What is Poland.gg?
Poland.gg is a free, open data platform covering Polish demographics, economics, housing, crime, tourism, and more. All of it sourced from GUS and 100+ other public datasets, all of it broken down across every administrative level: 16 voivodeships, 380 powiats, 2,477 gminas.
Time-series charts, comparative tables, choropleth maps. Pick a topic, pick a region, drill down as far as the data goes.
Tools
Nine interactive tools for the numbers and identifiers you actually run into living in Poland:
- PESEL Checker & Generator
- NIP Checker & Generator
- REGON Checker & Generator
- Polish ID Number Generator
- Mikrorachunek Generator & Checker
How it's built
Everything cross-references everything else. A voivodeship page links to its powiats, their gminas, the local crime stats, the housing data, the demographic trends. Articles about taxes connect to the tax policy pages and the calculators that use them. There's no dead-end page that dumps you back to the homepage.
Available in Polish and English.
