In my world a nation has lost every man between the ages of 18-40 to war. What possible impacts on society from such a loss of life would I need to consider?

    $\begingroup$ All the young men? That means they lost the war, and the victors will come in and take over. $\endgroup$ – RonJohn Nov 12 '18 at 2:26

    $\begingroup$ You might look into what happened to Paraguay when it suffered a similar situation. $\endgroup$ – Cadence Nov 12 '18 at 2:29

    $\begingroup$ Of course the outcome of the war matters. And you should research Europe after the Great War. $\endgroup$ – RonJohn Nov 12 '18 at 2:30

    $\begingroup$ @RonJohn's right. Before WWI and WWII there were very few women in the workforce. Despite not suffering anywhere near the losses you're suggesting, the entirety of western culture shifted to allow women in the workforce, which required an incredibly complex stabilization of economies due to what would be an overabundance of workers once the wars ended and the men returned home. Regrettably, an analysis on that scale isn't just a book-length dissertation - it's a fair number of volumes. $\endgroup$ – JBH Nov 12 '18 at 4:34

    $\begingroup$ Look up the population pyramids for the WWI generations in Germany and France to see that there were still plenty of young males after the war. Turns out lots of young people are unsuitable for military service, or find employment in war-critical industries, or find other ways to avoid it. $\endgroup$ – user535733 Nov 12 '18 at 12:46
