Conversion of the Correlates of War country code into conventional ISO code

cow2iso

This is a Stata do-file for converting the Correlates of War (COW) country classification into the conventional United Nations ISO 3166-1 alpha-3 (ISO3) nomenclature. Some observations cannot be merged as they refer to historical countries that do not exist anymore.

Please refer to the COW website for eventual classification changes and updates. All remaining errors are my own.

cow2iso.do contains the code to merge iso_country_codes.csv and cow_country_codes.csv, then stores the output in cow2iso.csv.

List of variables from cow2iso.csv:

Variable	Definition
cow_id	Correlates of War country unique identifier
cow3	Correlates of War country three-letter code
iso_id	Official ISO country unique identifier
iso2	Official ISO country two-letter code

valid_from	Starting year for validity
valid_until	Ending year for validity, still in use if empty
