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
