st: Merging and counting variables

["DE S" <enchantee_76@hotmail.com>]

Hello Statalisters,

I've reviewed the Stata Manual and to no avail.  Here is my question.

I have a master set with R county and states.  County and State are appended 
to read, "New YorkNY", for example.  I also have an association dataset that 
lists all national organizations and their corresponding county/state, also 
appended as "New YorkNY."  I want to merge the datasets and find out how 
many associations exist in each respondent's county.  For example, if R1 
lives in NY, NY, I want to have a variable that will spit out "100" for the 
100 organizations that exist there.

I'd appreciate your help immensely.

Thank you,
Dari E. Sylvester
