Water board, maintenance and insurance are estimated from national rates and the home's value and size, so they aren't compared.
Explanation
The home: one typical home of 252 m² (measured average in this buurt) with the average WOZ value here, €623,000.
Levies: Zaanstad's own OZB, sewage and waste rates for 2026. The water board levy uses national average rates.
Set aside: maintenance at 0.85% and buildings insurance at 0.06% a year of the rebuild cost (€1,800 per m²).
NL median: what the same home would pay in the middle gemeente. Gemeenten where a regional body collects the waste levy are left out.
Not included: mortgage and energy. These are estimates, not actual bills.

02 · Safety
Too few residents for a rate per resident: these are counts.
Westerpolder has too few residents for a reliable rate per 1,000 residents (under 200), so counts are shown instead of a comparison. In 2025, 9 crimes were registered, against 2 in 2021. Crimes are counted where they happen, not where the offender lives.

Explanation
Too few residents for a reliable per-1,000 figure (threshold 200). Four categories are structurally withheld at buurt level (sex offences, child pornography, child prostitution, other integrity offences); the gap with the published total is shown under 'other'.
In 2024, police in Westerpolder registered 4 traffic accidents, of which 1 with injury and none fatal.

FatalInjuryMaterial damage only
Explanation
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.

Explanation
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.

Petrol69.2%
Other fuel (diesel, LPG, electric etc.)30.8%
Explanation
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 23% to 31% between 2024 and 2025.
