This map allows you to look at proportions of ethnic minorities in schools along with the proportion in schools where their own ethnic group forms the majority at different geographical levels (wards, local authorities, regions, countries) and at different points in time.

You can also explore school segregation through some commonly used indices.
The index of dissimilarity is a measure of segregation that compares two separate groups. We have it mapped showing the level of segregation for an ethnic group relative to all other ethnic groups as well as the White British.

More specifically it is measuring the percentage of people within the ethnic group that would need to move to another area within the local authority in order to match the spread of the reference group. It ranges from 0 to 1 with higher values indicating greater segregation.

The index of isolation measures the probability that an individual selected at random will meet another individual at random who is like them within the local authority area in question (e.g. the probability that an Indian will meet another Indian). It ranges from 0 to 1 with higher values indicating a greater likelihood.

Regions are coloured according to quintiles. Darker shades represent a higher concentration of people within a particular economic category. To ease comparisons across time and ethnic groups, it is possible to lock the quintile distribution. Data are from the National Pupil Database.
