1) Exact number of Poles (by country of birth: Poland) in the UK, 2004-2014.
2) Exact number of Poles (by country of birth: Poland) in London, 2004-2014.
3) Exact number of Poles (by country of birth: Poland) in Birmingham, 2004-2014.
4) Exact number of Poles (by country of birth: Poland) in Birmingham for each borough, in 2014 (or 2015).

We said

Thank you for your query about Polish born people living in the UK.

ONS collects data on the country of birth and nationality of the UK population from the Annual Population Survey (APS). The APS is the Labour Force Survey (LFS) plus various sample boosts. It is a household survey and so does not include people living in most types of communal establishment. Please note that calendar year 2014 is the latest data available. Data for 2015 will be published 25 August.

The figures you have requested for questions 1, 2 and 3 can be found on the ONS website, but unfortunately the ONS does not publish any estimates of migrant stocks below local authority level, and so we are unable to assist you with question 4.

Please note: Estimates within the tables are provided alongside 95% confidence intervals to indicate the reliability of the estimate. These confidence intervals provide a range (by adding to, and subtracting from, the estimate) in which the true value is likely to lie. There is a 95% probability that the true figure lies within this range. Users should be cautious when making inferences from estimates with large confidence intervals. If the confidence interval is higher than the estimate, it is not considered reliable for practical purposes.

Further information on the APS is available in the "Notes to tables" section located within the spreadsheets.

I hope this answers your questions but please let me know if you need any further information.
