Answer:
Overpopulation can be an issue if it continues.
Lack of resources (food, houses, etc) can be a subject of concern because of the larger number of citizens.
Larger population and a Natural increases in population size will be noticed.
Government might give out free contraception to its citizens to stop the increase.
Step-by-step explanation:
Overpopulation will be possible because there are more babies being born that people dying. France's population can increase exponentially if this situation continues and doesn't reach a stop.
Natural increase in a population occurs when birth rate is greater than death rate. This can also lead to a Natural decrease, when death rate is greater than birth rate.
The increase can cause the government to hand out free contraception to people.
The lower death rate could have been the result of good health care in the country, which means the population is taken care of. So it isn't necessarily a negative thing.
These are the things I could come up for the moment. I was just bored and I missed schoolwork and I started answering random questions lol.
Hope this helped
