I used the term "unique values" because STATA uses it when you type "codebook country". I don't remember the english word for "Variablen-Ausprägung", so i could not describe it better as in this example. Maybe you do?

Thank you for your time.

it's not entirely clear to me what you mean by "detect unique values".
does this give what you want?

***
gen country_unique = .
replace country_unique = Country if Country[_n] != Country[_n-1]
***

best,

I would like to know if and how I can detect unique values of one
variable and write them into a new variable.

For Example:

Country

Australia
Australia
Belgium
Belgium
Germany

I need a variable which is:
unique = "Australia" "Belgium" "Germany"

I don't need:
unique = "Australia" "Australia" "Belgium" "Belgium" "Germany"

Thank you!
