Intergovernmental Organization Data, 1816-1964 (ICPSR 5520)
Principal Investigator(s): Wallace, Michael, University of Michigan; Singer, J. David, University of Michigan
This data collection describes the membership status of 148 nations in 237 inter-governmental organizations (IGO) that were in place between 1815 and 1964. Each nation is coded at five-year intervals for membership type in each listed IGO, such as full or associate membership, as well as for membership or non-membership in the international system.
