A new report from the Centre d'Analyse Stratégique on French "social realities" compared to the rest of Europe contains a wealth of statistical data. I will be commenting on various aspects of this report in the weeks to come. One thing is clear: the overwhelming majority of the French report themselves to be "happy" but "anxious." Objectively, France isn't doing badly. Subjectively, the French are of two minds.
I've fixed the link. Thanks to francofou for pointing out the error.
