1,980 residents · postal code 2191 · Part of De Zilk, Noordwijk
Safe, but not spacious
With a 9.9 for safety, De Zilk has one of the lowest crime figures in the country, and it holds on all four components: violence, burglary, property crime and vandalism are each below the national figure. Together with a 9.7 for amenities — everything within half a kilometre except the station — that carries the overall score.
The wealth & income pillar is the figure that needs most explaining. A 6.2 sounds middling, and it is: the share of high incomes sits exactly on the national median, property values barely above it and social assistance above it. So this neighbourhood is safe and well served without being affluent, a combination less obvious than it sounds.

Frequently asked questions
Is De Zilk a safe neighbourhood?
For 2025, De Zilk comes out at 11 recorded crimes per 1,000 people present; the national middle is 24. That is low: De Zilk is among the 20% of Dutch neighbourhoods with the fewest recorded crimes. The figure is about what the police record, not about the people who live there.
How much crime is there in De Zilk?
In De Zilk the police recorded 18 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (11 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 De Zilk calculated?
De Zilk scores 9.9 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 De Zilk 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.
