Everything close by, little space

Vandalism is the only offence type in Ouderzorg meaningfully above the national middle; violence and property offences both stay below it and burglary comes out slightly above. That explains why the safety pillar stalls at 6.7 while the total number of reports is below the median.

The wealth & income pillar does point consistently one way: the property value is above the national middle, the highest income group is broader than nationally and the lowest thinner, and vacancy is half the usual level. Only the social assistance rate is above the median.

The noise level is the weak spot. It comes out more than four decibels above the national middle, and that is more than the abundant open water nearby can offset. The GP is the exception in an otherwise short-distance neighbourhood: it is more than a kilometre away, while supermarket, school and restaurant are around the corner.

Frequently asked questions

Is Ouderzorg a safe neighbourhood?

For 2025, Ouderzorg 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 Ouderzorg?

In Ouderzorg the police recorded 93 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 Ouderzorg calculated?

Ouderzorg 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 Ouderzorg 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.
