British and French in 'not arrogant' shocker

I am indebted to the lovely people at Pew Global for making their survey on 'the American-Western European Values Gap' available online, so I've picked the best bits and knocked up another couple of charts.

Asked this question - “Our people are not perfect, but our culture is superior to others” - the polling results look like this:

Interesting, no?  The supposedly self-satisfied / exceptionalist French are the least confident / arrogant across all age ranges, while the supposedly cringing / perpetually apologetic Germans have the smuggest youngsters (well, under 30s).  Our American chums lead in self-belief in the two other age breaks.  Meanwhile, what is going on with Britons born between 1962 and 1981?  Most of that cohort would have known Thatcher, Major or Blair as the first prime minister of their adulthood, two of whom were not exactly shrinking violets.  

The breakdown by gender is not as dramatic, but is of interest nevertheless:

Taking a wild stab in the dark, I would imagine that women lead in most countries as there are more of them among the older.

Shame that Pew did not poll the Chinese....
