature of culture under very challenging circumstances.

### Pandemic as a Global Migration

People and goods are not the only things that migrate. Along with human migration, there is a host of secondary movements that can affect the human population globally. Diseases are a prime example. Diseases that may have once been contained in a single region can move, along with their human and animal hosts, into new geographic areas, where they can become even more virulent. When diseases spread more than expected among a given group of people, they are referred to as epidemics. An outbreak of a disease over a very broad area, typically crossing international boundaries, is called a pandemic. Some early pandemics in Europe were the plague of Athens in 430 BCE (possibly typhus or typhoid fever or Ebola), the Antonine plague from 165 to 180 CE (possibly smallpox), and the Black Death from 1347 to 1351 (caused by a bacterium carried by fleas and infected rodents). In the Americas, Mexico and Central America suffered from various documented pandemics, starting with the arrival of the Spanish in Mexico in 1519, which set off a widespread smallpox outbreak that extended into South America. There have been other pandemics, including the cocoliztli epidemic from 1545 to 1548, likely a form of enteric fever, and the so-called Spanish flu, first detected in the United States in 1918 (Alchon 2003; Vågene et al. 2018). The most serious recent pandemic in the United Stated had been the swine flu pandemic of 2009–2010 ... until 2019–2020.
In the last few months of 2019, the viral coronavirus SARS-CoV-2, known as COVID-19, began a global migration from Wuhan, Hubei Province, China, to every continent of the world. Carried between geographically distant locations by human hosts traveling for all sorts of reasons—including work, study, tourism, visitation, and displacement—as well as within towns and communities by people shopping, attending religious services and schools, or even visiting friends and families, COVID-19 quickly became a global emergency. First reported to the World Health Organization (WHO) on December 31, 2019, COVID-19 was officially declared a global pandemic on March 11, 2020. Throughout 2020, the disease continued to spread rapidly, overwhelming medical facilities, ravaging countries’ economies, and forcing people to alter the structures of most social institutions, including schools, churches, weddings, and even funerals. By October 2021, some 248 million people had been infected, including several world leaders, and more than 5 million people had died from the disease.
The COVID-19 virus spreads through airborne transmission when someone inhales droplets expelled by an infected person coughing, sneezing, or even exhaling. As with measles and tuberculosis, the only fully effective form of containment outside of a vaccine and the development of antibodies is quarantine. When the WHO declared COVID-19 a global pandemic, the most important advice was to limit all unnecessary movements and gatherings, wear masks, and practice physical distancing. But given the global nature of our lives today, it was very difficult to halt either the movement of people or the spread of the disease. On January 20, 2020, the first reported case in the United States was diagnosed in Washington State, in a man in his thirties who had just returned from Wuhan. By that point, the virus had already spread to Taiwan, Japan, Thailand, and South Korea. On January 24, the first European cases were reported in France. The disease continued to quickly spread all over the world, including on international transport, such as cruise and cargo ships. In December 2020, there were several cases reported in Antarctica. Only 14 countries reported no COVID-19 cases as of April 2021, all except two of them island nations or territories in the Pacific and Atlantic Oceans with strict travel policies: Tuvalu, Tonga, Tokelau, St. Helena, the Pitcairn Islands, Palau, Niue, Nauru, Kiribati, the Federated States of Micronesia, the Cook Islands, and American Samoa. (The two non-island nations, North Korea and Turkmenistan, are believed to have unreliable data.) As a result of migration, the disease transformed peoples’ lives everywhere.
But migration can also bring relief from pandemics. The same conveyances that led to the initial spread of the disease have also brought relief workers, food, medical supplies, and life-saving vaccines to communities worldwide. In addition, scientists and researchers worked tirelessly in multinational efforts to sequence the COVID-19 genome so that vaccine development could proceed rapidly. Globally, several countries developed lifesaving vaccines and began working together to disperse them to communities in need. As our world becomes increasingly interdependent, it is critical that we understand the important role of migration in so many aspects of our survival.

### Summary

Migration is an important characteristic of human behavior. People migrate for all sorts of reasons, moving from place to place in search of economic opportunities, refuge from political or social oppression, educational opportunities, health resources, fulfillment of family needs, or simply the pleasure of travel itself. From our earliest ancestral beginnings, humans have moved from place to place, sometimes on a seasonal basis and sometimes permanently.
The earliest hominins migrated within and out of Africa, settling parts of Europe, Asia, and eventually Australia, adapting to their new environments and diversifying biologically as a species. The last major continental settlement was North and South America. Archaeological evidence shows early human occupations in the Americas as early as 20,000 years before present. These humans may have arrived by several possible routes, including across the Bering land bridge and along the Pacific coastline of North and South America.
Historically, global forces have also contributed to migration, including seafaring explorations, colonialism, and the transatlantic slave trade that led to a diaspora (dispersal) of millions of African peoples into the Western Hemisphere. Today, many of these historical forces continue to impact our lives as migrants seek opportunities and better, safer lives. Finance, media, and ideologies increasingly entangle the global world today.
Anthropological research has shown the reach of globalization into small communities where peasants and Indigenous peoples, once mistakenly thought to be simple rural farmers or subsistence producers, negotiate the market value of their labor and products, sometimes against large countries or corporations and often facing unfairness and injustice. This disparity typically leads to internal migration from rural areas into urban zones. As with any form of migration, culture change and adaptation have always been a part of the migrant experience.
Because of emerging global forces of all kinds, there has been a rise in voluntary and involuntary migration within geographical regions and across countries, leading to inequality along the margins. Contemporary migrations include labor migration, forced migration or displacement, forced labor, human trafficking or modern slavery, and environmental migration, typically caused by global climate change. There are numerous well-trod migrant routes worldwide connecting countries in both formal and informal ways. One of the most violent routes is the Central American route, which connects South America, Central America, and Mexico to the United States. Refugees are among those in greatest need of humanitarian aid today.
People and goods are not the only things that migrate. Along with human migration, there are secondary movements that can affect the human population globally. Diseases move along with people. Historically, there have been many epidemics within populations and pandemics across regions and countries. In 2019, COVID-19 began migrating globally, eventually affecting every country and causing deaths, chronic illnesses, and economic devastation. As our world becomes increasingly interdependent, it is critical that we understand the important role of migration in so many aspects of our survival.
