Let me ask my question again.

I have the variables year state cnum candidat.

Year state and candidate have the usual meaning.

cnum is the consituency within a state.

So in one year I may have 5 states and within that I may have 10
constituencies and within those  I may have say 4 candidates each.

I want to compute the number of constituencies in each state.

I try to do this by : -

gen noofct=0

bysort year state cnum : count and now I want to store r(N) in noofct
variable. So the noofct variable will have the same value in any one
consituency. This is what I am not able to do.

Can someone tell me how to do this ?

Thank you,
Ashim.
