qmv_weights: Data on qualified majority voting (QMV) weights
In jfjelstul/eums: The European Union Member State (EUMS) Database

This dataset includes data on qualified majority voting (QMV) weights in the Council of the European Union. The total number of votes allocated across member states and the number of votes allocated to each member state have changed over time. This dataset tracks those changes and calculates the normalized voting weight for each member state for each period.
