About
An independent tracker of Polish housing affordability
The Naprawdę Affordability Index is an independent, unsponsored data project — no ads, no paywall, no institutional funding. It's run by one person, but the code, raw inputs, and methodology are entirely public: anyone can check where every number comes from.
Independence
Where the data comes from, and whose money this is
We are not affiliated with GUS, NBP, any bank, or any developer. Every number comes solely from those institutions' public, free APIs — linked below and next to every section of the page.
The project takes no sponsorship or advertising. Upkeep (hosting, API calls) is privately funded. If that ever changes, it will be disclosed right here on this same page.
Corrections
Found a mistake? We want to know
Every number on this page traces back to a specific public source (see the methodology). If something doesn't add up — a calculation bug, a stale source, a typo — get in touch. Corrections are published openly in the methodology's changelog, never silently.
