Projection

What the Riksdag would look like today

349 seats. Four per cent threshold nationwide, or twelve per cent in one constituency. Sweden uses the modified Sainte-Laguë method with a first divisor of 1.2 and levelling seats; we simplify by using the classic method, which can differ by one or two seats for small parties.

Context

What this forecast can and cannot do

For Germany we have calculated how far polling averages were off depending on the distance to the election: two years out a good four points per party on average, one week out a good one and a half. For Sweden we do not have this history yet; the order of magnitude is likely to be similar. The analysis for Germany shows the table.
