This paper focuses on an empirical analysis of the dependency between age structure and aggregate consumption and the composition of aggregate savings. In a long-run consumption function of life cycle type, different demographic variables have a conclusive, statistically significant effect. In investigating the link between demographic variables and the composition of aggregate savings, a simple simultaneous model is used, and a saving function and a house price equation are estimated. The result even here is that age composition matters for house price and savings. This conclusion is also made visible by a simulation experiment. Finally is the model used to ascertain the effect on the recent Swedish tax reform on savings.
