The DDA (Disability Discrimination Act) states that service providers
must not discriminate against disabled people. A website is regarded as a
service and therefore falls under this law, and as such must be made
accessible to everyone.
Some organisations are making accessibility improvements to their
websites, but many are seemingly not making the accessibility
adjustments. Disabled people don't access their website, they say, so why
should they care?
Why you should care about disabled Internet users
The statistics on the number of users who may face difficulties due to
your website's accessibility are quite startling:
* There are 8.6 million registered disabled people in the UK - 14% of the
population (source: DRC)
* One in 12 men and one in 200 women have some form of colour blindness -
9% of the UK population (source: Institution of Electrical Engineers)
* Two million UK residents have a sight problem - 4% of the population
* There are 12 million people aged 60 or over - 21% of the UK population
(source: UK government)
Although there is inevitably some overlap between the aforementioned
groups, adding up these numbers provides a total of 48% of the UK
population that could potentially face problems with your website's
accessibility. That's an extraordinarily high number.
It's not just disabled users who can't access your website
Non-disabled people may also experience difficulties with your website's
accessibility. Not everyone is viewing your website on the latest version
of Internet Explorer, with all the plug-ins and programs that you may
require them to have for optimal access.
provide alternatives, then your website won't be accessible to a number
of web users. The following examples are a common occurrence:
* Users on slow connections regularly turn images off to enable a quicker
download time. Some browsers, such as the text-only Lynx browser do not
display images at all.
* Not every user has downloaded the latest Flash program that's needed to
access your site. Additionally, the download time on Flash websites often
takes so long that users lose patience and don't even wait to see the
content. Just 25% of web users in the UK are connected to the Internet
via broadband (source: National Statistics).
often through mouse functions, buttons, or other actions from the user.
unsupported by about 5% of web users, either because they have turned it
off to prevent pop-up adverts or because their browser doesn't support it

* PDAs, mobile phones and WebTV have limited support for large images,

alone an estimated 58 million PDAs will be sold (source: eTForecast) and
one third of the world's population will own a wireless device (source:
