Combined with the ~100K Russian casualties, ~200K combatants, if Putin adds another 150K then this will impact just 1.2% of its combat-age male population. The reduction in workforce is just 0.6%, but it is actually less than that, because most of the initially deployed soldiers were professional soldiers already, and weren't technically part of the workforce when the war started. So just considering the new conscripts, this is more like a 0.2% reduction in the total workforce.
I'm putting this here because I see a lot of discussions where people think that this will somehow "decimate" Russia's population, undermine their economy, strip the workforce bare, or whatever.
For comparison, their ageing demographics and low birth rate means that their population is shrinking by 86K people per month anyway. See: https://www.themoscowtimes.com/2022/07/29/russias-population...
Realistically, the effect of the sanctions is 100x greater than the additional mobilisation.
