How popular are the competing blocks?
The plot shows weekly levels of support in the form of predicted vote shares. To view detailed results for a specific week, move the marker over the plot (on touch screens: tap). The weeks are identified by the Monday on which they start. Uncertainty is illustrated by 95% prediction intervals.
If an election had been held today, the vote share of the conservative block would have been expected to lie between 35.7% and 41.8% with a 95% probability, and the median prediction would have been 38.7%. At the next election, the conservative block is expected to receive between 35.1% and 47.8% of the votes cast.
Who will get a parliamentary majority?
The plot shows the probability that a party constellation would get a majority if an election had been held during a given week.
The conservative block currently has a 2.1% probability of winning a parliamentary majority at the next election. If an election had been held today, this block would have had a <1.0% probability of winning a majority.
How popular are the parties?
The plot shows weekly levels of support in the form of predicted vote shares. To show or hide a party, click on it in the list above the plot. To show only a single party, double-click on it while it is visible. To show all parties, double-click on a hidden party.
If an election had been held today, the Labor Party (Ap), at 24.4%, would have been predicted to get the largest vote share, ahead of the Conservative Party (H), at 21.7%. The Centre Party (Sp) has seen the largest gains since the last election, adding 7.6 percentage points to its predicted vote share. The Progress Party (FrP) has seen the largest losses, dropping 5 percentage points.
Who will get above the 4% threshold?
The plot shows the probability that a party would get above the 4% threshold if an election had been held during a given week.
The Red Party (R) currently has a 37.3% probability of getting more than 4% of the national vote at the next election. The equivalent probability for the Liberal Party (V) is 25.1%. For the Green Party (MDG) it is 24.5%, and for the Christian Democratic Party (KrF) 22.5%.
How many seats will each party get?
The plot shows weekly levels of support in the form of predicted parliamentary seats.
If an election had been held today, the Labor Party (Ap) would be predicted to be the largest party in parliament, with 46 seats, ahead of the Conservative Party (H), at 40 seats. The Centre Party (Sp) would be predicted to gain the most seats, adding 16 compared to the last election. The Progress Party (FrP) would be predicted to lose the most, obtaining 8 fewer seats.
How is party support geographically distributed?
The map shows the total predicted vote share for the conservative block at the next election. Move the marker over a district for details (on touch screens: tap). Click and drag to zoom. Double-click to return to the original position (on touch screens: tap with two fingers).
Vest-Agder is the most Right-leaning district in Norway, with a 50.8% predicted vote share for the conservative block at the next election. Nord-Trøndelag is estimated to be the most Left-leaning, with a 25.1% predicted vote share for the conservative block.
How do the polls look?
The reported date for each poll is the midpoint between the start and end of the data collection.
In addition to national polls, the plot shows the estimated trends of support in the population. Because the model corrects for differences between polls and actual results in previous elections, some trends are adjusted slightly up or down relative to the moving average of the polls.
How does the model work?
The results reported above are based on 15,000 sets of simulated values from a Bayesian model. To get a satisfactory grip on the uncertainty of the results, all parameters are estimated simultaneously via simulation: No point estimates are made until the joint probability distribution of all the parameters has been estimated.
The model accounts for both random variation and polling bias, although the latter is fairly limited. Such bias has two likely explanations: (1) The voters of some parties are more prone to answer surveys (and the polling companies are not fully able to correct these differences through weighting), and (2) the voters of some parties have a lower turnout rate.
The current version of the model relies only on national polls because this proves to give the most accurate results. However, the model uses prior election results to estimate how party support is typically distributed among districts. This makes it possible to use the national trends to predict results at the district level.
The predictions for the next election are based on five elements: (1) Vote shares at the last election, (2) the degree of change in each party’s vote share from one election to the next, (3) current party support, (4) the degree of change in each party’s support from one week to the next, and (5) the degree of covariation in how support for each possible pair of parties evolves on a weekly basis.
To keep track of new polls, this project relies on Poll of polls and the project might not have been feasible without their effort to systematize the polls. The idea behind this project is to complement their contribution by going further in terms of modeling party support and predicting election results.
