Given that the one who would (most likely) be coding it hasn't a clue what you're talking about...probably not 
http://en.wikipedia.org/wiki/Gini_coefficientBasically, it is a measure of inequality of income. In a realm where everyone has equal income, G=0; in a realm where a single person has all the income and everybody else zero, G=1. It is independent of sample size for large N (so may be skewed in very small realms) and of average income (so poor realms could have a good score) and is easily calculated if you have a list of the incomes of the realms (the 3rd formula on the wiki is probably the one you want to use).
