This is a complete (I believe) data set on Correlates of War states and Gleditsch-Ward states, a byproduct
cow_states that leans largely on the
state abbreviation variable.
A data frame with 16936 observations on the following 6 variables.
a Gleditsch-Ward state code
the state abbreviation, which was the greatest source of agreement between both data sets
the state name as it appears in the Gleditsch-Ward data
a Correlates of War state code
the state name as it appears in the Correlates of War data
a numeric vector for the year
data-raw directory on the project's Github contains more information about how these data were
created. I'm going to use it for internal stuff. The workflow is going to treat the Correlates of War state system
membership codes as more of the "master" codes, for which the user can add Gleditsch-Ward identifiers as they see
fit. Data are extended to 2020, assuming no changes to state system membership for either data set.
