How comparisons work
Each search reads public sources for the home city, option 1, and option 2.
Live sources
- Weather
Open-Meteo
Monthly temperature and rain.
- Public indicators
World Bank
GDP per person, inflation, life expectancy.
- Currency conversion
Frankfurter
European Central Bank exchange rates, used only to change the currency of a money figure.
- Estimate
Google Gemini
When a key is configured, reads public pages such as Wikipedia, national statistics offices, WHO, and OECD.
Missing figures stay out
A row with no figure is left out. Nothing on this page is a fee or a quote.
Rows marked Estimate keep the page they came from. If that read fails, the rows are hidden and the other figures stay.
Information provided can vary by source.
