Assuming average age distribution between 16 to 60 in the protesters, that leaves about 3 million non protesters in the same age distribution for serbia, with children and elderly making up the remaining population, which is around 6.7 million, give or take. That's 1 out of 4 working age citizens hitting the streets - not all people, but a huge chunk. It's safe to say there are going to be a lot of sympathizers in the non-protesters, a lot of people who wanted to protest but couldn't. There are definitely those who support the government, but I'd wager they're less than 15% of the total population, with the rest in opposition, or at least not in support of the government. The usual tipping point for revolution is lower - if 10-12% hits the streets, it's a strong signal that the movement behind that activity is taking power.
