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 121 m² (estimated gemeente average) with the average WOZ value here, €438,000.
Levies: Teylingen'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.

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
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'.
