The spatial structure of transnational human activity

Abstract: Recent studies have shown that the spatial structures of animal displacements and local-scale human motion follow Lévy flights. Whether transnational human activity (THA) also exhibits such a pattern has however not been thoroughly examined as yet. To fill this gap, this article examines the planet-scale spatial structure of THA (a) across eight types of mobility and communication and (b) in its development over time. Combining data from various sources, it is shown that the spatial structure of THA can indeed… Show more

“…The vast majority of ties in Patterns II and III is thus interregional, which holds only for a minority of ties in Pattern I. This confirms our classification and fits the idea that most mass tourism occur over short distances [61,62], whereas individual tourism and the market for cheap labor migrants are globalized. Figure 11 shows the mobility ties between country pairs with the largest seasonal components, ordered by world region (denoted by different colors).…”

“…In fact, in contrast with the Gaussian cases, Lévy flights are characterized by frequent movement for short distances, interrupted by random changes of direction that are only occasionally followed by movements over longer distances. Sorting out the displacement lengths covered in these journeys by size frequency, results in a distribution with a long tail that obeys a power law [79]. This pattern, for instance, has been found in the displacement of animals [80, 81], and humans in local [82], nation-wide [57] and global sphere [79].…”

“…Sorting out the displacement lengths covered in these journeys by size frequency, results in a distribution with a long tail that obeys a power law [79]. This pattern, for instance, has been found in the displacement of animals [80, 81], and humans in local [82], nation-wide [57] and global sphere [79]. Thus, the model under consideration here is written as a generalized Edwards-Wilkinson equation: where y ( r , t ) represents the average incidence rate in a municipality localized by the position of vector r in relation to another municipality forming a pair, ν is a diffusion constant, η ( r , t ) is a random noise with zero mean and finite variance uncorrelated in space and time.…”

“…national diffusion, as Tarde would expect. We use the aforementioned data on the prevalence of Facebook friendships between individual country pairs in 2012 (Deutschmann 2016). Note that this is but one channel of person-toperson influence, which could also occur through phone calls, personal travel, e-mail, and so on, none of which are measured here.…”
