What is so important in 36-year-olds?

Figure 1 below compares the evolution of employment-population ratio (EPR) and the number of 36-year-olds in the U.S.  What can be so important in this number? I do not understand. Moreover, why this number is not important since 2010, as the projection from the number of 21-year-old shows in Figure 2? 

I do not say the 36-year-olds drive the EPR, but mere coincidence is rather unlikely.
