POPULATION BY NATIONALITY
Slough

The population figure shown for your area are an estimate provided by the Office for National Statistics and is rounded to the nearest 1,000.

The estimates are derived from the Annual Population Survey (APS) which is the Labour Force Survey (LFS) plus various sample boosts.

The Labour Force Survey (LFS) is a household survey of people in the UK. It includes those deemed resident at private addresses, so covers students in halls of residence with parents resident in the UK. However, it does not cover most communal establishments. Its purpose is to provide information on the UK labour market but it includes data on a variety of other variables such as country of birth and nationality.

The Annual Population Survey (APS) combines results from the LFS and the English, Welsh and Scottish Labour Force Survey boosts. These boosts increase the size of the sample. During 2004 and 2005 the APS also comprised of an additional boost for England.

Each quarter’s LFS sample of 40,000 households is made up from five “waves”, each of approximately 8,000 households. Each wave is interviewed in five successive quarters, such that in any one quarter, one wave will be receiving their first interview, one wave their second and so on, with one wave receiving their fifth and final interview. Thus there is an 80 per cent overlap in the samples for each successive quarter and the sample is completely different after six quarters.

In some areas of the UK the boost makes up the bulk of the APS dataset, with a smaller contribution from the main LFS. The boost has a four year wave structure instead of the five quarter wave structure in the main LFS; after the initial interview, sampled households are interviewed three more times on an annual basis. Therefore the boost for these areas may be slower to react to a change in migration patterns than the main LFS and the speed with which the APS sample responds to changes in the household population may vary across the UK.

More robust estimates are available by using the APS than from the main LFS. APS datasets are produced quarterly with each dataset containing 12 months of data. There are approximately 300,000 persons per dataset.
