Probabilistic projections of distributions of kin over the life course Open
BACKGROUND Mathematical kinship demography is an expanding area of research. Recent papers have explored the expected number of kin a typical individual should experience. Despite the uncertainty of the future number and distributions of k…

A mathematical framework for time-variant multi-state kinship modelling Open
Recent research on kinship modelling in demography has extended age-structured models (i) to include additional characteristics, or "stages" (multi-state kinship), and (ii) to time-variant situations. A wide variety of population structure…

Mixed-frequency VAR: a new approach to forecasting migration in Europe using macroeconomic data Open
Forecasting international migration is a challenge that, despite its political and policy salience, has seen a limited success so far. In this proof-of-concept paper, we employ a range of macroeconomic data to represent different drivers o…

Investigating immersion and migration decisions for agent-based modelling: A cautionary tale Open
Background Agent-based modelling provides an appealing methodological choice for simulating human behaviour and decisions. The currently dominant approaches based on static transition rates or unverified assumptions are restrictive, and co…

Mapping secondary data gaps for social simulation modelling: A case study of the journeys of Syrian asylum seekers to Europe Open
Simulation models of social processes may require data that are not readily available, have low accuracy, are incomplete or biased. The paper presents a formal process for collating, assessing, selecting, and using secondary data as part o…

Simulation studies of social systems: telling the story based on provenance patterns Open
Social simulation studies are complex. They typically combine various data sources and hypotheses about the system’s mechanisms that are integrated by intertwined processes of model building, simulation experiment execution and analysis. V…

European migration governance in the context of uncertainty Open
Migration inherently embodies uncertainty and dynamism, eluding precise conceptualization, definition and measurement. Embedded within intricate migration driver environments and shaped by the diverse agency of actors involved—prospective …

Assessing Timely Migration Trends Through Digital Traces: A Case Study of the UK Before Brexit Open
Digital trace data presents an opportunity for promptly monitoring shifts in migrant populations. This contribution aims to determine whether the number of European migrants in the United Kingdom (UK) declined between March 2019 and March …

Exploring the Potential of Using a Text-Based Game to Inform Simulation Models of Risky Migration Decisions Open
Background In this paper, we explore the potential of games to collect empirical data for informing agent-based simulation models of migration. To examine the usefulness of game-based approaches, we conducted a simple, yet carefully design…

A Fast Embedded Language for Continuous-Time Agent-Based Simulation Open
In agent-based simulation methods and applications, discrete timestep approaches prevail. To support continuous-time agent-based simulation, we analyze how methods for simulating population-based Con-tinu-ous-Time Markov Chains (CMTCs) can…
