Real data,
not guesswork.
Liveability shows verified, address-level data on air quality, safety, walkability, and nearby amenities for Switzerland and the United States — pulled straight from official sources for the exact coordinates of the address you search.
The difference
Why not just ask AI?
General-purpose chatbots are great for a lot of things, but they're not built to give you live, verifiable, address-level data.
AI chatbots
- General knowledge, not tied to a specific address
- Training data can be outdated
- No source citations for specific numbers
- Can't be independently verified
Liveability
- Live data for the exact coordinates of your address
- Pulled from official sources in each country — Swiss federal offices (BAFU, swisstopo, FSO) and US agencies (EPA, Census Bureau, FEMA, FBI, HUD) — plus OpenStreetMap and Google
- Every number links back to its source
- Updated continuously
Methodology
How the data works
Each metric comes from a specific, named source.
In Switzerland
Air Quality
BAFU (Swiss Federal Office for the Environment) annual air pollution modeling — PM2.5, PM10, NO₂, and ozone — sampled at the exact coordinates of the searched address and compared against Swiss limit values.
Walkability & Amenities
Grocery stores, parks, schools, libraries, healthcare, dining, banks, places of worship, and parking are all community-mapped on OpenStreetMap and counted within the radius you choose.
Safety
Canton-level indicator from the Swiss Federal Statistical Office’s Police Crime Statistics (offences per 1,000 residents). Clearly labeled canton-level — Switzerland does not publish address-level crime data.
Local News
Recent headlines relevant to the area, pulled live via Google News for each search.
In the United States
US addresses use federal open data. Each card names its source and says whether it describes the address, the census tract, or a whole city or county.
Environment
Current air quality from AirNow and annual averages from the EPA Air Quality System; weather alerts and heat risk from the National Weather Service; modeled transportation noise from the Bureau of Transportation Statistics; sunlight from the National Laboratory of the Rockies (formerly NREL).
Getting around & daily life
EPA’s National Walkability Index; transit stops from OpenStreetMap and transit agencies from the Mobility Database; schools from NCES; grocery stores from OpenStreetMap with the USDA Food Access Research Atlas; county broadband availability from the FCC; health estimates from CDC PLACES and the CDC/ATSDR Social Vulnerability Index.
Safety, community & cost
FBI Crime Data Explorer rates for the city’s police department (or county sheriff) — clearly labeled city/agency level, not address level. Census ACS tract figures, Opportunity Atlas upward mobility, HUD Fair Market Rents, and a monthly budget from 2026 federal and state income tax rules.
Risks
FEMA flood zones and National Risk Index ratings (including wildfire), and EPA-listed Superfund, brownfield and toxic-release sites within a mile.
How scores are calculated
Swiss addresses
Amenity scores (grocery, transit, parks, schools, healthcare, dining, libraries, banks, worship, parking) are based on how many of each are found, and how close they are, within the radius you select. Where live Swiss departures are available, transit is scored on distance and departure frequency instead.
Air quality compares modeled pollutant concentrations (PM2.5, PM10, NO₂, ozone) against Swiss legal limit values — an index of 50 means pollution at the limit — and translates that into a score and category.
Safety score is inverse to the canton's offence rate per 1,000 residents in the FSO Police Crime Statistics — fewer offences means a higher score. It describes the whole canton, not the street.
Liveability Score is a weighted average of eleven metrics: air quality, walkability, grocery, transit, green space, schools, healthcare, dining, safety, sunlight and quiet, re-weighted over whichever have data. A natural hazard zone (−3 low, −8 medium, −15 high) or a contaminated site at or near the address lowers it.
US addresses
Liveability Score uses the same method and the Swiss weights for the eight metrics both countries share: air quality (EPA AQI), walkability (EPA National Walkability Index), grocery stores, transit, schools, safety (FBI rates for the city, not the street), sunlight and quiet, re-weighted over whichever have data. Green space, healthcare and dining aren't measured for US addresses yet. A FEMA high-risk flood zone (−8, or −15 on the coast) or a Superfund site within a quarter mile (−4) lowers the score.
Scores are a quick summary, but the underlying raw numbers — counts, distances, AQI readings, incident totals — are always visible and clickable for full detail.
Data freshness
Air quality (CH)
BAFU annual pollution modeling, updated yearly; Open-Meteo real-time data as fallback.
Crime data (CH)
FSO Police Crime Statistics, published annually (currently 2024 data).
OpenStreetMap amenities
Community-maintained, generally accurate but can lag for very recent openings or closures.
News
Pulled live every time you search.
Air & weather (US)
AirNow and NWS alerts are near real time; EPA annual air data, crime figures (FBI, latest full year) and Census ACS (5-year, latest release) update yearly.
Rent & tax (US)
HUD Fair Market Rents for the current federal fiscal year; federal and state income tax rules for 2026.
Privacy
Addresses you save are tied to your account only — they're never shared or sold. You can delete any saved address at any time.
FAQ
Switzerland and the United States. Swiss addresses use federal and cantonal open data; US addresses use federal sources such as the Census Bureau, EPA, FEMA, NWS, HUD, the FBI and the CDC, plus OpenStreetMap.
Yes. Searching addresses, comparing them, exploring areas, and saving addresses to your account are all free.
Every number comes from its named source at the time of your search, and each card says whether it describes the address, the neighbourhood (census tract) or a whole city or county. US crime figures, for example, are city/agency level, not address level.
No. It is an estimate from 2026 federal and state income tax rules, FICA and HUD Fair Market Rents, assuming wages only and the standard deduction. Local income taxes and pre-tax savings are not included. It is not tax or financial advice.
