I think it's just a reflection of what is happening in the Canadian population. When you look at the composition of workers aged between 20 and 69, we have seen a shift to older workers. Right now the average age of a new person in the public service is 34. Ten years ago it was 32. Another ten years before that it was probably around 30 years of age. So it's just a reflection of the global aging that is occurring in the general population.
