Here's some good news- it's apparently not a worldwide decline in reading. While American newspapers are fighting to survive, French journals have gained readers in 2007, with a growth of 1.2%, especially the free dailies, unsurprisingly. Perhaps it's the "Sarkozy effect". Here's an incredible fact: 97.2% of the population of the age of 15 years and over reads at least one newspaper or magzine per month!
Postscript: I keep thinking that can't be true. I've read the Le Monde article five times now and that's what it says, but they must be leaving out the illiterates, because there is indeed illiteracy in France, about 8 percent by some counts. Anyway caveat lector.
