The need to join to other records was trivial for me.
I think the data model was too complex too fully decipher with a reasonable amount of effort, but this wasn’t a problem as it wasn’t necessary to get a decent answer (I might actually have got the optimal one if I hadn’t blundered and missed that Italia suffered a famine in the previous year—though I was uncertain on a number of points and wasn’t expecting to do as well as I did). In particular the wealth/population dependency completely passed me by.
Thank you for posting this.

Overall in terms of difficulty it felt OK.
