I will come to exit checks. The way in which advance passenger information data can be used to supplement and for support is important and I will address that directly. I highlight the fact that there are other sources of data. My hon. Friend may be aware of the workforce data survey and the use of the statistics for national insurance registrations. The IPS itself highlights and provides data in its reports and analysis in respect of different countries and provides separate analyses of where those flows come from, such as net migration from outside and from within the EU, and it produces the graphs that my hon. Friend has no doubt seen, tracking those back over 30 years. It gives a sense of long-term trends; it is important to understand where there may be growth in particular areas and what that might mean in terms of informing policy.
It is important to recognise some of the excellent and innovative research and analysis that has increased our knowledge of migration—for example, the migrant journey reports, the report on the social and public service impact of migration, and the recent report on labour market changes. All that work is critical in helping us to understand and appreciate the impact of migration on our country.
I highlighted the 2011 census, which provides extremely valuable data that has captured a much broader range of information on migrants than any census previously. The new census questions on the passports that people
hold and the length of time they have lived in the UK recognise the strong public concerns about immigration. We welcome that new statistical resource, which will go some way to meeting the Committee’s recommendation, but I will come to further refinements.
The Home Office has commissioned additional data to inform our understanding, such as a new question on emigration in the international passenger survey, the first results from which are now in the public domain, and a new question for the labour force survey on why foreign respondents had originally come to the UK. The breadth and depth of that work reinforces the fact that no single data source can provide a comprehensive picture of migration. That is why I also welcome the work in the UK statistical system to develop and enhance the range of sources, which together mean that we have a picture of migration that I believe is as good as that available to any other country across the globe.
I noted what the shadow Minister said about filling out the ESTA form and how that might be used. It is interesting to note that the US uses population surveys, not the ESTA system, to measure migration. It is important to recognise the interrelationship between the two, and that in some respects the information from e-Borders may help to supplement, but not replace, other information.
