17; that was in 1918. They quickly increased the electoral threshold to 75% of a seat then. Then, in 1933 when there were 14 parties in parliament again, they increased it to 100%. After that, it has always hovered around 10 parties, and it's still one of the lowest electoral thresholds in the world; most countries have it at 5%-10% of the total vote.

To put that in context: that is one party per million residents.

When you put it like that, it doesn't really sound like that many parties...

To me it actually sounds like more. That would mean about 324 parties in the USA.

I like the sound of that.

When that happened, there were fewer residents, so it was more like one party per half million.

Ah, I thought the GP was referring to when the LPF split into individual fractions.

If I count correctly, the 2003-2006 Tweede Kamer had 9 party fractions in it at the start and had 5 split-off groups, so there were 14 fractions in the end. Maybe there were more somewhere in the meantime?

But of course I don't know what xenobioticants was thinking about.
