Dependency ratio: The dependency ratio is the measure of the number of dependents (people who are not working or contributing to the economy) compared to the working-age population. In the case of post-World War II baby boom, there was an increase in dependents (children) which affected the dependency ratio.
Demographic shift: Demographic shift refers to changes in population characteristics over time, such as age distribution. The post-World War II baby boom led to a significant demographic shift by increasing the proportion of young people within the population.
Population aging: Population aging refers to an increase in the average age of a population due to declining birth rates and increased life expectancy. The post-baby boomer generation eventually grew older, leading to population aging and potential challenges for society's support systems.
