Social issue
There is a certain fragility of income and social position in France. There are several ways to measure this. One possibility is to look at unemployment. Inside the European Union, in May 2017, France was ranked 6th country with its unemployment rate of 9.4 percent, according to Statista. Moreover, according to Observatoire des inégalités, France has between 5 and 8.9 millions of poor people, depending on the definition of poverty (if the poverty line is at 50 percent of the median standard of living or if it's 60 percent).
