Chandon, I guess it depends on where you live? Dh did a full time Norwegian language course, and got to know lots of other foreigners. They were discussing friendliness and ease of integrating, and many said that it was harder around the capital than further north. He had no problems making friends with neighbours, and the dads taking their sons to football.
OP was asking about raising children. From that perspective it is good.
Maternity leave is either 10 months at full pay, or 12 months at 80% of full pay. You register your interest in a nursery at the birth of your baby. Children then start nursery at either 10 or 12 months when maternity leave ends. Paternity leave is one month full pay.
All nurseries are state subsidized, even private, or parent owned co-operative nurseries. The set fee nationally is £250 per month, and includes care from 7.30 till 5pm (when most people finish work, there are government guidelines that working hours should not be more than 35 hours per week), this includes lunch at 12 and snack at 3pm. Children bring packed breakfasts to the nursery, and eat together, getting juice and milk from the nursery.
The nursery had parents breakfasts, and "parties" such as St Lucia, Easter breakfast, Christmas party, Midsummer fest, Automn get to gether, along with carboot sales, and also there is the concept of dugnad, where all parents have to spend 15 hours of forced voluntary work at the premises, such as cleaning, raking leaves, painting playground equipment. These events were really popular as it brought parents together, and the community spirit was fantastic. The fees were kept low because everybody mucked in. The dugnad could also involve baking for occasions such as UN coffee morning, which was basically a fund raiser.
Both my kids are really happy and healthy and not to least outdoorsy after spending 3 years there.
However, there is a problem of how bullying is tackled in primary. It is all very wishy washy, and no real consequences, so no incentive for the kids to be nice to eachother.
(My problem, and one of the reasons we returned, was double taxation issues as we were, and are still, running a uk business)
