3 ACCESSIBILITY
Access to an activity or service means the ability to participate in the activity or make use of the service. Access to a service does not imply being able to travel to the service, since the service could be brought to you or could be accessed on-line. It is not necessary to go to a shop if the shop will accept orders by telephone or on-line and deliver goods to your house. Similarly, access to an activity or person may well be achievable without physical mobility. But if access to something can only be achieved at a particular location, then accessibility requires the mobility to reach that location.
Accessibility requires knowledge, ability and financial means (Table 1).
