The misery index is the sum of the unemployment rate and the inflation rate for an economy. When tracked over time, the index provides a rough estimation of how well people are doing from an economic perspective. For example, when both the unemployment rate and the inflation rate increase, people are less likely to make purchases, which leads to an economic slowdown. Thus, an increasing trend in the index indicates worsening conditions for a populace, while a declining trend indicates an improving economic situation. A very high misery index can be considered a leading indicator of revolt within a country.
