The Nuclear Weapons Ban Monitor prepares state profiles for each of the 197 states that can become party to global treaties for which the Secretary-General of the UN is the depositary. This means all the 193 UN member states, the two UN observer states (the Holy See and the State of Palestine), and two other states (Cook Islands and Niue). The state profiles contain summary data on the status of these states in relation to the TPNW as well as other treaties and regimes dealing with weapons of mass destruction, in addition to an overview of each state's compliance (for states parties and signatories) or compatibility (for states not party) with the prohibitions of the TPNW. The 197 states are categorised according to their position on the TPNW, with separate sections for the states parties, signatories, other supporters, opposed states, and undecided states. Within each of the five categories, the state profiles are presented in alphabetical order.
