Immigration Statistics Anxiety: how 800,000 becomes 1,100,000

Am I the only one who’s befuddled by this immigration debate?

It seems that 800,000 should have been 1,100,000 and the Labour Force Survey is implicated.

Where should I look to find out more?

(Is it a case of errors in a residual? This is so often the curse of apparently very large and whimsical errors, but may not be the culprit in this case.)

In my naïve way, I can’t see why the aggregate figures can’t just be obtained by checking people as they come in and go out. (We are all checked, after all!)

The important things seem to be age/sex/birthplace/nationality, and maybe what the hell are you doing here and where are you going? (as it’s the local figures which are really important for policy terms)

Should the Radical Stats ImmigrationWatch Watch team be issuing a press release which I and the average Daily Mail reader can understand?

My main worry is that Immigration Anxiety and every other sort of Anxiety is rapidly becoming a Statistics Anxiety.
