Everything close by, safety lags
Burglary is the figure that stands out in Rockanje: a good three times the national median, while property crime stays far below it. That is an unusual balance, and it is the main reason the safety pillar stalls at 4.7 despite a total of reported offences below the national median.
The population is old: a third of residents are 65 or over and almost half of households consist of one person. The families pillar therefore comes out at 4.9, even though school, shop and GP are all a few hundred metres away — here it is not distance but composition that makes the score.
The quiet & nature pillar reaches 7.8, with a tree canopy well above the national median and noise levels below it.

Frequently asked questions
Is Rockanje a safe neighbourhood?
For 2025, Rockanje 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 Rockanje?
In Rockanje the police recorded 44 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 Rockanje calculated?
Rockanje scores 6.0 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 Rockanje 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.
