Norwegian regional stereotypes go something like this:
The North: Country hicks. (It’s inevitable, isn’t it?) Fisherman, sheep farmers, or (if Sami) reindeer herders. One Norskie friend once said, “After all, before electricity came, all there was to do in Northern Norway in the winter was get drunk, get laid, or get religion”; another friend shot in “Yeah, and now you can also watch television.” Net importers of government money in the form of 60,000 jealously guarded subsidies. You know all the jokes about <insert ethnic group here> and their, um, fondness for sheep? For the North, you can tell the same jokes - with your choice of sheep or reindeer.
Central Norway/Trøndelag: Not the sharpest knives in the drawer. Take three years to make up their mind about anything, but once their minds are made up, it will take the Second Coming of Christ to convince them otherwise. Fond of strong drink, especially of the (illegally) homemade variety. All the men have moustaches, and so do some of the women.
The West: Inbred. Suspicious of outsiders. Speak dialects that are impossible to understand, probably on purpose. Religious. Mental stability suffers due to excessive rainfall and never seeing the sun for more than five minutes at a time.
Bergen: Same as the rest of the West, but add: Love their city. Love it, love it, love it. Love it so much they will continue talking about it long after their companions have started piercing their own eardrums with drinking straws in a desperate attempt to escape. They believe they are not religious, but they are; they just substitute their city for God.
The Southwest: Very religious, very suspicious of outsiders, very… oh, hell, just take everything I wrote about the West and magnify it. Main city in this region, Stavanger, has become Norway’s oil capital and is now believed to be infested with Texans, who scare the locals.
Oslo and Environs: Yuppies and yuppie-wannabes. Obsessed with money. Not as sophisticated as they desperately believe they are. Ignorant of what’s going on in the rest of the country. Irreligious. City is infested with immigrants and their children, who smell bad, have too many kids, force their daughters to marry their cousins, eat weird food so hot it damages your innards, and are solely responsible for any increase in the crime rate… but damn, do they work cheap.
Rest of the Southeast: country hicks all over again. Kind of like the North, but without the reindeer. Also fewer sheep. Everyone is either a farmer or commutes to work in Oslo.
