These are interesting graphs, but at least in some of them the focus around 2012 seems arbitrary. "Time spent partying" started decreasing since 2006 at a rate (-2 mins/day in a year) that you only see from 2014 to 2015. "Total Consumer Credit Outstanding" is almost linear from 2009 to 2014, why is 2011-2013 so special? Ditto for "Number of satellites in orbit" which looks essentially linear from 2000 to 2014.
Some graphs are correlated and probably share trends, like "Time spent Partying/socializing" is negatively correlated with "Young Adults Reporting No Sex in Past Year".

Most of these graphs say that 2012 was a somewhat normal year, continuing trends that were going for a while.
