Everything for children close by, and little room
Burglary is virtually absent in Nieuwe Sloot and property crime is at less than half the national median, but vandalism occurs more than twice as often. That mixture keeps the safety pillar at a 6.8.
The primary school is a good kilometre away, and that is the immediate brake on the families pillar: it still reaches a solid 8.1, carried by the high share of children, but distance weighs the most there and comes out unfavourably here. Quiet & nature gets no further than a 4.3 — there is plenty of open water, but little greenery nearby and noise is above the median. Wealth & income is average at a 6.2: top incomes well above the national figure, property value slightly below it, social assistance slightly above.

Frequently asked questions
Is Nieuwe Sloot a safe neighbourhood?
For 2025, Nieuwe Sloot comes out at 26 recorded crimes per 1,000 people present; the national middle is 24. That is about the same as in an average Dutch neighbourhood. The figure is about what the police record, not about the people who live there.
How much crime is there in Nieuwe Sloot?
In Nieuwe Sloot the police recorded 60 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (26 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 Nieuwe Sloot calculated?
Nieuwe Sloot scores 7.7 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 Nieuwe Sloot 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.
