What was the cause of the subsistence crisis in france ?

The cause of the subsistence crisis in France was the population of France growing to rapidly or fast and Frances crop production could not keep up with the population.

The cause of the subsistence crisis in France was:

The population of France rose from about 23 million in 1715 to 28 million 1789. This led to a sudden increase in the demand for foodgrains.Production of grains could not keep pace with the demand. So, the price of bread which was the staple diet of the majority rose rapidly.Most workers were employed as labourers in workshops whose owner fixed their wages. However, their wages did not keep pace with the rise in prices.So, the gap between the poor and the rich widened.Things became worse whenever drought or hail reduced the harvest This led to a subsistence crisis, something that occured frequently in France during the Ancien Regime.

Hope you could get an idea from here.
