Everything close by, except school and childcare
Leimuiden is thinly populated and green, and yet the quiet & nature pillar gets no further than a 5.8. The reason lies in one measurement: noise is six decibels above the national median, which counts just as heavily in this pillar as the greenery that sits well above it. The two cancel out.
The 8.8 for amenities is earned — shop, GP and restaurant are a few hundred metres away — but the primary school is further off, and because school distance is the heaviest component of the families pillar, that one stalls at a 3.9. Two pillars about distance, two very different outcomes.
Reported offences run slightly above the national middle. Of those only burglary is clearly elevated; violence, theft and vandalism stay below the median. That makes the 6.9 for safety a warning about home burglary rather than about the street.

Frequently asked questions
Is Leimuiden a safe neighbourhood?
For 2025, Leimuiden 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 Leimuiden?
In Leimuiden the police recorded 50 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 Leimuiden calculated?
Leimuiden scores 6.9 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 Leimuiden 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.
