  1. INTERNAL MIGRATION BY ETHNICITY: A LONDON WARD-LEVEL STUDYJohn Stillwell School of Geography, University of Leeds, Leeds LS2 9JTPaper 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

  5. Example of the commissioned data: Table CO723 Part 1

  6. How consistent are the commissioned data for flows between wards within London?

  7. London’s ethnic population, 2001 * Index of segregation = 0.5 ∑|Pie/P*e- Pir/P*r| computed at district level

  8. Non-white populations, 2001 GB London

  9. London’s ethnic population by borough, 2001

  10. White location quotients, London wards, 2001 Location quotient = (Pie/Pi)/(Pe/P**) >1 is over-representation

  11. Non-white location quotients, London wards, 2001 Indian POSA Chinese Black Mixed Other

  12. Mean location quotients of ethnic groups by quintile

  13. London’s ethnic migration, 2000-01 * Average of the inflows and outflows from Table C0723

  14. How consistent are CO723 with SMS net flows between London and the rest of England and Wales?

  15. London’s gross and net migration by ethnic group, 2000-01

  16. Intra- and inter-district flows in GB and London, 2000-01 GB London

  17. London’s white inflows and outflows by age, 2000-01

  18. London’s non-white inflows and outflows by age, 2000-01 INFLOWS OUTFLOWS

  19. Migration rates, 2000-01 Inflow, outflow and net flow rates are between London boroughs and rest of GB

  20. Age-specific migration rates, 2000-01 Within London Within GB

  21. Flows within London by age and ethnic group, 2000-01

  22. Migration rates into and out of London, 2000-01 Rates into London Rates out of London

  23. Flows between London and the rest of GB Inflows to London Outflows from London

  24. London’s migration at ward level 628 wards

  25. Net migration by ward, whites, based on flows within Greater London

  26. White net migration by ward, based on flows with the rest of England and Wales

  27. White immigrants by London ward

  28. Patterns on non-white net migration within London Indian POSA Chinese Black Mixed Other

  29. Within London >60 20-24 Outside London >60 20-24

  30. Within London >60 20-24 Outside London 20-24 >60

  31. Immigrants by London ward in 2000-01 Indian POSA Chinese Black Mixed Other

  32. Net migration rate by ethnic group and location quotient quintile Quintile 1 Quintile 5 High location quotient/ Low location quotient/ Over-representation Under-representation

  33. Townsend index for London wards Quintile 1: least deprived Quintile 5: most deprived

  34. Net migration by ethnic group and deprivation quintile

  35. Net migration rate by ethnic group and deprivation quintile

  36. Age-specific ethnic group net migration rates by deprivation quintile

  37. Age-specific ethnic group net migration rates by deprivation quintile

  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
