In these cases, the wavefunctions of the system in question are represented as vectors, the components of which correspond to coefficients in a linear combination of the basis functions in the basis set used. The operators are then represented as matrices, (rank two tensors), in this finite basis.
General data can be found below: The highest rate for a single month is shared by November and December of 1982 with an unemployment rate of 10.8%. The year with the highest average unemployment rate was 1982 with an average unemployment rate of 9.71%. --.

The year with the lowest average unemployment rate was 1953 with an average unemployment rate of 2.93%.
That question may be the most important in economic history. If we can answer it, we can better grasp what perpetuates economic stagnation and what cures it. The Great Depression was the worst economic crisis in U.S. history. From 1931 to 1940 unemployment was always in double digits. In April 1939, almost ten years after the crisis began, more than one in five Americans still could not find work. On the surface World War II seems to mark the end of the Great Depression. During the war more than 12 million Americans were sent into the military, and a similar number toiled in defense-related jobs. Those war jobs seemingly took care of the 17 million unemployed in 1939.
