1. INTERNAL MIGRATION BY ETHNICITY: A LONDON WARD-LEVEL STUDY John Stillwell School of Geography, University of Leeds, Leeds LS2 9JT Paper prepared for the UPTAP/BURISA Workshop on ‘Migration and Ethnicity’, City Hall, London, 26 September 2008

2. Presentation: three research questions How do migration propensities vary between ethnic groups in London and how does London compare with Britain as a whole? What spatial patterns of ethnic net migration are evident in London at the ward level and does the geographical variation tell us anything about processes of ethnic concentration or dispersal? Is there any evidence in London of ethnic groups moving away or towards areas of ethnic concentration and from areas of higher deprivation?

3. Data at ward scale Special Migration Statistics provide two tables on migrants: - Age by sex (Table MG201) - Ethnic group by sex (Table MG203) No breakdown of ethnic group by age Thus tables commissioned from ONS including: CO711: District-district matrix CO723: in two parts - Part 1: ward to region flows - Part 2: region to ward flows both for 7 age groups (0-15, 16-19, 20-24, 25-29, 30-44, 45-59, 60+) for 7 ethnic groups

4. Ethnic groups used in study Label used in paper Ethnic group defined in Special Migration Statistics (Level 1) Ethnic group defined in Key Statistics White White British; White Irish; Other White Indian POSAPakistani and Other South Asian Pakistani; Bangladeshi; Other Asian Chinese BlackCaribbean, African, Black British and Black Other Caribbean; African; Other Black Mixed White and Black Caribbean; White and Black African; White and Asian; Other mixed Other

38. Conclusions There are significant variations in migration propensities by ethnic group and age but also for within, into and out of London migrants Decomposing net migration balances into flows ‘within’ and ‘outside’ London exposes key processes of suburban decentralisation, outward dispersal and inward concentration Non-white migration dispersing rather than concentrating non-white populations and all ethnic groups are moving from more deprived to less deprived areas
