Union of Soviet Socialist Republics — Voting Analysis

Voting alignment is computed from UN General Assembly roll-call votes (1946–present). Agreement rates count the share of resolutions where both countries cast the same vote (Yes/No/Abstain), weighted by the inverse square root of the number of countries voting, to down-weight near-unanimous resolutions. Ideal points are estimated using a Bayesian item-response model (Voeten 2013) that places each country on a left–right policy dimension each session. Issue-area breakdowns use the topic codes assigned by the UN Bibliographic Information System.
