Welcome to the autumn 2021 edition of the migration and population statistics newsletter.  In this edition news on recent and upcoming releases and events, together with updates on the work we have been doing in the last quarter.

Look out for the next edition in the winter.

Travel and tourism consultation - 5 October 2021 

On the 5 October a public user consultation will be opened to gather feedback on the approach proposed to transform travel and tourism statistics. Alongside this, an article on the progress made throughout the review along with a methodology paper will be published on the ONS website. 

Census 2021 outputs consultation - 5 October 2021

The census outputs and analysis consultation is running to the 5 October. If you haven’t done so already, please consider responding and let us know how we should deliver our outputs.

The consultation will remain open until midnight on 5 October 2021.  We recommend you respond to the consultation in our online questionnaire.

You can also download a Microsoft Word version of the questionnaire from the consultation webpage and email your response to census.outputs@ons.gov.uk

Migration Statistics User Forum - 14 October 2021

We are hosting the Migration Statistics User Forum (MSUF) as a virtual event on 14 October 2021. This is a day event which will be entirely online in order to reach a wide range of users and provide a platform for discussion on international migration statistics. There will be three sessions throughout the day covering recent developments affecting migration statistics, big data and migration, and local area challenges and data potential. The event is free to attend and can be booked via Eventbrite – a link will be sent closer to the time.

International migration - autumn 2021 

We will publish modelled estimates of international migration flows for June to December 2020 in autumn 2021. This builds on the method used in April 2021 to estimate flows for the first few months of the coronavirus pandemic.  We will also be publishing our next update of “Population of the UK by country of birth and nationality”, covering data up to June 2021.

Research on population and migration estimates and projections  

In July we published our future plans for research on population estimates and projections, which contains an outline of our work plan to address the recommendations in the Office for Statistics Regulation (OSR) review of ONS population estimates and projections. Since then we have:

  • begun work on producing and analysing measures of uncertainty at the local level for the mid-2020 population estimates, which are scheduled for publication on 26 November
  • been exploring the quality indicators we use in the production and reporting of the population estimates and projections
  • begun producing a draft framework to enable users of population statistics to provide us with local insight into population change and uncertainty
  • explored some case studies into the use of variant population projections.

In the autumn we will be publishing our progress of research on our Administrative based population and migration estimates (ABMEs and ABPEs). We will provide a fuller update in publications during November and will keep you updated as dates for these become finalised.

Virtual Third Technical Meeting of the Titchfield City Group on Ageing (TCGA)


The third technical meeting for the TCGA took place virtually over three days from 29 June to the 1 July. Almost 200 delegates registered including representatives from 24 National Statistical Offices (NSOs), UN groups such as UN Women and the UN Development Programme, the World Health Organisation, Help Age International and academic experts. Both current members and newly interested participants engaged. 

During the three days, work strand leads and delegates discussed progress on the three priority TCGA work strands and launched two data collection exercises. The first exercise to conduct analysis on the data gaps for SDG (Strategic Development Goals) indicators on ageing and older persons. The second exercise to collect data from NSOs on one selected indicator to help develop the conceptual and analytical framework for information on older persons.

A full report of the third technical meeting is available via the TCGA wiki page. Please email TCGA@ons.gov.uk for more information.

Measuring migration: the story behind the headlines 

On 17 September, the Centre for International Migration published a new interactive article focused on Measuring migration: the story behind the headlines. The migration of people in and out of the UK has been in the news recently, with stories about shortages of lorry drivers, EU citizens leaving the UK, and the crisis in Afghanistan resulting in emergency airlifts of refugees. This short article takes you behind the headlines and uses the latest data to answer questions about international migration. We also explain why measuring migration is harder than you might think.
