The year that economists might consider a trough is 1982
How to determine the trough year
From the graph, we have the following parameters:
- 1980 = 7%
- 1981 = 9%,
- 1982 = 11%
- 1983 = 8%
- 1984 = 7%
- 2985 = 7%
In this case, the year that can be considered a trough is the year when the rate of unemployment is at highest (i.e. 11% in 1982)
Hence, the year that economists might consider a trough is 1982
