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 123 m² (measured average in this buurt) with the average WOZ value here, €401,000.
Levies: Groningen'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.

Explanation
Crime is counted where it happens and divided by the number of residents, so places with many visitors — city centres, nightlife, stations — score higher.
The largest category in Oosterhaar is 'Theft and burglary': 4.0 per 1,000 residents in 2025, against 34.7 in the municipality of Groningen.

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.

Petrol76.5%

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'.
