Title: Michelle vonAhn, Ruth Lupton and Dick Wiggins


1
Population, language, ethnicity and
socio-economic aspects of education
  • Michelle vonAhn, Ruth Lupton and Dick Wiggins

2
Aims of the fellowship
  • Analyse and map distribution of language across
    London
  • What 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

3
A big issue in London
4
Updating Multilingual Capital
Published in 2000, using pupil data from 1999 to
identify and map languages in London
5
Pupil data
But data collection variability makes comparison
difficult
6
Language data ambiguity
7
Ambiguous language
8
Data inconsistency
  • Some languages have variants, which are not
    consistently used within a local authority or
    across London, e.g.

Language classification
10
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
16
Equal counts
  • Aims for equal numbers of MSOAs in each category
  • Hides extreme values

17
Equal ranges
  • Aims to divide the whole range into equal
    segments
  • Extreme values dominate

18
Natural break
  • Elegantly captures both intensity and
    distribution
  • Complex mathematics not made explicit by MapInfo,
    and therefore difficult to explain to non-expert
    viewers

19
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

31
Migration patterns over time
  • Annual data could show change (if data is
    collected in a robust way)
  • Established or magnet communities
  • Recent arrivals

32
Turkish, 1999
33
Turkish

36
Lithuanian

37
Somali
London 27,126
38
Somali numbers have increased, but their
distribution has also become more dispersed
39
Language is not always enough
  • French speakers
  • 17 White
  • 57 Black
  • 26 Other
  • Arabic speakers
  • 57 Other
  • 15 Black
  • 10 Mixed
  • 9 White
  • 8 Asian
  • Spanish speakers
  • 35 White
  • 4 Black
  • 61 Other
  • Portuguese speakers
  • 54 White
  • 19 Black
  • 27 Other

40
French by ethnic group
London 13,020
41
French has an east-west distribution by ethnic
group
smaller numbers
42
Spanish by ethnic group
London 8,647
43
White Spanish speakers are more likely to be from
Europe, while Other Spanish are probably from
Central and Latin America
44
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?

45
Average points at Key Stage 2 by Ethnic Group

Linguistic Breakdown for Selected Lower Attaining
Groups

White other
48
Diversity in the Black African group
  • Lower attaining
  • Higher attaining

Igbo

51
Akan/Twi/Fante
London 8,117
52
Diversity in the white other group
  • Higher attaining
  • Lower attaining

53
Next stages
  • How are ethnicity/language categories related to
    socio-economic status?
  • Explore FSM, IDACI, using London ASC
  • Matching to local authority data (e.g. housing
    benefits, Council tax band), for a case study
    borough (Newham)
  • How is the attainment of ethno-linguistic groups
    related to indicators of socio-economic status?

Consultation
  • Local authority views of the practical, legal,
    technical and ethical issues for data matching
    within and across authorities
  • Identifying practical uses of matched data
  • Goal to prepare guidance for other data users
