Hi!
I'm in the social sciences too, and I'm writing (or rather trying to write) my lit review chapter.
I wrote 21,000 words and my supd told me to reduce it to 15,000. I managed to make it 17,000 and then I was told to make it 10,000! So, now my thord draft is around 11,000 words and I don't seem to be able to reduce it more!
My other chapters are:
Introduction (around 7,000 words as my research is based in a country other than the UK and I have to "set the scene")
Literature review (around 11,000 words)
Methodology (araound 13,000 words)
Analysis 1 (around 12,000 words)
Analysis 2 (around 12,000 words)
Analysis 3 (around 11,000 words)
Conclusion/Discussion (around 12,000 words)
That gives me total of around 78,000 words with a limit of 80,000
