Modeling internal migrations in Poland at municipality level

Data describing population migration in approx. 2,500 municipalities in Poland in the years 2003-2022. On this basis, models were built showing the most important causes and effects of these changes (Data_set03eng.xlsx). The second file (Result_errors_2003-2022.xlsx) presents error categories obtained using "pseudo k-means" classification method. The third file (travel_time_by_car.xlsx) contains data on travel times from all municipalities in Poland to their county capitals, subregionally important cities, and provincial capitals, used in modeling.
