Question

Quizplus · Accepted Answer

Mortality rates in less developed nations began to decline in the mid-twentieth century due to improvements in sanitation and health care. As access to clean water, vaccines, and healthcare improved, people were less likely to die from preventable diseases. This contributed to an increase in life expectancy and an overall improvement in living standards. While aging population may affect mortality rates in developed nations, it is not a significant factor in less developed nations. Rapid industrialization may have negative impacts on health due to pollution and hazardous working conditions, rather than improving mortality rates.
