Kollumerzwaag
2,800 residents · postal code 9298 · Part of Zuidwest, Noardeast-Fryslân
Plenty of space, less prosperity
Kollumerzwaag is quiet in a way that can be measured. Noise levels here sit far below the Dutch median, three quarters of the land in a three-hundred-metre radius is green, and population density is a fraction of a city neighbourhood's. Together that produces a 9.0 for quiet & nature.
The flip side is in the wealth figures, and they all point the same way. Property value sits far below the national middle, almost half of households fall in the lowest income group, high incomes are rare and the social assistance rate is more than three times the national one. Only vacancy is low. A 3.6 for wealth & income resting on a single outlier is common; this one rests on every component at once.
In practice, living here means the daily essentials are within walking distance — supermarket, GP and school all a few hundred metres away — but eating out is a drive of over three kilometres, and the station is further still.

Frequently asked questions

How much crime is there in Kollumerzwaag?
In Kollumerzwaag the police recorded 50 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (15 per 1,000) is not simply that count divided by the number of residents: we count residents plus workplaces, so a shopping street or station is not unfairly penalised, and for small counts we pull the figure towards the national average — otherwise a single incident would make a small neighbourhood look unsafe.
How is the grade for Kollumerzwaag calculated?

That grade is a national position: we weigh five equally heavy scores — safety, amenities, wealth & income, quiet & nature and families — and see where Kollumerzwaag lands among every neighbourhood in the Netherlands.
