UPSC Civil Services Model Paper 4

Gini coefficient:
It is intended to represent the income distribution of a nation's residents and is the most commonly used measure of inequality.
A nation with a Gini score of 0 has perfect income equality, and a score of 100 has perfect inequality (i.e. all the wealth is owned by a single person).
If the Gini coefficient of Nation A is higher than nation B, there is no guarantee that Nation A will be wealthier or poorer than Nation B.
For e.g. Brazil has a higher Gini than Canada, the latter is wealthier. So, statement 1 is NOT correct.
It is possible that a more unequal nation has better social indicators than a more equal nation. For e.g. the USA has a higher Gini coefficient than India,yet the former has better social indicators. So, statement 2 is NOT correct.
No conclusive inference can be drawn about statement 3. So, statement 3 is NOT correct.
