Population, language, ethnicity and socio-economic aspects of education
Aims of the fellowshipAnalyse and map distribution of language across
LondonWhat issues does this raise?
Conduct some preliminary analysis between language and attainment
Analyse the relationship between language, ethnicity and socio-economic indicators
Provide guidance and training on the ways language data may be used with other data to answer social and educational research questions
A big issue in London
Updating Multilingual CapitalPublished in 2000, using pupil data from 1999 to identify and map languages in London
Pupil data 1999 2008
Pupils >850,000, attending state schools in London
>1,100,000, resident in London, attending a state school
Languages >350, including dialects and variants
322 categories collected, 239 without variants
Geography Boroughs mainly, some postcodes
Boroughs and MSOAs
Missing data Bromley and Havering did not collect data – synthetic data used
Variable data collection between schools and local authorities
But data collection variability makes comparison difficult…

local authority or across London, e.g.

Language classification
Geography• Percentage comparisons are problematic due to data capture variability
• Comparative counts of boroughs not suitable due to differences in size
• Wards and postcodes also differ in population size
•New statistical geographies - Super Output Areas

Choosing a scale
Equal counts
Aims for equal numbers of MSOAs in each category
Hides extreme values
Equal ranges
Aims to divide the whole range into equal segments
Extreme values dominate
Natural break
Elegantly captures both intensity and distribution
Complex mathematics not made explicit by MapInfo, and therefore difficult to explain to non-expert viewers
Quantiles (or in this case, Quintiles!)
Takes total count of pupils and creates target totals for each category – so each category has about 20% of all pupils
A compromise that captures intensity and distribution, relatively easy to explain
Patterns of clustering and dispersal

Language, ethnicity and attainment
How are ethnicity and language related? Can we create useful ethnicity/language categories?
How is language related to attainment? Does ethnicity/ language tell us more than ethnicity on its own?
