Presentation Presentation Presentation Presentation • Brief context Brief context • Aims and data used • Ethnic migration at national level: flows and rates Ethnic migration at national level: flows and rates • Ethnic migration at district level: churn, effectiveness and spatial connectivity y • Distance moved and the effect of distance on migration within London • Ethnic migration at ward level outside London : patterns of net migration by population concentration and by level of deprivation concentration and by level of deprivation • Conclusions
Brief context • Plenty of attention has been paid to migration in l last few years t f • Over 6 million people moved usual residence within Britain in 2000-01, of which less than 10% i 2000 01 f hi h l th 10% ithi B it i were non-white ethnic minorities • Increasing number of research studies of ethnic I i b f h t di f th i internal migration: Champion (2005), Stillwell and Duke Williams (2005) Finney and Simpson and Duke-Williams (2005), Finney and Simpson (2008, 2009), Simpson and Finney (2008, 2009), Stillwell et al (2008) Stillwell and Hussain Stillwell et al.

OUR AIMS • To show ethnic and age variation in migration propensities and that non-white migration remains concentrated in certain (urban) parts of the GB • To explore how effective net migration has been in p g distributing ethnic populations across GB • To examine differences in spatial connectivity by To examine differences in spatial connectivity by ethnic group – GB and within London • To assess how the frictional effect of distance varies • To assess how the frictional effect of distance varies by ethnic group – model inter-borough flows within London since inter district matrix is very sparse London since inter-district matrix is very sparse • To examine the relationship at ward level outside L London between net migration and (i) ethnic d b t t i ti d (i) th i population concentration and (ii) deprivation
Firstly…… something about data Firstly…… something about data • All data used come from 2001 Census and refer to the 2000-01 period (12 months before the Census) • Special Migration Statistics provide: - Migrants by age by sex (Table MG201) Migrants by age by sex (Table MG201) - Migrants by ethnic group by sex (Table MG203) i.e. no breakdown of migrants by ethnicity and age i b kd f i t b th i it d • Commissioned tables from ONS: CO711: District to district flows CO723: Part 1: ward to region flows P Part 2: region to ward flows t 2 i t d fl disaggregated by 7 age groups (0-15, 16-19, 20-24, 25-29, 30-44 45-59 60+) and 7 ethnic groups 30 44, 45 59, 60+) and 7 ethnic groups
