The response that most accurately examines the causes of rapid population growth in Latin America since 1945 is:
More people were born and fewer people died, which expanded the population and created new pressures on countries’ infrastructures.
This reflects the demographic trends observed in the region post-World War II, characterized by higher birth rates coupled with decreasing mortality rates due to improvements in healthcare, sanitation, and nutrition, leading to population growth and increased demands on infrastructure and services.
