New World Orders: Continuities and Changes in Latin American Migration
The Annals of the American Academy of Political and Social Science
|September 4, 2010
Summary
Latin American migration has diversified beyond the United States, with increased outflows to Europe, Canada, Australia, Japan, and within the region itself over the past 30 years.
Area of Science:
- Demography
- Sociology
- International Relations
Background:
- Historically, Mexico has been the primary source of Latin American migrants to the U.S.
- Recent decades show a significant rise in emigration across Latin America.
- International migration is now a key demographic factor in the region.
Purpose of the Study:
- To outline trends in volume and composition of migrant outflows from Latin America.
- To highlight the diversity of these migration streams.
- To analyze the broadening destinations and characteristics of migrants.
Main Methods:
- Review of existing literature and data on international migration from Latin America.
- Analysis of trends in migrant volume, composition, and destinations.
- Examination of legal entry, demographics (gender, class, race, ethnicity), and societal integration.
Main Results:
- Emigration has become a major demographic trend in Latin America over the last 30 years.
- Migration patterns are increasingly diverse, with multiple destinations beyond the U.S.
- Migrant outflows show variety in legal status, gender, class, and ethnic origins.
Conclusions:
- Latin American migration is no longer a unidirectional flow to the United States.
- New migration streams are established towards Europe, Canada, Australia, Japan, and intra-regionally.
- The complexity of migration necessitates understanding diverse origins, destinations, and integration patterns.

Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
Gene Flow
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
The Colonization of Land
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...
Ethnic Identity within a Larger Culture
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...
