According to CBS data, bicycle use varies in each town. This applied in the 1980s and 1990s too, when the percentage of bicycle journeys in 48 municipalities with populations between 50,000 and 200,000 varied from 10% to almost 40%. These differences still seem to apply and can only partially be explained by differences in the size and composition of the population, the location in relation to other towns, economic characteristics and the quality of the local public transport, for example. Simple figures give clear indications that municipal traffic policy, and thus bicycle policy, also affects the extent to which people cycle in a municipality.
