“…Blau (1994) calls upon scholars of cleavage systems to attend to spatial scale, as sorting processes can lead to different patterns of cross‐cutting and consolidation at different levels of aggregation. Empirical evidence supports these theoretical propositions: consolidated cleavages of various types are associated with political conflict, ineffective public goods provision, greater in‐group identification, stereotyping, and distaste for redistributive policies (Cioraianu, 2020; Desmet et al, 2017; Higashijima & Houle, 2018; Yang, 2003).…”

Like many other wealthy nations, the United States is experiencing substantial population ageing, particularly among Whites, whose median age is over a decade older than Blacks' and Hispanics'. To date, analyses of this demographic divergence have been limited to national and state levels; we know little about its manifestation at smaller scales. This study introduces three micro‐level measures of the joint distribution of age and race, demonstrating that Whites are older than their non‐White neighbours in most integrated neighbourhoods, with notable variation across regional and local characteristics. Racial age gaps significantly predict subsequent declines in neighbourhoods' White population, indicating that racial change has an under‐studied age dimension. Meanwhile, neighbourhoods with relatively younger Whites are rare, clustered in coastal metros, and linked to gentrification. Drawing on theories of multidimensional heterogeneity, I suggest that local consolidation of age and racial differences may undermine stable integration and reinforce inequality.

Simulating collective decision-making and behaviour is at the heart of many agent-based models (ABMs). However, the representation of social context and its influence on an agent's behaviour remains challenging. Here, the Social Identity Approach (SIA) from social psychology, offers a promising explanation, as it describes how people behave while being part of a group, how groups interact and how these interactions and ingroup norms can change over time. SIA is valuable for various application domains while also being challenging to formalise. To address this challenge and enable modellers to learn from existing work, we took stock of ABM formalisations of SIA and present a systematic review of SIA in ABMs. Our results show a diversity of application areas and formalisations of (parts of) SIA without any converging practice towards a default formalisation. Models range from simple to (cognitively) rich, with a group of abstract models in the tradition of opinion dynamics employing SIA to specify group-based social influence. We also found some complex cognitive SIA formalisations incorporating contextual behaviour. When considering the function of SIA in the models, representing collectives, modelling group-based social influence and unpacking contextual behaviour all stood out. Our review was also an inventory of the formalisation challenge attached to using a very promising socialpsychological theory in ABMs, revealing a tendency for reference to domain-specific theories to remain vague.

“…Family members are reliable and trustworthy sources of information, since communication with them is among the most effective. Also, the stronger the emotional bonds, the easier it is to maintain them over long distances [19,37,44,50]. Furthermore, obligations to family members are long-lasting and thus have a significant impact on mobility.…”

Technological and social networks of a pastoralist artificial society: agent-based modeling of mobility patterns

et al. 2021

This paper explores the advantages of simulation to raise the question of how digital and social networks affect the mobility in a pastoralist artificial society in the context of environmental degradation. We aim to explore mechanisms and develop scenarios, which are going to be validated through further research. We use a model of a simple pastoralist society in a world without borders to migration by adding the possibility of experiencing the effects of social structures (such as family and friends) and technological networks (e.g., social media). It appears obvious that pastoralist mobility depends on other dimensions as land tenure and traditional knowledge; however, isolating these two effects and experimenting in a simple society allow us to filter the multidimensionality of mobility decisions and concentrate on comparing scenarios in several different social structures and technological network combinations. The results show an expected behavior of more connection and more mobility, and a non-linear emergent behavior where pastoralists wait for a longer amount of time to mobilize when they interact using powerful social and technological networks. This occurs until they decide to move, and then, they mobilize more quickly and strongly than they did when communication was non-existent between them. The literature on migration explains this emergent non-linear behavior.
