Baby boom refers to a sharp increase in birth rates, especially after a war or during a particular period. Several other terms can replace this phrase, including population explosion, baby bulge, demographic wave, or population boom. These synonyms differ in the meaning they convey and the context in which they are used. However, each of these phrases seeks to describe a significant increase in the birth rate of a population in a given time. Population explosion, for instance, emphasizes the rapid growth of the population and the need to adapt to the change, while baby boom refers specifically to the surge in births.
