Matching postcode to state

[Julia Dundeldoch]

Hi,

I have a dataset, where each observatiob indicated their individual postcode. I have another dataset with postcodes and the corresponding states.

Postcode variable in both data sets "PLZ".

Since the the postcodes don't match 1:1 a merge doesn't seem feasible.

What's the best option to list the corresponding state to each observation in the original dataset?

Many thanks!

The solution is a merge. Say you have your person data open, than you would type something like merge m:1 PLZ using plz_data.dta where plz_data.dta is the file that relates postcodes to states.
