What is meant by demographic trough?

A demographic trough refers to a significant decline in a population's Birth Rate, leading to a period of lower population growth or even a decrease in the overall population size. This phenomenon often occurs after a demographic peak, where birth rates are high, and can result from various factors, including economic downturns, changes in societal values, or increased access to contraception. The implications of a demographic trough can include an aging population, reduced workforce size, and potential challenges for economic stability and social services.
