Important Note
These statements refer to the level of communication ability that a product or service demands, in order to use it. For a particular demand level, the 1996/97 Disability Follow-up Survey is used to calculate the total number of people who do not have this level of ability, and will therefore be excluded. The GB adult population was 45.6 million at the time of the survey. Please see the Framework section for more detail.
