The trend line for the percentage of 25-54 year olds employed

If you look at yesterday's post, you can see that after this percentage fell from about 80 to 75 from Dec. 2007 to Oct. 2009, it stayed there for about two years. So the trend line I have starts in Oct. 2011. Maybe that is when the recovery actually began.

So I start the trend line there. Early on, it looks like about 12 months are above the trend line. Then for awhile there are points both above and below the trend line. But each of the last 10 months is above the trend line. Not sure if this is a good sign or not (is the economy overheating?).
