“…The number of mobile individuals between two locations determines the edge weight. Examples of empirical analyses of such mobility networks include individuals' change in occupation over the life-course (Toubøl and Larsen, 2017;Cheng and Park, 2020), inter-generational mobility between social classes (Melamed, 2015), migration patterns between countries (Windzio, 2018), residential moves between neighbourhoods (Müller et al, 2018), patients transfers between hospitals (Stadtfeld et al, 2016), hiring of graduates between universities (Clauset et al, 2015;Gondal, 2018), and mobility of government officials between branches (Woldense, 2018). 1 The varying mobility issues outlined above are treated as network questions for one of two broad reasons-first, to explore the data with descriptive networks analyses, or, second, to uncover dependence structures in these mobility networks with statistical network models.…”
