Methodology and data sources
ZuriMap combines official public data, derived estimates and modelled lifestyle scores. This page makes those categories explicit so you can judge which signals are strong enough for your decision.
Three kinds of evidence
A published statistic, measurement or mapped feature from a public authority.
A calculation based on published data, such as a normalized density or estimated new-lease rent.
A 1–10 comparison created by weighting several source layers. Useful for ranking, but not a measured fact.
Core sources and transformations
Rent Official statistic + derived estimate
Quartier rent values use the City of Zurich's Mietpreiserhebung 2024. The headline value is the median net monthly rent for a 3.5-room apartment in the existing housing stock, excluding ancillary costs. ZuriMap's new-lease figures and rent-gap results are estimates derived from lease-age distributions; they are not advertised-listing prices.
Road noise Official geodata, summarized
The basis is the City's road-noise exposure register. Quartier values summarize daytime road-traffic exposure. Tram-only corridors, façade orientation, floor, windows and courtyards can make an individual home materially quieter or louder.
Safety Official district data + modelled score
The public basis is the police-recorded crime series for Zurich districts. ZuriMap's quartier-level 1–10 value is a comparative normalization, not a police rating or a prediction for an address. Police statistics cover reported and recorded incidents only.
Air quality Official measurements + modelled score
The City publishes daily NO₂, PM10, PM2.5 and other air-quality readings. Because monitoring stations do not measure every street, ZuriMap converts these measurements and spatial context into a relative quartier score.
Commute and access Estimated
Commute-to-HB values are directional estimates from representative quartier locations, including typical access and public-transport travel time. They are not live routing and do not account for a specific building, departure time, disruption or mobility needs.
Schools, parks and daily services Official points + OpenStreetMap
Schools, kindergartens, daycares, playgrounds, parks, badis, health facilities, recycling points and community centres are cached from the City of Zurich Open Data portal. Supermarket coverage uses OpenStreetMap. Density and proximity scores are derived from these point locations.
Population and quarter boundaries Official statistics
Population, international-resident share and geographic boundaries use City statistics and geodata. The City's Kreise und Quartiere page provides the official administrative context.
Overall and persona scores Modelled
Overall fit, family, budget, young-professional, nature and similar scores combine normalized source layers with explicit weights. They express a decision preference, not an official assessment. Your personalized score also depends on the goal, budget and anchors you enter.
Known limitations
- “Updated June 2026” is the ZuriMap snapshot date; every underlying dataset has its own measurement period and publication schedule.
- Rent statistics for existing leases can understate the price faced by a new tenant.
- Small-area and per-capita values can look extreme in central quarters with few residents.
- Scores are rounded and normalized for comparison; a one-point difference is not a guarantee of a noticeable real-world difference.
- For legal, health, safety or financial decisions, consult the primary source and an appropriate professional.
