Is it wrong to say 'the annual per capita income 'in' country x...'?
(I know that 'the annual per capita income 'of' country x...' is right)

If you think logically , we can find out.....

when you say per capita income of a countrry , it is a macro economic measure for the whole country

per capita income in India would be applicable in certain subsets

i think-- per capita income in india ,of the minorities is very low....

is OK...What do you say????

Thanks for the responses. I came across a sentence that used 'per capita income in' so I think it is not wrong to use 'in' but as you guys mentioned, it does depend on the context.
