Migration Statistics

Debate between Bernard Jenkin and Keith Vaz

Thursday 26th June 2014 Westminster Hall

[Mr Jenkin]

My hon. Friend highlights the complexity of moving purely to a counting in and counting out system. Only two countries in the world base their immigration and emigration estimates entirely on counting. One is Australia, which is a good example. A less encouraging example is North Korea. However, every other country in the world bases its migration flow estimates on samples, measuring and estimating or a population register. Germany, for example, keeps an up-to-date population register—the equivalent of a census kept constantly up to date—to monitor its migration flows.

We are in a no man’s land at the moment. We neither count effectively nor sample effectively, and even though we have the decennial census, which has provided the correction of 346,000, that does not resolve the problem between censuses. The underestimation of net migration was identified only by the census on a 10-yearly basis, so the ONS is unable to revise its annual estimates of immigration and emigration as components of migration during the same period, even though it knows that they must be wrong. As a result, for the years from 2001 to 2011, our best estimate of net migration each year is not equal to our best estimate of immigration minus our best estimate of emigration. We are into an Alice in Wonderland world of numbers in which we know that our official figures for each year are wrong, but they cannot be changed, as we have no other sources to use.

In all probability, the actual population of the country will be even larger than that recorded in the census. Many people in the country do not consider themselves to be “residents” and thus decide not to complete the census form. Many others, who have overstayed or are in the country illegally for other reasons, are most unlikely to complete the form. Immigration will thus have been even higher in the last decade than was estimated by the census.

The PASC concluded that the UK’s immigration statistics are not fit for purpose. There was some pushback from the Home Office in reaction to our report last summer, but I think we have to regard that as a natural reaction of denial about the failure of the system of immigration statistics that has been building up for decades. The UK Statistics Authority agrees with us in that respect, saying in its response to our report:

“The limitations of the International Passenger Survey (IPS) in particular and UK international migration statistics in general, especially for local areas, have long been known and debated. The Statistics Authority believes that action must now be taken to address this.”

As I mentioned, when we look at smaller groupings within the 3,000 immigrants identified, such as immigrants from the EU or from specific countries, the system becomes even less reliable, as the 95% confidence interval becomes larger relative to the size of the sample, eventually becoming larger than the sample itself.

I give way to the Chairman of the Select Committee on Home Affairs.

[Keith Vaz]

I am sorry that I missed the opening remarks of the hon. Gentleman’s very important speech. May I say how pleased I was, and the Home Affairs Committee was, to know that his Committee had undertaken such a thorough examination? One of the big problems has been the absence of a resolution of the issues relating to the e-Borders programme, which was promised to be the best and most effective way of counting people in and out. Does the hon. Gentleman share my concern that, years after that programme was introduced and then closed, there is still no resolution of the problem relating to e-Borders?

[Mr Jenkin]

I do share that concern, but if the right hon. Gentleman will forgive me, I will deal with that issue later.

I was talking about the 95% confidence interval in respect of smaller samples relating to individual countries. The ONS will publish estimates of immigrants by country only for the top 15 source countries, because for all the other countries the sample is too small to provide a meaningful estimate—in other words, the number of people from Iran or Afghanistan is actually smaller than the 95% confidence interval itself, so the number is meaningless.

We have vague estimates of the numbers coming in from China, India, Poland, the USA, Australia, Spain, Pakistan, France, Germany, Italy, Canada, Nigeria, New Zealand, Lithuania and Hong Kong. Those are the countries for which figures are published. For the other 180 or so countries, no figures are published, so we cannot tell from the data how many Russians, Iranians, South Africans or Romanians are coming to this country.

For the same reason, the ONS migration data cannot provide anything meaningful for local authorities that are trying to work out how migration flows affect their area or to plan for population changes. The UK Statistics Authority also stated:

“The IPS sample size is too small to enable the production of reliable international migration estimates at a local authority level, and cannot realistically be made sufficiently large to achieve robust local estimates.”

The census, which is designed to count every member of the population, provides the only reliable data on the number and characteristics of migrants at local level, but we get it only every 10 years, which is why it was so full of surprises.

In evidence to us, Westminster city council said that the current methodology for estimating migration was not robust enough to support accurate local-level estimates, so that

“the measurement of migration from the perspective of an LA user and as reliable information on our residents is failing”.

The leader of Westminster more or less told us that the only way it can find out the nationalities of the people in the borough is to go around and count them itself. That may be a responsibility that it should take on, but—[Interruption.]

--- Later in debate ---

[Keith Vaz (Leicester East) (Lab)]

It is a pleasure to serve under your chairmanship of this important debate, Mr Walker. I did not plan to speak, but I will say a few words in support of the excellent report published by the Public Administration Committee. Those of us who sit on the Home Affairs Committee welcome the fact that other Committees are interested in migration issues. I am not in any way parochial, and I do not believe that there are bits of Government that should be reserved only for one Select Committee or another. Such oversight is a core function of the Public Administration Committee, which is so ably led by the hon. Member for Harwich and North Essex (Mr Jenkin). The Committee has produced a brilliant report that will help not only the Home Affairs Committee but other Select Committees that cover immigration policy, either directly or indirectly.

I will say a couple of things about the importance of accurate statistics. The hon. Gentleman is right that there will be a great deal of debate about immigration in the run-up to the next general election. We are in the odd situation of knowing the date of the general election. Subject to any changes that might occur in the coalition Government over the next few months, we know when the general election will take place and we know—one does not have to be a genius to know this—that immigration will probably be in the top three issues of concern to the British people. That is why it is so important that we have accurate information when immigration is debated in this House, and when it is debated outside by others who represent parties unable to get elected to this House. That is why the report is not only important but timely.

As the House goes on the slow journey to recess, some of us may choose to go abroad for a holiday—depending, of course, on whether our passports have been renewed. We will be watching and observing the “exit strategy” when we get to the airport. It has always been a mystery to me why we have to go through the great drama of supplying passport information and accurate information about our names, so that they do not differ in any way from our passports, prior to departure, yet after people check in and walk past the last person before getting to security, their passports do not really get checked.

I know that the Government’s commitment, which I am sure the Minister will reaffirm, is to have full exit checks by the time of the general election, so that by May 2015, we will have counted everyone out. However, I still do not understand why it is not possible, even at that stage—after checking in and walking past the last person before security—for the officers at Heathrow airport to check a passport on departure. After all, it is not a question of queues. I do not think any special arrangements are made for me or other members of the Home Affairs Committee—people may say, “If not, why not?”—but when I travel through Heathrow, I do not see many queues building up at the point where people show their tickets, walk through and get a little plastic bag to put in their liquids. There are queues before check-in—there is no doubt about that—and there are queues at security. There is an excellent opportunity to glance at people’s passports as they wait to go through security, because there are always queues there, whatever channel they go through.

[Mr Jenkin]

That is an interesting observation. The task of checking people’s luggage and what liquids they are carrying is far more complicated physically than checking passports or tickets or checking people in. However, where there has been a real will to try to reduce that anxious and tiresome part of the journey for passengers, great strides have been made in making a very painful process tolerable for passengers. Does that not show that where there is will, there is a way? We could get far more data from passengers as they go through ports of entry.

[Keith Vaz]

Absolutely. I agree with the hon. Gentleman: of course it can be done. It is an easy win for this Minister, who is a hard-working Minister—I think he has now been in the House three times this week and there is another Adjournment debate before six o’clock; I do not know whether he knew that. It is an easy win for him to announce this change. It needs the co-operation of security staff at Heathrow airport, of course, as well as that of BAA and others, including the airlines, but it can be done.

When I went on my last visit abroad and I gave my details to the people from the Office for National Statistics—they wanted to know my details; I do not know whether the Minister had sent someone to the airport to check whether I was coming back or not—I referred to this report by the Public Administration Committee. They were extremely grateful. They knew about it and they said, “When you go back, please remind everybody that we would like to do this survey for everybody, but we’re not given the resources to be able to do that.” I then asked whether it was the quick survey or the long survey and they said, “We’re happy to do the quick survey, but we would like to do everyone rather than the limited number that we do,” so there is a willingness. People want to be helpful. It is not a case of civil servants and other officials wanting to thwart the will of Parliament and the will of the British people; they want to help. Given that and given the arrangements that are made at airports, why on earth can we not bring this change into effect before 7 May 2015?
