Due to the ageing population in industrialized countries, the rate of disability among people with the capacity to travel is increasing, adding to the demand for an accessible environment, transport and services - which adds to the market value of the accessible tourism segment. Much of the senior population has significant income and the desire to travel, both in their home countries and abroad, and their expenditure tends to be higher than that of tourists in general. Because many people with disabilities and older people are no longer active in the workforce, they have the possibility of travelling throughout the year, which helps to reduce the seasonality of demand experienced by many destinations.
