Working in the disability inclusion / access space, I have not found the Census data useful for my work. It doesn't tell us anything about the particular disability, or more relevant, access needs of residents. "Assistance with daily living" is incredibly ambiguous, and my recollection (this may be hazy though!) from last census was that it didn't make clear different age categories: my four year old requires "assistance with daily living", but his needs are vastly different to my 21 year old niece who uses a wheelchair and cannot communicate verbally.
