Quick fact
In Russia, the population pyramid still shows two distinct 'dents' from World War II's massive losses, and the echo of that missing generation continues to affect age structure today, such as through a smaller working-age population.
Why this is interesting
Have you ever looked at a country's population pyramid and seen a sudden 'bite' taken out of one age group? That dent is often the ghost of a war fought decades ago.
