There is a clear variation in mobility according to age and gender. The peak mobility age is around 40 years when individuals are in their most productive years and fully employed. The gender differences in mobility can be linked to various factors such as vocational differences, income differences as well as a more conventional role assumed by woman in several households. This gap is however less acute among younger age groups.
