Step Migration
Step migration is a migration pattern conceptualized in 1885 by Ernst Georg Ravenstein, who observed migration as occurring stage by stage as rural inhabitants move closer to urban areas of growth. It is a migration pattern regarded by some scholars to be a widely popular form of international migration in the twenty-first century globalized world. There is a large breadth of study proving the existence of step migration in many international migration patterns, although there is lack of consensus over its exact specification and measurement. Step migration scholars deem it to be an important international trend that has the power to aid in the design of policy development efforts in both rural and urban areas worldwide. According to Abrahm Lustgarten, Senior Environmental Reporter for ProPublica, in his May 2021 report, Step migration – or "stepwise migration" – is a characteristic pattern of migration driven by climate change.

The European Union (EU) has expanded a number of times throughout its history by way of the accession of new member state of the European Union, member states to the Union. To join the EU, a state needs to fulfil economic and political conditions called the Copenhagen criteria (named after the Copenhagen summit in June 1993), which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the Maastricht Treaty, each current member state and the European Parliament must agree to any enlargement. The process of enlargement is sometimes referred to as European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws. The EU's predecessor, the European Economic Community, was founded with the Inner Six member states in 1958, when the Treaty of Rome came into force. Since then, the ...

Demography
Demography () is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the interplay of fertility (births), mortality (deaths), and migration. Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population. Demographic analysis estima ...

Genetic Genealogy
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as Surname DNA project, surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project. about 30 million people had been tested. As the field developed, the aims of practitioners broadened, with many seeking knowledge of their ancestry beyond the recent centuries, for which traditional pedigrees can be constructed. History The investigation of surnames in genetics Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. ...

Human Overpopulation
Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustainability, sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities. Since 1804, the global living human population has World population milestones, increased from 1 billion to 8 billion due to Modern medicine, medical advancements and improved agricultural productivity. Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. According to the most recent Projections of population growth, United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide. Other models agree that the population will stabilize before or after 2100. Conversely, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demographic Economics
Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics. Aspects Aspects of the subject include: * marriage and fertility * the family * divorce * morbidity and life expectancy/mortality * dependency ratios * migration * population growth * population size * public policy * the demographic transition from " population explosion" to (dynamic) stability or decline. Other subfields include measuring value of life and the economics of the elderly and the handicapped and of gender, race, minorities, and non-labor discrimination. In coverage and subfields, it complements labor economics and implicates a variety of other economics subjects.

Chinese Emigration
Waves of Chinese emigration have happened throughout history. They include the emigration to Southeast Asia beginning from the 10th century during the Tang dynasty, to the Americas during the 19th century, particularly during the California gold rush in the mid-1800s; general emigration initially around the early to mid 20th century which was mainly caused by corruption, starvation, and war due to the Warlord Era, the Second Sino-Japanese War and the Chinese Civil War; and finally elective emigration to various countries. Most emigrants were peasants and manual laborers, although there were also educated individuals who brought their various expertises to their new destinations.
