Capturing linguistic diversityBy visualisation, with mappingUsing Simpson’s Diversity Index – a measure of richness and equitabilityThe formula for Simpson’s Index is: D =
where
D is Simpson's Diversity Index
S is the total number of languages speakers represented in a given area
P(i) is the size of the given language speakers as a proportion of the total population in the study area

Proof of conceptLanguage
PLASC is the only source of data for this but doesn’t cover all the population (excluded households without children in state schools)Partial data is available for most individual pupils without a specific language code Estimations of language spoken based on surname to be explored
EthnicityPLASC is also the best source for ethnicity, with patchy coverage in administrative data
