The date range for these opinion polls are from the previous general election, held on 12 September 2012, to the present day.
The seat projections in the graphs below are continuous from September 2012 (the last general election) up to the current date.
These seat estimates are derived from estimates by Peilingwijzer ("polling indicator") by Tom Louwerse, a professor of political science at Leiden University; they are not strictly polling averages, but the results of a model calculating a "trajectory" for each party based on changes in support over time in between polls conducted by I&O Research, Ipsos, TNS NIPO, LISS panel, Peil, and De Stemming, and adjusting for the house effects of each individual pollster.
The highest figure in each survey is displayed in bold, and the background shaded in the leading party's colour.
In contrast with many countries, opinion poll results in the Netherlands are generally reported in terms of the number of seats expected to be won rather than the percentage of the party vote (total is 150).
