What Poland.gg Covers

Poland.gg is a free, interconnected data platform that aggregates publicly available Polish statistics, tools, and policy data into a single destination.

Administrative Geography

The site covers the full depth of Poland's administrative geography: from the country level down through 16 voivodeships, 380 powiats, and 2,477 gminas. All data is sourced from GUS (Central Statistical Office) and 100+ other public sources.

Statistics

Nine categories span population and demographics, fertility rates, housing market trends, unemployment, land use and territory, tourism, crime rates, marital status, and suicidal behaviours. Every data point is visualized with interactive time-series charts and color-coded choropleth maps, making it easy to spot regional patterns and compare municipalities at a glance.

Nine free tools cover three domains:

• ID and document validation: PESEL Checker, PESEL Generator, Polish ID Number Generator
• Business identifiers: NIP Checker, NIP Generator, REGON Checker, REGON Generator
