Plenty of space, less prosperity
Kollum has two faces that lie far apart in the figures: an 8.1 for quiet and an 8.1 for families against a 3.3 for wealth. That last figure rests on all the components at once. The property value lies well over thirty per cent below the national middle, the share of households with a high income is almost halved compared with the national picture, and the social assistance density lies well above it.
With safety there is a detail that explains the figure. Clearly fewer offences are registered here than nationally, but violence lies above it — and that carries the most weight in that pillar. As a result it stops at a 7.2 rather than higher. On the quiet side the picture is more unambiguous: plenty of greenery, little noise and more surface water than usual.

Frequently asked questions
Is Kollum a safe neighbourhood?
For 2025, Kollum comes out at 18 recorded crimes per 1,000 people present; the national middle is 24. That is fewer than in most Dutch neighbourhoods. The figure is about what the police record, not about the people who live there.
How much crime is there in Kollum?
In Kollum the police recorded 120 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (18 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 Kollum calculated?
Kollum scores 6.7 as its total score. That grade is a national position: we weigh five equally heavy scores — safety, amenities, wealth & income, quiet & nature and families — and see where Kollum lands among every neighbourhood in the Netherlands. So it is not the mean of the five grades, but a place in the queue. All from open data published by CBS and the police.
