A disability in a person can be in any form from mental and physical impairment to learning disability. Conversely, what is termed disability by one may not necessarily be for another person with a much similar impairment.
According to the Equality Act of 2010, a person is said to be disabled if he has a mental or physical impairment that is long-term and has a substantial negative impact on his ability to carry out his normal daily tasks. By long-term, this means at least a 12 months duration. While substantial describes not trivial cases. However, Addiction to non-prescribed drugs does not fall in to the problem of disability.
That said, various data abound for disability cases of people living in the United Kingdom.
