The static Sfb 3-microsimulation model is described in this paper. Following a short characterization of static microsimulation models, the concept and structure of the simulation model is outlined. This model is realized using the database system 1022 which supports relational data structures. An example using data of the Sfb 3-transfer survey illustrates the possibilities of the simulation model. The static Sfb 3-microsimulation model is generally suitable to work on microdata, since it supports a combined or separate processing of simulation, evaluation and adjustment.
