This contribution presents theoretical considerations on the interconnections between life situation, life-style, choice of location and activity spaces, as well as empirical results on the basis of path analyses.

The latter is primarily mediated by lifestyle-specific location requirements and location decisions, which likewise influence travel behaviour.
