Social mobility refers to movement on different social positions, whereas spatial mobility refers to movement of people and goods in geographical space. Forms of spatial mobility are residential mobility (multilocal lifestyle, migration, relocation) and temporary migration as well as circular mobility (traffic, tourism, everyday routes). Questions of mobility are therefore linked to topics such as social and political participation or sustainable infrastructures.
