neighbourhood in Alphen aan den Rijn
Biezen-West
2,210 residents · postal code 2771 · Part of Boskoop, Alphen aan den Rijn
Safe, but few children
Biezen-West scores a 10.0 for safety and that figure is earned right across the board: burglary, theft, vandalism and violence each lie far below the national middle, burglary at virtually zero.
The 7.5 for quiet & nature comes from two things: a low built density and a lot of open water — a sixth of the surface area. What does not help is the greenery, which is below the national middle, as is the tree canopy. This neighbourhood is quiet and spacious, but not wooded.
The families score stalls at a 5.9. The primary school is nine hundred metres away, and that is the heaviest item in that pillar; the share of children is also below the national picture. On wealth the picture is consistently favourable — property values above the median, a broad top income group, little social assistance — though at a 7.3 that score is less outspoken than safety here.

Frequently asked questions
Is Biezen-West a safe neighbourhood?
For 2025, Biezen-West comes out at 11 recorded crimes per 1,000 people present; the national middle is 24. That is low: Biezen-West 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 Biezen-West?
In Biezen-West the police recorded 25 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 Biezen-West calculated?
Biezen-West 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 Biezen-West 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.
