Population/Demographic information Crime analysis, Poverty & deprivation Education Crime Visualisations mapping, dashboard Economics Evidence base for policy, strategy and service delivery 3. We need to talk about migration London is attractive to migrants Other parts of the UK European Union Commonwealth countries Elsewhere in the world Over 300 languages spoken London is a massive travel hub London home to many MNC Global trade and business connections ..London the World City 4. We need to talk about migration The driver of much demographic change in London. 30+% of Londons population is born oversees. Around 40+% of Londons working age population is born oversees. 56% of London births to mothers born outside the UK. (25% nationally) Considerable variation across London but nowhere is immune to the impacts of migration a better understanding is crucial 5. We need to talk about migration Most information from admin sources, surveys Definitions can vary (long term, short-term) Types of migrant vary Frequency of releases vary Data source not designed to capture migration primary Causes issues of interpretation Figures are different Misinformation, misinterpretation, misunderstandings 6. We need to talk about migration GLA primary interest Types of migrants; EU, economics migrants, Flows information: trends, changes in nature Migration by reason: work, study, other Population churn/turnover Migrant stock figures Migrant characteristics: education, employment, housing, length of stay etc Diversity issues Policy impacts ie visa rule changes, students Role of London in global migration issues. 7. Key Definitions Immigrant Person arriving to take up residence in a country for at least 12 months. Person with country of birth outside the UK. Person with nationality/citizenship of a country outside the UK. Emigrant Person leaving their usual country of residence to take up residence inanother country for at least 12 months. Migrant switcher Person who intended to stay in a country for at least 12 months but leftsooner. Visitor switcher Person who intended to stay in a country for less than 12 months but staylonger than a year. 8. Internal Migration Sources NHS Central Register (NHSCR) Patient Register Data Service (PRDS) Both act as a proxy to internal migration. Requires registration with a GP Reliable for the young and old need GP access. Less reliable for males aged 25-40 do not register/re-register. List inflation problematic for oversees emigration 9. London: Internal Migration TrendsNHS Central Register Inter-Regional Moves 10. International Migration Sources International Passenger Survey (IPS) Responsibility of Office for National Statistics voluntary survey of people arriving and departing from the fullset of ports and routes through/on which travellers can travelbetween the UK and overseas. The IPS is a continuous survey conducted 362 days a year. The survey has been conducted annually since 1961. Annual andquarterly publications have been produced since 1970 andmonthly since 1993. Monthly data from the IPS are published,but a single quarter is the minimum period over which detailedanalysis of the data can be made. 11. International Passenger Survey (IPS) Survey is intention basedthese can change. Excludes land routes between Ireland and the UK Excludes Asylum seekers and their dependent. Approximately 250,000 responding passengers per annum but only around 1-2% of these report intentions that comply with definitions of migrants. National Inflows for the 2004 statistics were based upon 2801 interviews andfor the outflow, on 755 interviews (standard error 4.7%). Disaggregate to countries and figures can be based on very low numbers ieestimate of a net 3,000 inflow from the Caribbean was based on thedifference between 28 interviews in and 6 interviews out. data can only be analysed and tabulated by very gross aggregated categoriesof (for example) country of origin and citizenship, purpose of visit, and broadage groups. Migration Statistics Improvement Programme has implemented improvements,boosting surveys at regional airports, using other data sources to sense checkIPS. 12. International Passenger Survey (IPS) Long Term International Migration (LTIM) Estimates produced by combining IPS, Home Office data onasylum seekers, migration to and from Northern Ireland andadjustment for visitor and migrant switchers. 13. International Migration Sourcescont Flag 4 International in-migrants who register with a NHS GP. Added to records mid-year to mid-year. Flag is lost once you move within the UK. National Insurance Number Registrations (NINos) NINos allocated to overseas nationals entering the UK. Limited country level details is available. Responsibility of DWP. Only newly issued numbers are recorded. 14. UK and London: International Migration TrendsLong Term International Migration (LTIM) 15.

Will provide count of residents and visitors in United Kingdom as at 27 March 2011. Main counts of migrants are derived from question on persons address one year before census day. Gives address in UK, or country in rest of world. Same question as 2001 but 2011 has specific tick box to identify student moves. 19. Spotlight on 2011 Census Also have Country of Birth question for persons not born in UK. This is as in 2001, 1991 and 1981. For 2011, additional question on time of most recent arrival in UK for these persons. can be used to derive the length of time in UK for internationalmigrants. Confusing if time spent in other countries. 20. Spotlight on 2011 Census New question on intention to stay for new migrants can determine if migrants are short-term (less than 6 months/6to 12 months) or long-term (one year or more). Household questions also identify visitors to the UK and UK residents who were temporarily outside UK on Census Day. 21. Spotlight on 2011 Census 2011 census also identified persons living at a second address for part of the year. Students at term time address v domicile address. Armed forces Boarders Can improve the quality of migration flows derived from census. 22. Strengths of Census Complete coverage of UK population. Ability to produce very detailed results: Very small local areas Detailed classifications eg country of birth based on write-inresponses Ability to cross tabulate by range of topics: eg migrants byhealth and disability Stable questions between censuses gives comparable figures over time. 23. and weaknesses Timeliness: main results from 2011 not expected until late 2012. Self completion. Frequency: snapshot once every ten years means some trends eg migration from A8 countries can be entirely missed. Acceptability: is census still the right way to collect data Future: ONS currently working on Beyond 2011 programme. 24. Use of Census data in GLA demography Themed Analysis Historical analysis Geographical Analysis Visualisations: Maps and themed dashboards. Some outputs will be specially commissioned specifically for London. Timing of these not yet known. Detailed statistics on origins and destinations of migrants will be produced later (probably some time in 2013) Detailed census migration counts used as starting point for GLA migration models. Breakdowns by age and sex, ethnic group and country or region of origin. 25. Publication of statistics from 2011 Census July 2012 head counts stats by LA. Univariate counts expected from late 2012 Counts of numbers of people/ households moving into and out of each area in the year before census day. Counts of students at term-time address For persons born outside UK: Country of Birth Year of arrival/age on arrival in UK 26. Spotlight on APS Annual Population Survey Introduced in 2004 Major survey which comprises key variables from the Labour Force Survey (LFS) The APS aims to provide enhanced annual data for UK, covering a target sample of at least 510 economically active persons for each Unitary Authority (UA)/Local Authority District (LAD) and at least 450 economically active persons in each Greater London Borough. 27. Spotlight on APS Indicators include: Age inc ages of dependent children Family unit and households inc dependents and relationships to HoH. Nationality and Country of Birth Length of stay inc separate responses for dependents and other householdmembers. Disability Ethnic group Health (current main and past problems) Qualifications, education and apprenticeships Industry Occupation 28.

Special license for APS from ESDS but restricted to approved researchers (approved by ONS) London specific analysis reported by GLA. 29. Births (1982-2010): England & Wales andLondon 30. Births by CoB of parent 56% of London births to mothers born outside the UK. (25% nationally) 42% of national births ot non UK born mothers are in London.
