1. Latest news

Even with two periods of Purdah in this quarter we have been very busy with a number of outputs and publications.

What has happened this quarter in population statistics?

The 2014-based Sub-National Population Projections were published showing that all but 9 local authorities (LA) in England are projected to grow in size over the next ten years. In addition to this the population aged 65 and over is projected to grow at the fastest rate compared to other age groups in every region of England. New interactive maps have been used to show how the components of change affect the projected growth of each LA, whilst our interactive population pyramids show how areas are projected to age. If you would like to embed any of these interactive within your content please get in touch at projections@ons.gsi.gov.uk.

We recently published a 2014-based national population projections "Table of Contents” spreadsheet which provides links to all the published data and relevant supporting information to assist customers in finding the 2014-based NPP data they require. The spreadsheet is the first dataset available under national projections. If you have any feedback on whether this is helpful or what might improve it for future use please contact projections@ons.gsi.gov.uk.

This quarter saw the release of the mid-year population estimates, this annual report gives the population size of the UK and its constituent countries. Over the year to mid-2015 the number of people resident in the UK increased by 513,000 (up 0.8%). The population increase of the UK in the year to mid-2015 included natural growth (more births than deaths) of 171,800 people, net international migration of 335,600 and an increase of 5,800 people in the armed forces and prison populations.

On the same day the Internal migration estimates were made available and showed that there were an estimated 2.85 million residents moving between local authorities in England and Wales between July 2014 and June 2015, this is the same level shown the previous year. For those aged in their late 70s onwards, the proportion of people moving slightly rises. There are many reasons why people of this age may wish to move, including being closer to their family, downsizing, or specifically to access support and care.

The most recent release of migration data provided recent estimates on both long-term and short-term migration. These showed that net long-term international migration for the year ending December 2015 was 333,000, but both immigration and emigration saw a slight fall over this period.

The annual short-term international migration estimates, providing information on those arriving to the UK for less than one year, showed that 1.2 million people arrived in England and Wales for 1 to 12 months in the year ending June 2014. This compares to 2.4 million people emigrating over the same period. Nearly 3 out of 4 (73%) of 1 to 12 month short-term immigrants leave within 3 months and all leave within 12 months and the most common reason for both immigration and emigration of short-term migrants was for “other” reasons, which includes visiting family and holidays.

A number of short articles were also produced to help inform the public and to assist people’s understanding of current issues by providing an unbiased overview of our data. These covered a wide range of topics from across the office and included additional articles that had a specific EU focus in light of the EU referendum.

Migration: what is the debate?

Our migration figures have received a lot of attention in the media in the run-up to the European Referendum, particularly around the use of different sources and why they produce different figures. A note on the difference between National Insurance number registrations and the estimate of long-term international migration 2016 has been released, explaining that:

  • Short-term migration to the UK largely accounts for the recent differences between the number of long-term migrants (as estimated by the International Passenger Survey (IPS)) and the number of National Insurance number (NINo) registrations for EU citizens.

  • IPS continues to be the best source of information for measuring long-term international migration (LTIM).

  • NINo registrations data are not a good measure of LTIM, but they do provide a valuable source of information to highlight emerging changes in patterns of migration.

  • Definitional differences between these data are fundamental and it is not possible to provide an accounting type reconciliation that simply ‘adds’ and ‘subtracts’ different elements of the NINo registrations to match the LTIM definitions.

Over the next two years, more analysis will take place to better understand what administrative sources tell us about migration patterns, particularly migrants who may enter and leave the UK several times within a year. This work should help to better understand the measurement of international migration into and out of the UK.

What do you think of our new-look bulletin?

Work has been going on across the office to improve our statistical bulletins, to make them more effective and user-friendly. The first of the bulletins to take on the new approach was the Marriages in England and Wales: 2013 release. Have a look and see what you think, and send any feedback that you have to vsob@ons.gsi.gov.uk.

What will be happening in the next quarter?

This summer we have the annual publication of the population estimates by marital status and living arrangements, Population by country of birth and nationality, National Life Tables and population estimates of the very old. The local area migration indication suite will also be updated.
