There are mobility gaps according to age and gender. The peak mobility age is around 40 years when individuals tend to be in their most productive years and fully employed. Males tend to travel further than females. This gender gap 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.
