Spacious and quiet, but not set up for children

One in nine homes in Kollenberg-Park Leyenbroek stands vacant, almost three times the national share — and that is the only component on which this neighbourhood lags. Property value is above the median, the area counts considerably more households on a high income than nationally and social assistance is barely more common. So the 6.8 for wealth & income is not mediocrity but an average of extremes.

The rest of the picture is that of a spacious, ageing neighbourhood: more than a third of residents are 65 or over, the tree canopy is twice as dense as nationally and noise is three decibels below the median. Hence the 8.7 for quiet & nature. The 5.6 for families fits with that — the school is close by, but few children live here.

Frequently asked questions

Is Kollenberg-Park Leyenbroek a safe neighbourhood?

For 2025, Kollenberg-Park Leyenbroek comes out at 21 recorded crimes per 1,000 people present; the national middle is 24. That is fewer than in most Dutch neighbourhoods. The figure is about what the police record, not about the people who live there.

How much crime is there in Kollenberg-Park Leyenbroek?

In Kollenberg-Park Leyenbroek the police recorded 97 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (21 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 Kollenberg-Park Leyenbroek calculated?

Kollenberg-Park Leyenbroek scores 8.6 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 Kollenberg-Park Leyenbroek 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.
