Safe, but everything is a drive away

Kolham has fewer than four hundred residents per square kilometre and still manages only a 4.7 for quiet & nature. That is the kind of score that calls for explanation, and it lies in the components: noise runs more than three decibels above the national median, greenery within three hundred metres below it, tree canopy too, and surface water is absent. Space alone does not make a place quiet.

Safety is the counterpoint at 9.7. All four categories sit below the median, burglary at a third of it, and the total stays well under the national middle. On amenities the bill is manageable: supermarket and GP are more than three kilometres off and the restaurant nearly as far, while the station at three kilometres is strikingly close for a village this far from the shop.

Frequently asked questions

Is Kolham a safe neighbourhood?

For 2025, Kolham comes out at 17 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 Kolham?

In Kolham the police recorded 23 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (17 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 Kolham calculated?

Kolham scores 5.1 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 Kolham 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.
