neighbourhood in Heiloo
Oosterzij
2,145 residents · postal code 1851 · Part of Ypestein, Heiloo
Safe, but few children
At 9.8, Oosterzij belongs to the four hundred highest-scoring neighbourhoods in the Netherlands, and the safety score contributes most to that. Of the four measured offence types not one sits above the national middle; vandalism and burglary occur four to six times less often.
The wealth & income pillar points the same way, with a property value more than a quarter above the median and a social assistance rate around the national one.
The 6.4 for families stands out among them. The primary school is seven hundred metres away, so distance does not explain it — the share of children under fifteen stays below the national figure here, and that component counts in this pillar alongside the distances. That the score looks low next to the rest of the page says more about the rest than about this neighbourhood.

Frequently asked questions
Is Oosterzij a safe neighbourhood?
For 2025, Oosterzij comes out at 11 recorded crimes per 1,000 people present; the national middle is 24. That is low: Oosterzij is among the 20% of Dutch neighbourhoods with the fewest recorded crimes. The figure is about what the police record, not about the people who live there.
How much crime is there in Oosterzij?
In Oosterzij the police recorded 24 crimes in 2025: theft, burglary, violence and vandalism combined. The comparison figure above (11 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 Oosterzij calculated?
Oosterzij scores 9.8 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 Oosterzij 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.
