How we calculate the PolitPro Election Trend
How we calculate the PolitPro Election Trend
The PolitPro Election Trend is more than a snapshot. We aggregate the data of all relevant polling institutes into a weighted average for the Parliamentary election in Slovenia. Because the classic voting intention poll (“Which party would you vote for if the election were held next Sunday?”) fluctuates for methodological reasons, our Election Trend provides a statistically robust data basis. It smooths out short-term outliers and reveals the real political dynamics over time.
By combining several data sources, we minimize the risk of random effects. Every survey carries a statistical margin of error (usually between 1.5% and 3%). Our poll check for Slovenia shows precisely whether a party's gain marks a lasting development or merely falls within the statistical uncertainty of a single institute.
The calculation follows a transparent mathematical model: recent polls carry more weight than older data. The historical forecasting accuracy of each institute also feeds into the calculation to offset methodological bias. The result is a valid trend line that maps the party system of Slovenia with precision.

How does the PolitPro Analysis work?
How does the PolitPro Analysis work?
Election polls are not predictions, but snapshots with statistical fluctuations. To obtain a realistic picture, we daily simulate 100,000 election outcomes based on the PolitPro Election Trend using the 'Monte Carlo method'. In doing so, we include typical voter migration and political trends. Our algorithm tests various scenarios – from small shifts within camps to political surprises – to determine the actual chances of success for parties and coalitions.
