Nearly 56% of Poland’s GDP comes from Warsaw and four other regions

As much as 55.9% of the country's GDP is produced in the greater Warsaw area plus four other regions: Silesia, Greater Poland (Wielkopolska), Lower Silesia (Dolnośląskie) and Lesser Poland (Małopolska), according to GUS data.
Warsaw, the capital of Poland, is exerting significant economic dominance over the Mazovia region. With one-third of the population, Warsaw is home to almost 55% of all registered firms in the region. The city accounts for over 72% of the employed workforce in the enterprise sector in Mazovia. Additionally, Warsaw generates 17.5% of Poland's GDP, which is more than three times the rest of Mazovia and almost half of the industrialized Silesia region.
This pattern of metropolitan dominance is also observed in Pomerania, where the Tricity area represents nearly 50% of firms and employs two-thirds of the sector's workforce. Several other cities, including Krakow, Lodz, and Bialystok, demonstrate a similar trend of economic dominance in their respective regions.
