Final answer:
The sharp decline in death rates during Stage 2 of the Demographic Transition Model is primarily due to improvements in healthcare, nutrition, and sanitation from industrialization, while birth rates remain high, causing rapid population growth.
Step-by-step explanation:
The sharp decline in the death rate during Stage 2 of the Demographic Transition Model (DTM) is commonly attributed to several key improvements typically associated with industrialization and urbanization. As a country industrializes, it invests in better healthcare, nutrition, and sanitation measures, all of which contribute significantly to reducing the death rate, particularly among infants and children. Additionally, adults benefit from advancements in medicine, leading to longer life expectancies. However, during this stage, the birth rate remains high due to cultural traditions and the previously high infant mortality rate that encouraged larger families. The result is a rapid population growth, where the socioeconomic shift has yet to reach a balance between lower birth and death rates.
death rates decline sharply in Stage 2 is: Advances in healthcare, nutrition, and sanitation associated with industrialization significantly reduce death rates. Simultaneously, the birth rate remains high due to cultural traditions, leading to a population surge.
