The MobiSim Population Synthesizer is a model and software for generating a synthetic population. A synthetic population is an artificial population composed of individuals associated with individual characteristics (level n) and constructed from the data known at the aggregated level (n+1) of the census. The advantage is then that social characteristics can be correctly analyzed at a fine scale while personal data remain anonymous and confidential. 

The MobiSim Population Synthesizer assumes the compatibility of the method with aggregated demographic data and precise geographic information but also a relevant linkage between the characteristics of the households (and the associated individuals) and the characteristics of the spatial dimension of the city's residential structure (housing and buildings). It is part of the MobiSim project developed by G. Vuidel and J.P. Antoni.
