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 survey + derived estimates
Guide and map rent references use the 2024 City of Zürich survey: 3-room private rentals, net monthly rent, existing leases of all ages. Some quarters share the same survey area. The address brief allows 2-, 3- and 4-room groups. Estimated new-lease figures model lease-age differences; they are not live asking rents. Original survey.
Road noise Legacy editorial estimate · unverified
The stored area values have no reproducible source transformation in this release. They must not be read as current official measurements or predictions for a specific home. Scores using them inherit this limitation. Check the exact address and current primary data before relying on them.
Safety Legacy editorial estimate · unverified
The stored area values have no reproducible source transformation in this release. They must not be read as current official measurements or predictions for a specific home. Scores using them inherit this limitation. Check the exact address and current primary data before relying on them.
Air quality Legacy editorial estimate · unverified

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. The location score uses Overall priorities by default. You can choose another priority in Settings; your choice is saved on this device and applies across addresses. Affordability compares modeled area rents across Zürich. Personal rent budgets and apartment asking rents do not affect the location score.
Estimated summer comfort · beta
The address brief and comparison show three relative overheating levels for matched buildings: more prone, typical for Zürich, or less prone. Ratings compare modelled buildings in a fixed August 2023 weather test without active cooling. Even a relatively better building can overheat. Results are automatic, uncalibrated estimates with low confidence; the displayed scenario range is not a statistical confidence interval. No indoor temperatures are measured and apartment details do not change these precomputed ratings.

Known limitations
- “Updated September 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.
