2. Project Aims
To project the ethnic populations of local areas in the UK over the next 50 years
To develop estimates of the inputs to the projection for the current decade
Presentation Outline
To explain the model design being developed (Phil Rees)
State space of model
Accounting framework
Model structure
Internal migration model
Ethnic mortality estimation (Phil Rees)
Ethnic fertility estimation (Paul Norman)
New Migrant Databank (Pete Boden)
6. Population accounting framework for countries and local authorities
8. Internal migration model
Something between a rock (saturated)
O432 D432 E18 S2 A102
and a hard place (independence)
O432 + D432 + E18 + S2 +A102
such as
A102S2 + O432D432E7 + E18
age-sex + origin-age, origin-destination-broad ethnicity + detailed ethnicity
9. Ethnic mortality: proposed estimation method
LA life tables and LA SMRs for whole population
2001 Census SIRS for whole population
Compute SMR = ac + bc SIR for c=England, Wales, Scotland and Northern Ireland LAs
2001 Census SIRs for ethnic groups for Las
2001 ethnic SMRe = ac + bc SIRe
dea (1) = d*a SMRe /100
dea (2) = dea (1) × [D*a /Se dea (1)Pea ]
14. International Migration
15. Context: Complexity
16. Context: Uncertainty
17. Context: Conceptual differences
18. Context: Alternative sources
19. Context: ONS developments Improving Migration and Population Statistics (IMPS) project
NSQR of international migration
improving both the estimation of total migration flows to and from the UK,
improving the allocation of international migration to local areas.
Short-term migration estimates
Evaluation of alternative administrative sources
20. This Research Project: Objectives International Migration estimates for the new Ethnic Population projection model
New Migrant Databank (NMD)
alternative sources
local authority level
available, accessible data
integrated view
improved estimation (level & distribution)
21. This Research Project: Data Sources Census
Total International Migration (TIM)
International Passenger Survey (IPS)
National Insurance Number (NINo) statistics
Workers Registration Scheme (WRS)
GP Registrations (Flag 4)
Higher Education Statistics Agency (HESA)
National Pupil Database (NPD)
Labour Force Survey (LFS)
22. This Research Project: Progress
23. We have been working on/will work on:
Model design/program writing
Initial database/completion and harmonisation
Ethnic mortality/full implementation
New migrant database/integration and synthesis
Ethnic fertility/use of GHS and LS
