Presentation: three research questionsPresentation: 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?
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

ConclusionsConclusions• 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
