With the increasing interest in large-scale social network analysis, recent research has expanded into nation-wide networks generated from administrative data. We construct a multilayer population-scale social network for Sweden using public register data from 2000 to 2017, covering approximately 8.3 million individuals aged 15 and older. The network models the social opportunity structure in Sweden across six layers: close family, extended family, household, school, neighbors, and work. We analyze the structure and connectivity patterns in the network, comparing our findings to a similar study of the Netherlands. The comparison reveals broadly similar degree distributions and small-world characteristics, but also discrepancies likely driven by differences in population density.
期刊介绍：
We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections.
Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021).
•Engineering
Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live.
•Physical sciences
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
•Earth and environmental sciences
Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems.
•Biological sciences
Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants.
