Answer:
The age between 18 and 35 of the male population would be the most affected if there was a war.
Explanation:
In a scenario where there is a war, the population that will be affected (negatively) the most will be the male one. In the case of war, in almost all countries in the world, it is the male population that is mobilized, while the female population is not (except in North Korea for example). In general, it is the male population between the ages of 18 and 35 that is mobilized, as this is considered the best age for it.
The male population of this age will have a very negative effect, or rather its numbers will drop in the total population. This will happen because there will be a lot of soldiers that will lose their lives on the fronts, doesn't matter will the war be won or lost. This will also have a negative impact on the female population of the same age group because a lot of them will remain without their husbands or partners, there also will be a lack of males for creating families.
