Since knowledge about patterns of elderly people in cities is limited, this paper formulates steps for the initialisation of an agent-based model, combined with different data sources. The first step is to identify different types of elderly people using cluster analysis, and then the clusters are expanded into agent typologies with behaviour rules, which form the basis for an artificial population. The clusters are derived based on survey data and then analysed and modified using insights from census data and expert interviews. The agents' relocation behaviour is estimated based on literature research, expert interviews and a survey. The spatial information of the agents is added with a spatial microsimulation. The resulting artificial population presents the real population well and can be used in an empirically based data-driven agent-based model.

However, there is a lack of research on modelling the combination of an ageing population and the impact of super-diversity on it. Progress on this subject might have a huge impact on urban development, since those factors influence the spatial distribution of the (ageing) population. We therefore study data sets on the example of Berlin, and analyse them with statistical methods towards those factors. The aim of the analysis is the division of the population into groups, which will be the foundation for agents, states and transition rules in the modelling process which will be done with ABM and/or CA. Some examples and division possibilities will be given as well as a discussion of challenges for future research directions.

However, the intersection between superdiversity and ageing has been largely absent from the literature, despite its importance for urban and social planning. Agent-Based Modelling (ABM) comprises a commonly used method to simulate and analyse urban development in the context of demographic change, but suffers from high sensitivity to parameterisation. We therefore propose a mixed-methods approach to developing agents for the purpose of ABM, using hierarchical cluster analysis, expert interviews, and focus groups. The quantitative and qualitative results are compared and contrasted to derive empirical agents. A geospatial dataset is then used to explore the feasibility of assigning multimethod-derived agents to a ‘home location’. Our statistical results exhibited a high level of agreement with the qualitative analysis, while the derivation of agent locations presented some unique methodologica...

Given that the range of action usually decreases in later life, the living environment around the place of residence plays an important role in the social integration of the older generation. Hence, spatial patterns of residence indicate the extent of opportunities for the older population to engage in urban life and, therefore, need to be addressed by urban planning and policy. The aim of this article is to study the interrelation between diversity in later life—in terms of migrant history, gender, social class, and age—as well as planned and actual (past) movements of elders. We have chosen Berlin as a case study and draw from a quantitative survey with elders (age 60+) from diverse backgrounds (N = 427). Our results from descriptive analysis and statistical hypothesis tests show that age impacts people’s past and planned movement; we observe a peak in the decisions ...

We conclude by asserting the utility of mixed-methods for deriving agents to be used in population modelling.

We have chosen Berlin as a case study and draw from a quantitative survey with elders (age 60+) from diverse backgrounds (N = 427). Our results from descriptive analysis and statistical hypothesis tests show that age impacts people's past and planned movement; we observe a peak in the decisions to move at the age of 65-75 and a drop in the inclination to move among people over 80. None of the other factors is similarly influential, but we observe appreciable tendencies regarding the impact of gender and social class on planned movements. Our study suggests that variables other than classic socio-demographic data, such as apartment size, rent, social networks, and health, and their interrelations may offer a promising starting point for achieving a full picture of older people's movement behaviour.
