	Urban population of the Commonwealth was low compared to Western Europe. Exact numbers depend on calculation methods. According to one source, the urban population of the Commonwealth was about 20% of the total in the 17th century, compared to approximately 50% in the Netherlands and Italy ("Pic. 7"). Another source suggests much lower figures: 4–8% urban population in Poland, 34–39% in the Netherlands and 22–23% in Italy. The Commonwealth's preoccupation with agriculture, coupled with the szlachta's privileged position when compared to the bourgeoisie, resulted in a fairly slow process of urbanization and thus a rather slow development of industries.
