- 1970 was the year when the leading edge of the baby boom turned 25. Note that the size of the population in this age band starts to climb steeply for here.
- In 2000, the leading edge of the baby boom turned 55, and the size of the population has been growing more slowly since then (or even a little before - heart attacks?). Recently, this population is almost flat.
- Note that the initial effect of the great recession is initially to boost the size of the unemployed slice (red), but now it's mainly causing people to leave the labor force altogether.
You can see that while the fraction unemployed shrinks and grows with each boom and bust, the not-in-labor-force category just continues to grow steadily.
