In 2024, police in Westzaan registered 42 traffic accidents, of which 11 with injury and none fatal.
Registered accidents (BRON, Rijkswaterstaat); material-damage-only accidents have not been systematically registered since roughly 2010 and are not comparable between areas. This area shows only accidents with an exactly known location (roughly 80-85% of all registered accidents); the rest is known only at street, intersection or gemeente level. The comparison with the gemeente therefore also uses only the gemeente's exactly-located accidents, which is why that figure is lower than on the gemeente's own page.

47% of the area is green (parks, sport, nature), against 19% in the municipality of Zaanstad.
Every share is calculated as a percentage of the TOTAL area (land and water together, peiljaar 2022); water is therefore one of the slices itself, not a separate whole. Green is the sum of recreational terrain (parks, sport fields, allotments, day recreation) and natural terrain (forest, open natural terrain) — agricultural land is not counted as green here.

24% of passenger cars do not run on petrol (diesel, LPG, electric etc.), against 22% in the municipality of Zaanstad (2025).
CBS splits passenger cars into 'petrol' and 'other fuel' only. That second category bundles diesel, LPG, electric (including hybrid), hydrogen, alcohol, LNG and CNG together — CBS publishes no separate electric-car count per buurt, wijk or gemeente, so this is not the same as an 'electric share'.

The share of passenger cars not running on petrol went from 16% to 24% between 2014 and 2025.
See the 'Passenger cars by fuel type' card for what 'other fuel' covers — this is not the share of electric cars.
