I recently learnt that the number of UK civilians killed in the first world war is around 2,000. This seems surprisingly low but understandable when we realize that the UK wasn't subject to a land invasion and air warfare was then very primitive.
However, during the second world war it is the much higher figure of around 70,000. Although again the UK wasn't invaded it was subject to massive Nazi bombing raids. And the much higher figure will be due to this.
I've looked online for a breakdown of these figures into men, women and children but found nothing. If anyone has this breakdown to hand or know of a reference please let me know.
