Answer:
the level of development depends on how financially the area is for example in cities ,the level of development is high compared to villages
this is because in cities there are many financial assets like jobs,industries,markets and others
increase in population also increases the level of development because there is large market for produced goods ,I mean in some places where there are lots of people , there is increased development..since the government sets up modern roads,high quality buildings,and others..that differentiates low populated areas from high populated areas
in industrious areas,there is high development because people are employed and they improve infrastructure for example building houses and also roads are developed since they need to transfer goods from industries
