Polish Cities Experience Rapid Population Decline

Data from the Central Statistical Office (GUS) show that several Polish cities have been losing residents at an accelerating pace. Łódź’s population fell from about 854,000 in 2002 to roughly 655,000 in 2023 – a loss of nearly 200,000 people. Bytom dropped from around 190,000 to 150,000, and Wałbrzych shrank from about 129,000 to 100,000 in the same period. Similar declines are recorded in Sosnowiec, Zabrze and Częstochowa.

The shrinkage is driven by three overlapping forces: a negative natural increase, the out‑migration of young adults, and weak economic restructuring after the loss of traditional industry. While some central cities formally lose inhabitants, the functional metropolitan area may still grow as residents move to nearby suburbs such as Dopiewo, Kobierzyce or Żukowo around Poznań and Wrocław. This pattern of peripheral settlement contrasts with migration toward larger hubs like Warsaw, Kraków or abroad.
