 
 <prompt> ```For economics, the Gini coefficient (wey sometimes dey call Gini ratio or normalized Gini index) na measure wey dem use take check how income or wealth dey share for people wey dey one country, and e dey the most common measure for inequality. E be Italian statistician and sociologist Corrado Gini wey invent am and e publish am for im 1912 paper "Variability and Mutability".

The Gini coefficient dey measure the difference for values for one frequency distribution (for example, levels of income). If Gini coefficient na zero, e mean say everybody get the same thing (for example, everybody get the same income). If Gini coefficient na 1 (or 100%), e mean say the inequality dey high (for example, if one person get all the money and everybody else get nothing, the Gini coefficient go dey close to one). But if the value pass one, e fit be say some people get negative contribution to the total (for example, dem get negative income or wealth). For big groups, values wey dey close to or pass 1 dey very rare. Because of how dem normalize the population and income share wey dem use take calculate the Gini coefficient, e no too dey sensitive to the specifics of the income distribution, but e dey show how income dey vary compared to other people for the population. The only time wey e fit change na if dem redistribute wealth wey go give everybody minimum income. If the population dey arranged, if their income distribution dey close to one well-known function, then dem fit calculate some representative values.

Now, provide a numbered list of answers to these questions:

1. Wetin I fit use take measure the difference for income for one population?
2. If I use am, how even Steven go look like?
3. Who invent this way wey dem take measure am?
4. E publish any of im work?
5. When?
6. Wetin e call am?
7. Wetin this coefficient dey mainly use measure?
8. For wetin?
9. Dem dey use am for anything apart from income inequality?
10. Wetin else dem dey call am?
11. If only one person somehow get all the money and everybody else get nothing, wetin the Gini coefficient go be?
