Everything close by, safety lags
A 8.9 for amenities alongside a 3.8 for safety: that is the tension in Zijlwatering-haven. The low figure hangs on the two components that together make up almost six tenths of that pillar. Violence occurs well over one and a half times as often as nationally and burglary more than double, while theft and vandalism simply lie at the national level. So no more disappears here than elsewhere; the difference lies in reported offences that have to do with people and homes.
The 4.9 for wealth is at least as remarkable, because the property value lies exactly at the national middle. That pillar is dragged down by the income side, where both the broad bottom group and the social assistance density come out above the national picture. The bricks are average here, the wallets are not.

Frequently asked questions
Is Zijlwatering-haven a safe neighbourhood?
For 2025, Zijlwatering-haven comes out at 28 recorded crimes per 1,000 people present; the national middle is 24. That is more than in most Dutch neighbourhoods. One caveat: the figure counts per person present, not per resident. In a neighbourhood with many visitors — a centre, a station, a shopping area — it therefore comes out higher than residents experience. The figure is about what the police record, not about the people who live there.
How much crime is there in Zijlwatering-haven?
In Zijlwatering-haven the police recorded 199 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (28 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 Zijlwatering-haven calculated?
Zijlwatering-haven scores 6.3 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 Zijlwatering-haven 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.
