I was interested in this, mostly out of pure curiosity as I don't have particularly strong feelings either way about the SNP/how Scotland's finances are being handled, and so I've spent way too long looking over the budget reports you got these from. Simply put this is a complete misrepresentation of the data.
For starters, you might notice the local government figure has a superscript 2 by it, which if you'd read would have told you that a large amount of the money previously accounted for under that category was moved elsewhere from 2013-2014 onwards. Including the amount that was moved to other categories results in the spending in that area being essentially flat.
As for specifically health spending, that has risen by ~18% (11,181M to 13,168M) over this period, where the overall discretionary budget has gone up by ~7%. Incidentally about a 1/4 of this overall discretionary budget increase is due specifically to devolved powers being used to raise extra money for spending - 450million from devolved borrowing powers and 71million from increasing the higher rate tax band in line with inflation, as opposed to the larger increase to 45,000 in the UK generally. I'm struggling to see where this narrative of SNP austerity is coming from.
