In a less abstract sense, roughly 50% of my close friends who did the the whole "move to the burbs, ditch the social life, start a family" and who seemed to go missing for years are now divorced. Roughly in line with the statistics I suppose.
I'd go as far as saying that in the majority of cases when people in their 20s or 30s do this it's some sort of mix of social pressure and biological clock panic than an actual authentic decision.
