The world is getting older. In Europe, for example, the median age in 1950 was 30 years. Today, it is 40. Over 65s will make up almost 25 per cent of the UK population by 2034, according to the Office for National Statistics, and by 2025 almost 1.5 million people in the UK will be living with an age-related disability.
Mat Hunter, chief design officer at the UK's Design Council, says that while the public sector sees this changing demographic as a problem, businesses should spot a chance to develop new products. "If the elderly become seriously unwell, then the state has to pick up the pieces," he says. "But the private sector should see this as an opportunity: a well-educated, perhaps the wealthiest, demographic in which to pick up new types of customers."
Car manufacturers are among the pioneers in this field. Mazda has introduced sliding doors on its M5 model to make access easier for their less supple clients, and Toyota has introduced larger typefaces on dashboard instruments.
Sometimes, the challenges facing citizens as they age are being addressed by ageing designers themselves. Kenneth Grange, a multi-award winning designer who is in his 80s, recently designed an oversized chair for Hitch Mylius, a furniture manufacturer, after noticing how much more difficult it was to rise from a chair as he grew older.
Some businesses are finding that designing products with older consumers in mind offers a degree of recession-proofing. OXO, a kitchen tool maker, has recorded growing sales numbers since the economic downturn, prompting Bloomberg Businessweek to point out that the company had "built a following by designing everyday items so people of almost any age or physical ability can easily use them."
But applying smart design to solutions for ageing populations is not only about developing new products. Services aimed at older citizens will also benefit from design innovation. The UK's Design Council has launched a competition inviting designers to devise ways of ensuring that older citizens do not become recluses. This could be a matter of applying simple design tweaks to a product or service. A dating website, for example, could offer options more relevant to needs or retirees than people in their 20s or 30s.
Service and process design elements will become especially important when addressing the next big challenge facing ageing societies dementia, which already costs the UK £20 billion a year, more than cancer, heart disease and stroke care put together. Telecare services, for example, are now widely available as a way of allowing dementia sufferers to stay at home for longer before requiring full-time supervised care.
