Membership status is coded as follows:

  • Countries included are those that have signed and/or ratified the agreement in question. This means that countries that have signed but failed to ratify an agreement will appear in the table but with a status of "0" in all years, since the agreement would only enter into force for them if/once they ratify.
  • Where the membership data source provides it, membership status is based on the year of entry into force.
  • Where the membership data source does not provide entry into force data, membership is inferred from the year of a country's ratification, so long as that year occurs after the entry into force year of the agreement.
  • Because status reflects entry into force, status is "0" for ALL countries from the date of signature of the agreement until the date the agreement enters into force generally.
  • NB: Membership status can return to 0 from 1 if a country withdraws from an agreement (and they may, subsequently, become a member again).
