It is increasingly important to have high quality statistics on migration and the population, for policy development and for planning and providing public services. Achieving this aim is challenging in the context of increasingly complex lifestyles and changes in migration to and from the UK over the last decade.
It has long been recognised that international migration is one of the most difficult components of population change to measure accurately. Large numbers of people travel into and out of the UK every year although migration numbers can be very different between one part of the country and another. There is no single, comprehensive source which can provide the information, at national and local levels, that is required for statistical purposes.
It is in the context of these pressures that the work of improving migration and population statistics has been prioritised. It is focussed on making improvements to the methods and data sources used to estimate the population at national and local levels during the inter-censal period. These improvements are needed to minimise the risk of divergence between the rolled forward mid-year population estimates and the 2011 Census-based population estimates, and to better understand the differences that remain.
The key strands of the Improving migration and population statitsics (IMPS) research are:
- migration research (both international and internal within the UK)
- collaborative work with local authorities to investigate the potential for making greater use of administrative data sources to improve local estimates
- population definitional issues
More information on the progress made on each of these strands of research is provided in the IMPS updates below.
In May 2006, ONS set up an Inter-Departmental Task Force on Migration Statistics with other government departments. The objective of the task force was to recommend timely improvements that could be made to estimates of migration and migrant populations in the United Kingdom, both nationally and at local level. The final report of the task force was published on 15 December 2006 and can be accessed from the 'Updates - December 2006' section below.
