People’s ability to use websites declines between the ages of 35 and 60 by 0.8% a year, says the web usability specialist Jakob Nielsen. This is because they spend more time per page, and they visit more pages to find what they are looking for. This age group represents half of the population of the United States, has the best jobs, and spends the most money online. Nielsen advises to “test participants across the entire age range you’re targeting” and not to “believe everything your 25 year old web designers tell you about what’s easy.” (www.useit.com/alertbox/middle-aged-users.html)
