avg i think it's about 40k but most families both parents work.
avg home in and around a big city 400k but greatly dependend on the neighbourhood, if you don't mind all your neighbours named muhammed you can get a house a lot cheaper.
Maybe I should become a RichAmerican too.
I live in Copenhagen.
If you own your home, the average price per m2 (square meter) is 52435 dkr = about 7000 Euros.
I live in a fairly average apartment at 86 m2 = 600000 Euros
But i only own a share of the building (andelsboligforening) and would only be able to sell it for 200-250000 euros.
Average income (all ages, even kids) in my area is 45000 Euros/year before taxes.
For all of Denmark it´s 40000.
