Dear Lord Green,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your

Parliamentary Question asking, further to the Written Answer by Baroness Anderson of

Stoke-on-Trent on 7 July (HL1157) [1], how many households in (1) Greater London, and (2)

the United Kingdom, had a household reference person born (a) in the United Kingdom,

and (b) outside the United Kingdom, in the 2001 Census (HL1903).

The census is conducted separately by the statistical agencies for England and Wales,

Scotland, and Northern Ireland, and outputs are published independently. There is no

single UK-wide 2001 Census dataset. Therefore, the data presented here relates to Greater

London and England and Wales rather than the UK.

Table 1 below shows the number of households with a Household Reference Person (HRP)

born in and outside of the UK for Greater London and for England and Wales. The figures

for Greater London include all 32 boroughs and the City of London.

Please note that these figures are not available as part of the 2001 Census standard

outputs and were produced through our commissioned tables service. Table C1341 shows

the data at the England and Wales level, and C1347 shows the data at the London

Borough level.

We will place copies of these commissioned tables in the House of Lords Library.

Yours sincerely,

Darren Tierney

Dear Lady Finn,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking, further to the Written Answer by Baroness Anderson of Stoke-on-Trent on 23 June (HL740)[1], what occupational socio-economic classification the Office for National Statistics and the Social Mobility Commission applies to (1) Ministers of the Crown, and (2) the Prime Minister (HL1331).

The ONS classifies Ministers of the Crown and the Prime Minister to the Standard Occupational Classification (SOC) 2020 code 1112, which corresponds to ‘Elected officers and representatives’. Under the simplified National Statistics Socio-economic classification (NS-SEC) framework, this occupation is classified as analytic class 1: Higher managerial, administrative, and professional occupations.

There are 8 analytic classes in the NS-SEC used by the ONS. The Social Mobility Commission group these into 5 categories, as per Table 1 in the supporting Annex below.

Yours sincerely,

Darren Tierney

Dear Lord Wigley,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking what is the latest estimate of population growth over the most recent five year period in (1) England, (2) Wales, (3) Scotland and (4) Northern Ireland (HL1519).

The most recent available population estimates(1) for England, Wales, Scotland and Northern Ireland for the five-year period between mid-2019 and mid-2024 can be found in table 1 below.

Population estimates are regularly revised to incorporate new data and methods and should not be taken to be accurate to the level of precision provided.

On 29 July 2026, we will be publishing population estimates for England and Wales for mid- 2025. On 14 July 2026 the National Records for Scotland will be publishing population estimates for Scotland for mid-2025. In September/October 2026, the Northern Ireland Statistics and Research Agency will publish population estimates for Northern Ireland for mid-2025.

Dear Lord Green,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking how many households in (1) Greater London, and (2) the United Kingdom, had a household reference person born (a) in the United Kingdom, and (b) outside the United Kingdom, in 2010 and 2025 (HL1157).

The information is derived from census data and is therefore available for 2011 and 2021.

However, there is no single UK-wide census dataset. The census is conducted separately by the statistical agencies for England and Wales, Scotland, and Northern Ireland, and outputs are published independently.

As a result, the data presented here relates to England and Wales only (with London shown separately), rather than the UK as a whole.

Table 1 below shows the number of households with a Household Reference Person (HRP) born in and outside of the UK for London and for England and Wales. The figures for London include all 32 boroughs and the City of London. For the 2011 Census, the data was not available as part of the standard outputs. As a result, it was produced separately through our commissioned tables service. The 2011 dataset is from 2011 Census commissioned table CT0237.

The 2021 Census data in table 1 below was obtained using the ONS’s ‘Create a custom dataset’ tool. We will place a copy of this dataset, HL1157 2021 Census custom dataset, HRP England and Wales & London, in the House of Commons Library.

Yours sincerely,

Darren Tierney

Dear Baroness Smith,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking what the median gross weekly pay for adults in full-time work in each region of the UK is (HL529).

The Annual Survey of Hours and Earnings (ASHE), carried out in April each year, is the most comprehensive source of earnings information in the United Kingdom. ASHE is based on a 1% sample of employee jobs taken from HM Revenue and Customs' Pay as You Earn (PAYE) records.

Table 1 below shows the median gross weekly pay for full-time employee jobs on adult rates by region for April 2025[1], taken from the Annual Survey of Hours and Earnings (ASHE). April 2025 is the latest period for which ASHE estimates are available. As with any survey, estimates from ASHE are subject to a margin of uncertainty.

The April 2025 data is provisional and will be revised in line with normal practice for our October 2026 publication.

The information provided can be found in our latest publication Employee earnings in the UK: 2025[2] and in ASHE Table 3[3].

More timely data on average weekly earnings is published in our Average weekly earnings (AWE) in Great Britain publication[4]. Our AWE average weekly earnings are our short-term measure of employee earnings and provide an estimate of mean pay for full-time and part- time employees combined. While AWE does not provide median weekly pay for full-time employees and are not available at region level, the most recent data (first quarter of 2026), give an indication of how employee pay has grown in the last year. Our latest estimates from AWE indicate that annual growth in average regular earnings (excluding bonuses) in Great Britain was 3.4% in the three-month period to March 2026.

Dear Lord Wigley,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking how many immigrants took residence in the UK in the latest year for which figures are available; and how many of those came to the UK by small boat crossing of the English Channel (HL15948).

Based on our latest estimates[1] which look at long-term international migration (long-term is where people change their usual place of residence for a period of 12 months or more). In the year ending June 2025, we estimated that:

• 898,000 people came to the UK for 12 months or more

• 693,000 people left the UK for 12 months or more

• Therefore, net migration was estimated at 204,000[2]

While these figures include those arriving for asylum, the ONS does not produce estimates on the number of arrivals by small boat. However, the Home Office and Border Force provide data on small boat arrivals for the last 7 days[3] and a timeseries updated weekly back to 2018. In year ending June 2025, the Home Office estimates that the number of people recorded as arriving in the UK on small boats was 43,309[4].

Those arriving in small boats who claim asylum would appear in our asylum estimates. In year ending June 2025, the ONS immigration estimate includes a total of 96,000 people that came to the UK for asylum.

Yours sincerely,

Darren Tierney

Dear Lord Clement-Jones,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Questions, asking whether the UK submitted any nominations for the UN Consultative Advisory Board on the Fundamental Principles of Official Statistics, and what steps they are taking to ensure UK expertise contributes to the Board's global mandate(HL16600); what, if any, financial or human resources they plan to contribute to the UN Statistics Division to support the operations of the UN's Consultative Advisory Board on the Fundamental Principles of Official Statistics (HL16601); whether the UK Statistics Authority will outline the national mechanisms in place in the UK to resolve issues regarding adherence to the UN's Fundamental Principles of Official Statistics, in light of the UN Consultative Advisory Board on the Fundamental Principles of Official Statistics' principle of subsidiarity (HL16602); how the UK Statistics Authority plans to engage with the UN's Consultative Advisory Board on the Fundamental Principles of Official Statistics to ensure that UK statistical producers adopt the Board's forthcoming updated implementation guidelines (HL16603) and how the UK Statistics Authority plan to assist the UN's Consultative Advisory Board on the Fundamental Principles of Official Statistics in its mandate to raise global awareness and facilitate dialogue sessions with policymakers to build trust in official statistics (HL16604)

The UK was involved in the development of the Consultative Advisory Board and its terms of reference, alongside like-minded partners, to ensure it is relevant and impactful for those who request its support. The ONS was not asked to be a member of the board, and its membership was nominated by the Bureau of the UN Statistical Commission. It is worth noting that membership rotates and the UK will have the opportunity to join in the future.

The UK continues to support the work of the UN Statistical Division, as it is one of the most prominent organisations working in global statistics. We are a member of the wider UN Statistical Commission’s membership and have been since its creation1. We continue to provide resource through our engagement and chairing of UN working groups and bureaus, leading the delivery of projects relevant to the production and dissemination of statistics.

The Code of Practice for Statistics2 sets standards that producers of official statistics should commit to and is already consistent with the UN Fundamental Principles. This is maintained by the Office for Statistics Regulation, the regulatory arm of the UK Statistics Authority.

The ONS will engage with the work of the Consultative Advisory Board through the usual member state engagement conducted for updates to manuals and guidelines produced by the UN Statistical Commission, the UN Statistical Division, or its regional commissions. This process is outlined with the terms of reference3 for the board.

Finally, the ONS regularly assists in efforts to highlight the importance of the Fundamental Principles of Official Statistics, taking part in events to increase their profile, including its 30th anniversary events in 20244. In addition to this, as mentioned above, we will oversee the work of the Advisory Board, engaging directly with its annual reports, and we will play an active role in the review of the Board’s work that is expected to be completed after its first year. This will help to ensure the work is impactful and relevant for statistical producers, whose outputs policy makers rely upon.

Yours sincerely,

Darren Tierney

In December 2025, in the UK, there were an estimated 10,000 workforce jobs1 in the mining of coal and lignite; extraction of crude petrol/gas sector (standard industrial classification (SIC) divisions 05-06), a decrease of 2,000 compared with December 2024.

In December 2025, in the UK, there were an estimated 8,000 workforce jobs1 in the manufacture of coke and refined petroleum products sector (standard industrial classification (SIC) division 19), a decrease of 2,000 compared with December 2024.

In December 2025, in the UK, there were 99,000 workforce jobs2 in the manufacture of chemicals and chemical products sector (standard industrial classification (SIC) division 20), an increase of 2,000 compared with December 2024.

A full time series of data can be found in Table 1. Please note that these data are not

seasonally adjusted.

Dear Lord Redwood,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking how many industrial plants employing over 200 people have closed in the last year (HL15771).

It is not possible to answer the question as asked because these data are not available by the number of employees. However, by using the quarterly business demography dataset[1], it is possible to make an estimate of the number of businesses within the production industries which have closed in the last year.

The number of businesses within the production industries which have closed in the year 2025 is estimated to be 12,510.

The quarterly business demography statistical release is regarded as ‘official statistics in development’.

Yours sincerely,

Darren Tierney

Dear Baroness Whitaker,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking what steps are being taken to improve the accuracy, consistency, and disaggregation of ethnicity data relating to Gypsy, Roma and Traveller communities across public services, following research set out in the Advicenow briefing Unpacking imperfect data: Roma overrepresentation and the need for analytical precision, published in November 2025, indicating that current data practices prevent a reliable understanding of levels of need and representation of Gypsy, Roma and Traveller children in care (HL15068).

The Government Statistical Service’s (GSS) harmonisation team oversees the development and review of harmonised standards [1] for statistical data collection across the public sector. In developing harmonised standards, the GSS harmonisation team considers the data needed to inform policy, for equalities monitoring and for service delivery. This enhances the value from public sector data collections by improving the comparability and coherence of statistics across sources. We acknowledge the difficulty in data collection and disaggregation for some populations, particularly where sample sizes are small.

The current ethnicity harmonised standard [2] is based on the 2011 Census questions across the UK. The questions were reviewed and adjusted so they could be used in the 2021 Census for England and Wales, the 2021 Census for Northern Ireland, and the 2022 Census for Scotland. In these censuses, the category “Gypsy or Irish Traveller” was included as a tick box in England, Wales, and Scotland. In Northern Ireland, this category was tailored specifically to “Irish Traveller”. As part of the 2021 census updates, “Roma” was included as a separate tick box option in all nations.

The GSS is currently reviewing the harmonised standard on ethnicity, with the intention to encourage consistent and inclusive data collection across the Government Statistical Service. As part of the review, the team recently ran a public consultation [3] to gather evidence of user, community, and respondent need for additional tick boxes in the new ethnicity harmonised standard; ethnic groups represented in existing response options, as described above, will be retained.

The proposed new ethnicity harmonised standard for online data collection will be published by the end of 2026. We have published wider detail on the programme of work online [4]. We are working closely with departments and organisations across government to encourage adoption of the harmonised standard and support its effective implementation.

While we encourage data collectors in the GSS to align to harmonised standards, they are not compelled to do so. Some non-statistical data collectors in the public sector and beyond also align, though due to operational constraints sometimes this alignment is not always to the latest standard. Meanwhile, the GSS recognises that some data collectors choose not to align because their needs for data differ. This is why the options for responding to ethnicity questions vary across different data collectors.

Additionally, a team within the UK Statistics Authority is conducting qualitative research with Roma communities in England and Wales, due to be published later this year. The findings will support a more nuanced understanding of their lived experience and specific needs, as well as providing insights to inform statistical producers in considering how Roma identity is represented and captured in data in the future.

Yours sincerely,

Darren Tierney

Dear Lord Freyberg,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking a) further to the Written Answer by Lord Livermore on 17 February (HL14181), whether the Office for National Statistics has assessed the feasibility and statistical acceptability of aggregating multiple Standard Occupational Classification codes that individually fall below publication thresholds into higher-level sector groupings for publication purposes; and if so, what conclusions were reached (HL14677); and b) what statistical disclosure control techniques, including aggregation, rounding, banding or noise adjustment, are available to the Office for National Statistics to enable publication of sectorlevel occupational data derived from low-count Standard Occupational Classification categories (HL14679).

The Standard Occupational Classification (SOC) codes are routinely used for statistical outputs. SOC codes are designed with a hierarchical structure, ranging from 1-digit codes for the broadest categories, 2 = ‘Professional occupations’ for example, to 4-digit codes for the most detailed categories, 2451 = ‘Architects’ for example. The SOC ‘nested’ structure means multiple Standard Occupation Classification codes are aggregated into higher-level groupings by design. The use of these standard groupings allows for better comparisons over time and with other data sources. Statistical outputs that the ONS produces will use an appropriate level of detail of SOC codes, aiming to balance the need for detailed occupation information, with the possibility of smaller categories falling below the publication threshold. Further information about the SOC classification can be found on the ONS website. There is currently a consultation to update SOC2020 because of the continual evolution of occupations, and to ensure that SOC reflects significant changes in the labour market. Submissions to the consultation are live until 11 May 2026.

All the disclosure control techniques you reference in your question are available to use. Aggregation and banding are the most used methods to increase the number of contributors. The choice of disclosure method depends on the source of data, user needs, disclosure risk and other related factors. The disclosure control methods applied are always designed to maximise the usefulness of the data whilst protecting the confidentiality of the contributors.

Yours sincerely,

Darren Tierney

Dear Lord Mott,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking what assessment has been made of the number of UK hospitality businesses that have ceased trading since November 2024 (HL14742).

Information on the number of businesses which have ceased trading is best obtained from the ONS’s annual business demography release, which has the Inter-Departmental Business Register as its data source. However, the latest year for which figures are available from this data source is 2024.

The ONS publishes more up-to-date estimates of business closures via our quarterly business demography release. The figures in this release are regarded as ‘official statistics in development’. It is not possible to separately identify the hospitality industry in the quarterly data, but figures are available for accommodation and food as a whole. Table 1 shows the number of business closures in the United Kingdom (UK), from the fourth quarter of 2024 to the fourth quarter of 2025.

Dear Lord Freyberg

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking whether the Transformed Labour Force Survey (TLFS) records secondary occupations or ongoing professional identities when someone has more than one type of work; and what assessment they have made of how recording only a person’s main job may affect sectors where many people have portfolio careers, such as crafts and the visual arts (HL14678).

The TLFS does collect information on a respondent’s secondary occupation. Where the respondent has a portfolio career such as those mentioned, they can self-determine this as their main or second job. The data collected includes for example, whether this is in an employed or self-employed capacity, the hours usually and actually worked, the pay received and the industry and occupation code of the position. This data is used for a variety of statistical, legislative and policy purposes by a broad range of stakeholders.

Information is collected for up to two jobs. There has previously been a question as to whether information on more than two jobs should be collected. However, there must be a careful balance achieved between data users need, and the respondent burden caused by survey length. While we are not currently in a position to capture more than two jobs, this issue will be thoroughly explored within future developments of the TLFS.

The TLFS also collects data on casual working roles so that those in more informal situations are also captured.

Yours sincerely,

Darren Tierney

Dear Lord Freyberg,

As Permanent Secretary of the Office for National Statistics (ONS), I am responding to your Parliamentary Question asking whether there is a plan to incorporate self-assessment income tax data into the Inter-Departmental Business Register; if so, when to expect that data to be incorporated; and what assessment has been made of the impact of including that data on the representation of sole traders and businesses operating below the VAT threshold in official economic statistics (HL14179).

The ONS is currently developing a new Statistical Business Register (SBR), which will replace the Inter-Departmental Business Register. We are planning to incorporate self-assessment income tax into the new SBR and are working closely with HM Revenue and Customs with the current expectation that they will be able to share the data later this year. We will then assess the data with a plan to incorporate into the SBR and assess the impact of the self-assessment data on economic statistics of businesses operating below the VAT threshold.

Yours sincerely,

Darren Tierney
