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 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 Lord Green,
As National Statistician and Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary Questions asking how many arrivals by (1) Ukrainians and their dependants, (2) Hong Kong BNOs and their dependants, and (3) Afghan citizens and their dependants, are included in the latest Office for National Statistics net migration figures, published on 24 November; and when the International Passenger Survey (IPS) stopped being used as a significant element in calculating net migration; and what has taken its place (HL3965;HL3966).
In the Office for National Statistics (ONS) bulletin published on 24 November, Section 4, Migration Events[1] details the following published Home Office data included in the ONS’ total long-term international migration estimates:
Ukrainians: around 89,000 arrived in the UK in the year to June 2022
Afghans: around 21,000 arrived in the UK in the year to June 2022
For British nationals overseas (BN(O)) status holders and their families from Hong Kong, colleagues from the ONS and the Home Office are working together to resolve how we identify those that are long-term international migrants in the data. Home Office statistics show that around 76,000 visas were issued for the BN(O) route in the year ending June 2022. This will represent the upper bound for arrivals, as not all of those with a visa will arrive in the UK or stay long term. The ONS is also working to identify BN(O) status holders in their International Passenger Survey (IPS) data using country of birth and country of last residences as this may help provide a more robust estimate. Current analysis suggests that 28,000 British nationals with a country of birth of Hong Kong immigrated into the UK in the year ending June 2022.
The long-term international migration data from the IPS was the largest component of the LongTerm International Migration (LTIM) estimates until its suspension in March 2020 because of the coronavirus (COVID-19) pandemic.
In August 2020 the ONS announced that they would not return to producing official migration statistics from the IPS because it had been stretched beyond its original purpose. The ONS now focuses on measuring actual migration, as opposed to intentions, using primarily administrative data (admin-based migration estimates (ABMEs)). The ONS’ International migration statistical design progress report: July 2022 provides more information.[2]
For the latest long-term international migration estimates; non-EU figures are based on Home Office Border Systems data, EU figures are based on Registration and Population Interaction Database (RAPID) data received from Department for Work and Pensions and HM Revenue and Customs, and British Nationals figures are based on the International Passenger Survey (IPS). See the Measuring the data section[3] for more detail. Thank you for your continued interest in our international migration estimates.

Question to the Cabinet Office:
To ask Her Majesty's Government, for each year from 2010 to date, how many UK households there were (1) with a non-UK born household reference person, (2) with a UK-born household reference person, and (3) with a household reference person for whom the country of birth was not known.

Dear Lord Green,
As National Statistician and Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary Question requesting data for how many UK households there were (1) with a non-UK born household reference person, (2) with a UK-born household reference person, and (3) with a household reference person for whom the country of birth was not known (HL2843).
The Office for National Statistics is responsible for undertaking the Labour Force Survey (LFS), from which these estimates of household reference person by country of birth have been derived. Table 1 shows the number of households by the household reference person’s country of birth in the UK from 2010 to 20201.
The table contains estimates of the number of households for household reference persons who are UK born, non-UK born or whose country of birth is missing. The totals of each column may not add up to the total households figure due to rounding, and estimates are rounded to the nearest hundred. As the estimates are based on a survey, they are subject to sampling variability. This is because the sample selected is only one of a large number of possible samples that could have been drawn from the population.
Yours sincerely,
Professor Sir Ian Diamond
1. A household reference person (HRP) is the householder who owns the accommodation; is legally responsible for the rent; or occupies the accommodation as reward of their employment, or through some relationship to its owner who is not a member of the household. If there are joint householders, the one with the highest income is the HRP. If their income is the same, then the eldest one is the HRP.

Question to the Cabinet Office:
To ask Her Majesty's Government what is their estimate of the number of workers in the UK who are paid more than £21,000 a year.
Answered by Lord Young of Cookham
The information requested falls within the responsibility of the UK Statistics Authority. I have asked the Authority to reply.
Letter from John Pullinger, National Statistician, to The Lord Green, dated 9 January 2019.
Dear Lord Green,
As National Statistician and Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary Question asking what the estimate of the number of workers in the UK is who are paid more than £21,000 a year (HL12559).
The Annual Survey of Hours and Earnings [1] (ASHE), carried out in April each year is the most comprehensive source of earnings information in the United Kingdom. ASHE is used to produce estimates of the number of employee jobs, which are defined as those held by employees and not the self-employed. Please note that ASHE is based on a 1% sample of employee jobs taken from HM Revenue and Customs' Pay As You Earn (PAYE) records. Consequently, individuals with more than one job may appear in the sample more than once.
The estimate of employee jobs earning more than £21,000 per year in April 2018 [2] (the latest period for which ASHE estimates are available) in the UK is 12,826,000. This estimate includes apprentices and is based upon employees that have been in their current job for at least a year and are on an adult rate of pay. Yours sincerely, John Pullinger
[2] 2018 data are provisional.
