Last year the commune1 check-in changed 455.899 people. Invariably for years, most of these movers — 71.4% — are local movers, up to 50 km (including 57.5% to 25 km). They are mainly those who have married and moved in with their spouse or spouse, or families who have built a home outside the city and moved in with him.
It's more interesting if we look at another moves. Let's start with a map of the movers 100 km distant from the erstwhile municipality. The darker the colour, the more people moving out of the municipality moved far beyond their household region.
Here we see fascinating regional differences:
Residents of western Poland, with a fewer exceptions specified as Sudety, Lubuskie Voivodeship and Central Pomerania, seldom decision far from home. In particular, Wielkopolska and Kaszuba are seen, where it is hard to find a commune where more than 10% of those moving out of the region.
Conversely, it is in east Poland. In a immense number of municipalities, as many as 1 in 4 moving out of the household region. The exception is the area between 50-100 km from Warsaw, the Lesser Poland Voivodeship, and – a bit more in a grate – the gminas in Podlaskie Voivodeship.
It's interesting in large cities. Their residents are in the mediate – they are more likely to go to a completely fresh region than the inhabitants of western Poland, but much little than east Poland
In my opinion, the possible explanation of these results comes from itself. Western Poland is more developed and urbanized — even in smaller cities residents can find work in various factories, service facilities, offices or public establishments specified as hospitals or schools, and there are at least any basic entertainments after work. Even if specified opportunities are not available in a given municipality, a dense network of tiny and medium-sized cities allows regular commutes to work. These opportunities keep more people in place than in east Poland, where agrarian strict areas prevail, towns are few, and those that are are frequently very tiny — small larger than the countryside.
But this explanation raises the question — why is the percent of people moving out in large cities in the west higher? Why, proportionally, outside of Wielkopolska are more people moving out of Poznań than Leszna?
I think there are 2 answers. First, if people from the state are coming to these cities, any of them will always return to that province, whether to marry or to be tired of a large city or to retire. The second clue suggests a different map — here we see the provincial city, to which the most people from a given municipality (marked in colour) have left, as well as the number of people travelling to that city (marked in the size of a dot).
