This indicator captures state memberships in the intergovernmental organization "World Trade Organization" (WTO).
Coding rules
- The data is based on the Correlates of War IGO Version 3.0 dataset which expands the original Wallace and Singer (1970) dataset to 1816-2014. Data after 2014 was extended by CRC 1342 researchers.
- The ordinal indicator captures no (=0) or full (=1) membership in the intergovernmental organization; if applicable, further statuses are coded.
- Years in which the intergovernmental organization was not existent/not yet founded are coded as
99. - Unless noted otherwise, membership is reported valid as of December 31st of a given year.
For further coding rules see the codebook of Pevehouse et al. 2019.
