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 their basis, models were built showing the most important causes and effects of these changes (Data_set03enf.xlsx). The second file (travel_time_by_car.xlsx) contains data about travel times from all municipalities in Poland to its county capitals, subregional important cities and capitals of provinces, used in modeling.
