This is the time of year when our attention turns to this.
I went to my notes on previous ideas I've picked up over the years and found these, which I think originated from Dick Hudson at UCL - but not 100% sure , cos these notes were just cut and pasted for my use - never intended to go further - anyway - these are not MY wordsand not deliberately plagiarised!

an undergraduate last year who did a lovely study of play-ground language in her old primary school -
were the kids still using the same skipping rhymes etc as when she was there? Were they using the same ones as in the school down the road?
There's some literature on this - see

What are the grapheme-phoneme correspondences in the local accent, and do they show up in kids' spellings? See:

You might like to visit the LAGB fact sheets that I've been trying to build for some years now, though without much uptake -
