Spatial segregation index

Definitions

The segregation index suggested by Duncan and Duncan (1955) measures a group's distribution in spatial units and in theory ranges from 0 (perfectly equal distribution) to 1 (maximum segregation distribution). The index value shows the proportion of the group that would have to be moved to achieve perfectly equal distribution in the observed geographic area.

The political and administrative spatial sub-units on which the calculations are based are neighbourhoods in large towns and communes for cantons and larger urban zones.

The index is calculated as follows:

With ti = Total population in the spatial unit i; T = Total population in observed area: pi = proportion of group in spatial unit i; P = proportion of the group in observed area; xi = proportion of group X in spatial unit i; X = population from group X in observed area; n= Number of spatial units in observed area.

You can access the indicators in one of the following ways

All indicators

Some 68 indicators describe the current situation and changes in the integration of the population with a migration background and/or of foreign nationals in Switzerland in eleven areas of life in our society.

Key indicators

34 key indicators provide an overview of the progress made on the journey towards integration and the state of integration of the population with a migration background. If this information is lacking, the population is shown by nationality, and where this variable is available, the country of birth.
