Definitely not as much. In my experience, people in the US in their 20s (both during and post university) tend to be more in the mindset "I want a relationship" (and they're actively looking for one, using dating sites, personal networks, etc.) or "I don't want a relationship" (in which case they actively avoid it); whereas in France and European countries, people tend to be more neutral by default and then hop into a relationship when the right person comes along. Those are just my observations though- they could well be skewed.
