I read this book in the early eighties, it was a childrens book but I found it on my parents bookshelf (they were both teachers) and had obviously been around for a while.
As far as I can remember the world has gone to live underground as the surface is not safe any more. People live in isolation in individual cells but there is some form of communication (possibly unauthorised) with each other. Maybe they are allowed out to work but movement around is limited. Somehow a boy (I think) contacts an older person who tells them they are essentially prisoners and that they are being lied to and that people do live on the surface. He finds his way to the surface where he indeed finds that the air is breathable. He possibly has companions at this point.
This book obviously had a lasting effect on me as I often think about it, although I read quite a lot of science fiction around that time so may have got a number of stories mixed up! I tended to go for books that dealt with human interaction/emotions/communication so I'd expect this to have been a major theme in the book.
If anyone can help me out with this I'd be most grateful.
