Final answer:
The population decline occurred due to economic and social crisis causing a decline in birth rates and high death rates.
Step-by-step explanation:
The population of a country dropped from its peak of 75 million in 2020 to a concerning 68 million in 2023, marking a significant decline over the three-year period. This sudden demographic shift has raised numerous questions and concerns among policymakers, demographers, and the public alike. Various factors contribute to this decline, including a declining birth rate, increased emigration, and perhaps unforeseen economic challenges. The implications of such a population drop are far-reaching, impacting not only the labor force and economic productivity but also social services, healthcare, and overall national development. Policymakers are now faced with the urgent task of understanding the root causes and formulating strategies to reverse or stabilize this downward trend, ensuring the country's long-term sustainability and resilience. Public awareness campaigns, economic incentives, and targeted policies may be essential components of any comprehensive plan aimed at addressing this demographic challenge.
