Rule Of 70 And Population Doubling Time
The human population growth rate was approximately 0.1% in 1650 C.E. and 1.2% in the modern era, as shown in the table. All of the following statements concerning these growth rates and their corresponding doubling times are true EXCEPT:
| Time Period | Growth Rate (%) |
|---|---|
| 1650 C.E. | 0.1 |
| Modern Era | 1.2 |
A
An increase in growth rate results in a decrease in doubling time.
B
Using the Rule of 70, the doubling time for the modern population with a 1.2% growth rate is approximately 583 years.
C
For a 0.1% growth rate, the doubling time would be years.
D
Modern advancements in healthcare and technology have led to a higher growth rate, thus a shorter doubling time compared to historical rates.
