Correlates of War State-Year International Governmental Organizations (IGOs) Data

This is a state-year version of the Correlates of War IGOs data. I use it internally for merging IGOs data into state-year data.

Usage

cow_igo_sy

Format

A data frame with 1557 observations on the following 5 variables.

ccode: the Correlates of War state system code for the state
year: the year
sum_igo_full: the sum of IGOs for which the state is a full member in a given year
sum_igo_associate: the sum of IGOs for which the state is just an associate member in a given year
sum_igo_observer: the sum of IGOs for which the state is just an observer in a given year
sum_igo_anytype: the sum of IGOs for which the state is a member of any kind in a given year.

Details

The data-raw directory on the project's Github contains additional information about how these data were generated from the otherwise enormous dyad-year IGOs data provided by the Correlates of War project. Given the size of that data, and the size limitations of R packages for CRAN, the data I provide here can only be simpler summaries. If you want specifics, you'll need to consult the underlying raw data provided on the Correlates of War project.
