Vote weights The provinces have different population sizes, so the members of the States-Provincial cast weighted votes, to ensure that each vote represents the same number of people. The weight is determined by dividing the population of the province by the number of seats in the States of that province. This number is divided by 100 and rounded.

The coalition parties VVD and CDA and their supporting party, the PVV, won 37 seats in this election, one short of an overall majority. However, the coalition-friendly SGP won the last needed seat, and it is expected that the SGP will help the cabinet in obtaining a majority on most issues.Rutte haalt met SGP meerderheid in Eerste Kamer, Elsevier, 23 May 2011

- * Democrats 66 missed a seat and the Socialist Party gained one due to a mistake of North Holland States-Provincial member Wim Cool, who voted with a blue writing device instead of the prescribed red one.D66 stem senaat blijft ongeldig , Nieuws.nl, 31 May 2011
