In source paper you can see there are more points for France, 1965, 1974, 1998–1999 and it shows dünne decline. So where you have your stated problem?

I did a lot of research the first time it came out, I will need to find it again. But this is the idea, how can you conclude on something on a graph finishing in 2010 where your last figure is 1999 that you are actually comparing to something from 1974. The precise content of the questions also was questionable as obviously they were not the same between the different studies.
