Hello all,

I am interested in calculating an index of agricultural land inequality for Brazil. I'm thinking that a GINI coefficient would be a good approach given traditional uses of GINI, but I'm open to other approaches.

I have a data set for all municipalities in Brazil that consists of four columns for each municipality (rows): 1) number of family farms, 2) area occupied by small farm land use; 3) number of non-family farms; 4) area occupied by non-family farms.

What's I'm really hoping to attain is a value that can represent the relations between percent area occupied by non-family farms in comparison with family farms.

I can obtain the total area of the municipality from municipality shape file, but I don't think it makes sense to have a simple ratio of non-family farm area/municipality area as there will be various other forms of land use.

Any suggestions on how to calculate a spatial GINI using this data set, or a different statistic that makes more sense would be greatly appreciated

Dr Google for country specifics and its application. In short there are no built-in tools, for direct calculation, but given the data and existing tools, it can probably be calculated
