Underdeveloped nations have high birth rates, high death rates, and low life expectancies. Based on what you have learned about barriers to economic development, why do underdeveloped nations have these demographics?

Answer:

Underdeveloped nations often face barriers such as poor healthcare, low education levels, war, political instability, and lack of access to modern medicine and family planning. These factors lead to high birth rates (as families have many children to ensure some survive) combined with high death rates and low life expectancies due to disease, malnutrition, and conflict.
