A data frame with codes as columns.


Origin and Destination

Destination only


The Correlates of War (cow) and Polity 4 (p4) project produce codes in country year format. Some countries go through political transitions that justify changing codes over time. When building a purely cross-sectional conversion dictionary, this forces us to make arbitrary choices with respect to some entities (e.g., Western Germany, Vietnam, Serbia). countrycode includes a reconciled dataset in panel format, codelist_panel. Instead of converting code, we recommend that users dealing with panel data "left-merge" their data into this panel dictionary.
