The Uncertainty Index and the Panic Index are the two indicators created by the T-Voice Coronavirus Observatory with the aim to estimate the levels of uncertainty and panic from people opinions during the coronavirus health and economic crisis.

Both are based on a 1 to 4 scale of panic or uncertainty rate respectively (where 1 means no panic or uncertainty and 4 implies high panic or uncertainty), which are then normalized to 0-100 through the min-max method.

The results are two indexes that can be directly used to compare different countries, regions or even cities, both at an aggregate level and over time.

In particular, values between 0-33 can be interpreted as acceptable levels of panic or uncertainty, while values above 33 are signals of worry.
