Summary
Internal migration has decreased in developed nations. However, in Norway, increased migration resulted from a more educated populace and evolving household structures, challenging existing theories.
Area of Science:
- Demography
- Sociology
- Human Geography
Background:
- Internal migration has declined in high-income countries like Australia, the UK, and the US.
- Explanations include societal development, changing values, and demographic shifts.
Purpose of the Study:
- To evaluate macro-level explanations for declining internal migration in Norway.
- To empirically test theories using Norwegian population data.
Main Methods:
- Utilized full-population register data from 1981-2015.
- Employed Oaxaca-Blinder analysis to decompose migration changes.
Main Results:
- Changes in population composition and behavior have increased migration in Norway.
- Increased education and altered household structures boosted migration, outweighing population aging effects.
Conclusions:
- Macro-level theories of migration decline may not be universally applicable.
- Further conceptual and empirical research is needed to understand migration dynamics.

7.9K
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.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

23
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.
