Social contacts are a key element when modeling the spread of epidemics. Classic top-down approaches like ODEs do not consider the social system explicitly because they use abstract parameters that are representing a combination of various real values. By contrast, agent based models provide a more detailed structure and directly use real world values instead of abstract ones. In this paper we first introduce a basic concept of a simple contact system in an agent based SIR model. Such a model corresponds with known top-down approaches very well. Then we propose a method to extend the basic approach with households. Therefore we make use of detailed data that is provided by Statistics Austria. In a validation process we see that, under special presumptions, the household extension is still comparable with the basic approach. This is important because knowledge about behavior of SIR epidemics still has to apply on the extended model. In contrast to the basic model it is now possible so simulate a wide range of new scenarios. Another strength is the ability for more detailed evaluation of simulation runs. In a sample scenario we show the impact of different household sizes on the spread
of an SIR epidemic. Furthermore we give ideas for more detailed and complex scenarios.
