Location quotient - how to calculate

[Giorgio Piccitto]

Dear all, I would like to know your feedback about something I am struggling with since a lot.

I would like to calculate a modified version of the "location quotient" on my data.

This quotient is given by the formula (e_i\e) / (E_i\E), where:

e_{i =} quota of workers in the fifth quintile of job quality distribution in region A of country A
e = quota of total workers in region A of country A
E_{i =} quota of workers in the fifth quintile of job quality distribution in country A
E = quota of total workers in country A

I would like to do this for several regions and countries. I have calculated the quintiles, but I do not know how to calculate this index.

Do you have any clue about that?

Thanks, best, G
