Subject | st: constructing a categorical gini measure |

Apparently you would like to measure inequality in "years of education", but all that is observed is data grouped into categories. And you have data on counties, not individuals. On the first issue, you could first convert your categorical variables to some "years of education" equivalent (your discipline and country conventions may tell you how to do that). But you're still then stuck how to handle the grouping. On this see the discussion last week on the list, and track back on previous Statalist discussion using Google. A more fundamental question is: why calculate a Gini from these sorts of data? Stephen ------------------ Professor Stephen P.

I have categorical data on educational attainment for each county. That is, I have the number and percentage of people in each county that have reached each level of education. My 16 educational attainment categories are: NoSchool00; Less than 4 Years; 5-6 years; 7-8; 9th grade; 10th grade; 11th grade; 12th grade; High School Grad; some college - less than one year; some college - more than one year; Associates degree; Bachelors degree; Professional degree; Masters degree; and Doctorate. I assume that each category must be converted into a years of schooling measure. Does anyone have any advice on how to construct such a gini measure for each indivdual county?
