I just worked out that if the figure WB gave, of 1-3 million is anything to go on, we can take an average and say 2 million. In a total population of about 60 587 000, that makes about 3.3%. If we assume that this population is fairly evenly spread across the country, then an average town like St. Albans (population 82 100) should be home to approximately 2700 Polish people.
Why, when I went into a Polish delicatessen there yesterday (on a Saturday afternoon), were there no other customers?
Absurd.The population distribution is not similar everywhere. guess that there are areas with exremely high proportion of Poles and areas with no Poles at all.
My guess:You will never know the exact number of immigrants and absolutely never their distribution.It is not sth of interest for you,it is important for other persons who have interest in these numbers.
How would I estimate the number roughly.How much was the unemployment in Poland before 2004?21%.How much is it now?11%.This means that almost 10% of the working population has migrated.I suppose that 90% at least have migrated to UK.You get the number of all population of working age in Poland,divide by 9 and multiply by 90%.So you get roughly the number of polish immigrants in UK.
