Methodology
In each constituency Europe Elects considers polls published with a sample size in the previous 90 days, using only the latest poll published by each firm. Polls asking directly about the European Election are preferred, but since those are rare and national polls are plentiful, the latter are often used. Wherever no polls are available, as in the case of the German-speaking community in Belgium, the 2014 election results are used. Polls with a sample size of <501 are ignored. Europe Elects subject matter experts disregard or include certain pollsters based on external evidence (such as new paper articles) relating to credibility. In France, whenever no recent national parliamentary polls are available, we use an average of the Presidential polls and project the value to the national party affiliated with the respective candidate.
The constituency results are calculated probabilistically for each poll included in the projection using the correct local electoral law, a factor that is unique to the Europe Elects model, using weighted Monte Carlo simulations, essentially simulating the election many times over and over again to achieve the probability distribution of the results. The results for each constituency are combined by averaging the probability mass functions (those graphs above that look like a bell curve) calculated for each poll.
These result are then combined into a single European result by convolving the probability mass functions of the parties in each European Parliament group, for example calculating for S&D the probability that the PD will get x number of seats plus Labour will get y seats plus Spanish PSOE will get z seats and so on for every party in S&D; the same is done for each group independently.
This method leaves us with separate bell curves each one of which we take the median result from as the predicted number of seats for the EP group. The sum of the medians will not add up to 705, one more step is required for that, but it will be close to it.
The reason for the medians not adding up to the total seats can be understood imagining 3 parties competing for a single seat in one constituency, each one having equal probability of winning. The probability mass function for each party will show it with a 1/3 probability of winning one seat and a 2/3 probability of netting 0 seats. The median result will therefore be 0 for all three, with a confidence interval of 0-1. The sum of the medians 0+0+0 = 0 not 1, yet the result is probabilistically correct.
The median result for each EP group is normalized to the total of 705, making up for all the cases like the one described above by distributing the missing seats proportionally.
The grouping of the parties in the European Parliament is done by the team members of Europe Elects. Parties already represented in the European Parliament are kept in their current group. For new parties or parties that aren’t represented yet, we keep a close eye on (and often communicate with) relevant national parties to assess which group in the European Parliament they will join. We make our information transparent in the ‘party’ section on our website for each country. Hence, our projection is unique in that it aligns new parties with the existing families, rather than as an amorphous “new parties” group. In this context, it is important to differentiate between ‘Non-Inscrits’ and ‘unaffiliated.’ Non-Inscrits have made the explicit decision to not have a relationship with a group in the European Parliament. For example, they either sit as part of the Non-Inscrits or told Europe Elects that they would not join any group if elected. Parties labelled as ‘unaffiliated’ never made such a statement. There is no indication of which group they would join in the EU Parliament if elected, if any.
