The following two slides contains a range of statistics, both global and Nigeria centric.

Why are these figures important? They are a very quick way of making you realise that we are all part of a very diverse society, individuals involved in designing products or services need to recognise that they are only representative of a small segment of the potential market. Designing for diversity is a challenge, but also very important if organisations are to succeed in an increasingly competitive environment.

If designers do not consider the capabilities of older users when designing products, users experience difficulty in using the design causing;

  •  frustration
  •  accidents
  •  rendering the design unused or misused
  •  users will not buy the design
  •  loss of revenue from sales
  •  damage to reputation
  •  and a possible lawsuit

By 2050 there will be 2+ billion people aged 65+ years…

                        …….. now, that’s a BIG market!
