Human capital flight is the emigration or immigration of individuals who have received advanced training in their home country. The net benefits of human capital flight for the receiving country are sometimes referred to as a "brain gain" whereas the net costs for the sending country are sometimes referred to as a "brain drain". In occupations with a surplus of graduates, immigration of foreign-trained professionals can aggravate the underemployment of domestic graduates, whereas emigration from an area with a surplus of trained people leads to better opportunities for those remaining. But emigration may cause problems for the home country if the trained people are in short supply there.
Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location. The movement often occurs over long distances and from one country to another, but internal migration is the dominant form of human migration globally.
Free migration or open immigration is the position that people should be able to migrate to whatever country they choose with few restrictions.
A remittance is a non-commercial transfer of money by a foreign worker, a member of a diaspora community, or a citizen with familial ties abroad, for household income in their home country or homeland.
Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.
African immigrants in Europe are individuals residing in Europe who were born in Africa. This includes both individuals born in North Africa and Sub-Saharan Africa.
Opposition to immigration, also known as anti-immigration, is a political position that seeks to restrict immigration. In the modern sense, immigration refers to the entry of people from one state or territory into another state or territory in which they are not citizens. Illegal immigration occurs when people immigrate to a country without having official permission to do so. Opposition to immigration ranges from calls for various immigration reforms, to proposals to completely restrict immigration, to calls for repatriation of existing immigrants.
Codevelopment is a trend of thought and a development strategy in development studies which considers migrants to be a developing factor for their countries of origin.
Circular migration or repeat migration is the temporary and usually repetitive movement of a migrant worker between home and host areas, typically for the purpose of employment. It represents an established pattern of population mobility, whether cross-country or rural-urban. There are several benefits associated with this migration pattern, including gains in financial capital, human capital, and social capital. There are also costs associated with circular migration, such as brain drain, poor working conditions, forced labor, and the inability to transfer acquired skills to home economies. Socially, there are strong connections to gender, health outcomes, development, poverty, and global immigration policy.
An open border is a border that enables free movement of people between jurisdictions with no restrictions on movement and is lacking substantive border control. A border may be an open border due to intentional legislation allowing free movement of people across the border, or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border. An example of the former is the Schengen Agreement between most members of the European Economic Area. An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services, and only to borders between political jurisdictions, not to mere boundaries of privately owned property.
During the period of 1965 – 2021, an estimated 440,000 people per year emigrated from Africa; a total number of 17 million migrants within Africa was estimated for 2005. The figure of 0.44 million African emigrants per year pales in comparison to the annual population growth of about 2.6%, indicating that only about 2% of Africa's population growth is compensated for by emigration.
Michael Andrew Clemens is an American economist who studies international migration and global economic development.
Women migrant workers from developing countries engage in paid employment in countries where they are not citizens. While women have traditionally been considered companions to their husbands in the migratory process, most adult migrant women today are employed in their own right. In 2017, of the 168 million migrant workers, over 68 million were women. The increase in proportion of women migrant workers since the early twentieth century is often referred to as the "feminization of migration".

Almost half of international migrants are women, generally travelling as either migrant workers or refugees. Women migrant workers migrate from developing countries to high-income countries to engage in paid employment, typically in gendered professions such as domestic work. Because their work disproportionately takes place in private homes, they are vulnerable to exploitation and abuse. Wages earned are largely sent home to the originating country to support the cost of living of the family left behind.
