Final answer:
The doubling time for France with a growth rate of 1% is 70 years.
Step-by-step explanation:
The doubling time can be calculated using the rule of 70, where the doubling time is equal to 70 divided by the growth rate. In this case, since France has a growth rate of approximately 1%, we can calculate the doubling time as follows:
Doubling time = 70/1 = 70 years
Therefore, the doubling time for France is 70 years.
