This volume describes the results of a feasibility study for a microsimulation model of family dynamics (FAMSIM) that could be applied to a number of countries utilising the rich data source collected in the context of the Family and Fertility Survey (FFS) in more than 20 industrialised countries. This also involved the development of FAMSIM-Austria, a prototype model based on the Austrian FFS conducted in 1996 by the Austrian Institute for Family Studies.
