Spacious and quiet, but not set up for children
Above De Leijen stands almost four times as much tree canopy as above the average Dutch neighbourhood, and that shows in the 7.6 for quiet & nature — striking for a neighbourhood where the density is by no means low. Greenery and noise work the same way.
The 5.2 for families has two causes that reinforce each other. The primary school is a good kilometre away, and on top of that the population is strongly ageing and there are few households with children living in them.
The safety score of 5.6 is one to read carefully. The total number of registrations lies almost exactly at the national average and violence even stays below it, but burglary comes out at more than double the median — and after violence that is the component that counts hardest.

Frequently asked questions
Is De Leijen a safe neighbourhood?
For 2025, De Leijen comes out at 24 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 De Leijen?
In De Leijen the police recorded 149 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (24 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 Leijen calculated?
De Leijen scores 6.8 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 Leijen 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.
