How does economic development influence the stages of the Demographic Transition Model, particularly in terms of public health improvements?

Economic development greatly influences the stages of the Demographic Transition Model by improving public health, which affects population growth and stability. As a country develops, it often invests in better healthcare systems, sanitation, and nutrition. These improvements lead to lower mortality rates, especially among infants and children, allowing more people to live longer, healthier lives. For example, in a developing country that builds more hospitals and provides vaccinations, families may feel more secure and choose to have fewer children, knowing that more will survive to adulthood. This shift is crucial as it helps transition societies from high birth and death rates to lower rates, facilitating overall economic and social growth.
