Demographic Consequences of Pandemics on the Age Structure of Cities

Quick fact

During the 1918 influenza pandemic, cities like Philadelphia and London experienced death rates so high that they temporarily lost a significant portion of their elderly population, causing a visible 'bulge' in the age pyramid that persisted for decades.

Why this is interesting

Imagine a city where one year, death suddenly strikes the elderly at a much higher rate. How does that change the population's age balance for decades?
