The home: one typical home of 192 m² (measured average in this buurt) with the average WOZ value here, €711,000.
Levies: Stichtse Vecht'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.

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.

Passenger cars by fuel type
28% of passenger cars do not run on petrol (diesel, LPG, electric etc.), against 26% in the municipality of Stichtse Vecht (2025).
Petrol72%
Other fuel (diesel, LPG, electric etc.)28%
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'.
Source: CBS Kerncijfers wijken en buurten (KWB) 2025
Share on other fuel per year
The share of passenger cars not running on petrol went from 28% to 28% between 2021 and 2025.
See the 'Passenger cars by fuel type' card for what 'other fuel' covers — this is not the share of electric cars.
