Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant emigrates from their old country, and immigrates to their new country. Thus, both emigration and immigration describe migration, but from different countries' perspectives.
Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and seeking asylum to get refugee status in a foreign country, may lead to permanent emigration.
Forced displacement refers to groups that are forced to abandon their native country, such as by enforced population transfer or the threat of ethnic cleansing. Refugees and asylum seekers in this sense are the most marginalized extreme cases of migration, facing multiple hurdles in their journey and efforts to integrate into the new settings. Scholars in this sense have called for cross-sector engagement from businesses, non-governmental organizations, educational institutions, and other stakeholders within the receiving communities.
Patterns of emigration have been shaped by numerous economic, social, and political changes throughout the world in the last few hundred years. For instance, millions of individuals fled poverty, violence, and political turmoil in Europe to settle in the Americas and Oceania during the 18th, 19th, and 20th centuries. Likewise, millions left South China in the Chinese diaspora during the 19th and early 20th centuries.
push and pull factors
Demographers distinguish factors at the origin that push people out, versus those at the destination that pull them in.

La fuite des cerveaux (terminologie en sociologie), exode des cerveaux (Québec) ou fuite du capital humain (terminologie en économie), désigne de façon populaire les flux migratoires de scientifiques, de chercheurs ou plus généralement de personnes à haut niveau de qualification qui s'installent à l'étranger pour trouver de meilleures conditions de vie, d'études, de travail ou de rémunérations. Dans les estimations statistiques, on se réfère plutôt au taux d'émigrants parmi les personnes ayant au moins deux années d'éducation supérieure.
