Letter for publication in response to an article on the Guardian website, 16 July 2012

Issue date: 18 July 2012
Type: Letter to the Press

Dear Sir,

You assert that the International Passenger Survey (IPS) is 'notoriously unreliable', 'too small' and 'does not sample randomly' (Census 2011: population rise due to dodgy data, Guardian website 16 July). This is incorrect: the IPS does indeed use a random sample, and surveys over 800,000 travellers a year. It has been subject to a thorough review as part of the cross-government Migration Statistics Improvement Programme and this has been seen as very successful by stakeholders and users.

Yours faithfully,

Ben Humberstone
Deputy Director, Head of Population Statistics
