In The Netherlands, the Senate is elected by members of the provincial parliaments as well as the electoral colleges for the Senate, where the electoral colleges represent voters who do not live in a Dutch province. The voting for the provinces and the electoral college of the Caribbean Netherlands is weighted based on the population in each province or Caribbean municipality.
How is the weighting determined for the electoral college of non-residents (in other words: Dutch citizens living abroad)? I found that the number of members is determined by the number of registered voters, but I could not find how the vote of those members in the Senate elections is weighted in relation to those of the provincial parliaments or the electoral college of the Caribbean Netherlands. Is it based on the total number of registered voters? The number of voters registered for this particular election? The total number of residents living abroad (is that even known?)? The number of voters voting in the election? Something else?
