Gini coefficient fails to rank perils for bikers: leopards and SUVs!

The Gini coefficient is a measure of variability in a variety of phenomena. It has become popular thanks to its applications to inequality of income or wealth where For example, inequality is lower in Italy with a coefficient equal to 0.35 and higher in South Africa where it is equal to 0.6.

However, the measure surprisingly fails to account for the puzzling empirical evidence suggesting that the risks that bikers in Italy or in South Africa are alike : both SUVs and leopards are little pleasant encounters as one rides along!

Perhaps Corrado Gini was not a biker?! Additional information about this Italian statistician with a taste for interdisciplinarity in the next blog entry.
