In 2024, police in Noordpolder registered 1 traffic accidents, of which 0 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.

14% of the area is green (parks, sport, nature), against 8% in the municipality of Alphen aan den Rijn.
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.

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'.
