I just found this graph. The red line is the employment-to-population ratio of the USA. I've added some numbers - green for upwards trends, red for downwards trends:
One thing I'm very confused about is the scale. But what I'm interested in is what happened there (a can't read the numbers exactly, this is a best guess):
1. 1949-06 to 1953-06
11. 1953-06 to 1954
2. 1954 to 1957
12. 1957 to 1958
3. 1958 to 1960
13. 1960 to 1961
4. 1961 to 1969-04
14. 1969-04 to 1971
5. 1971 to 1973-09
15. 1973-09 to 1974-12
6. 1974-12 to 1979-03
16. 1979-03 to 1983
7. 1983 to 1990
17. 1990 to 1992
8. 1992 to 2000-06
18. 2000-06 to 2003-04
9. 2003-04 to 2007
19. 2007 to 2009: Financial crisis of 2007–2008
10. 2010 to 2014
I found a couple of things that might fit:
- 1961–63: Vietnam war?
- 1990 / 1991: End of the cold war?
- 2000-03: Burst of the dotcom bubble
Only for 19 I know that this was the Financial crisis of 2007–2008, but I don't know what changed that again in an upwards trend.
So my question here is: What actions / events had a major effect on the US unemployment rate from 1949 to 2014 as shown in this graph?
