In 1900, less than 10 percent of the population was over 55. By 1960, this percentage had increased to 17 percent. More than 30 percent of the population will be over 55 by the year 2030; increasing to nearly 35 percent by 2050.
Not only will more people be over 55, but they will live longer as well. People over 85 will increase from about 3 percent of the population today to about 7 percent by 2050.
As a result, increasing numbers of the population will need assistive technology. This is why accessible websites are so important.
