Chapter 4, Problem 31A

Summary Introduction

To analyze: The birthrate or the death rate is more important to human population.

Introduction:

The rate of the increased population depends on birth and death rates, which are influenced by population age structure. Birth occurs mainly to people in younger adult age groups. If younger is less than older adults, mortality is high. Every family has an average number of children, so birth rate is high.

Explanation of Solution

The birth rate is more important than the death rate because there is a concern about declines in the birth rate in developing countries. The fertility rate tends to be high in poor resource countries, but due to high maternal and paternal mortality, there is a reduction in birth rates.

The birth rate tends to change more often than the death rate. It also predicts resource and competition for survival. Increased fertility rates can have remarkable effects on the overall structure of populations.

Conclusion

Hence, birth rate is more important than death rate because we learn about survival resource and survive for the fittest.
