Letter from Len Cook to Mr. John Hemming, dated
As National Statistician, I have been asked to reply to your recent Parliamentary Question regarding the number of people emigrating from the United Kingdom in each year since 1990. (904)
Estimates of emigration from the UK are shown in the attached table. The figures are based on the most comprehensive estimate of migration produced by the Office for National Statistics, "Total International Migration" (TIM), which is based on a number of sources. TIM estimates using the current methodology are only available from 1991 onwards and the latest estimates, for 2003, were published in the annual reference volume International Migration, Series MN no. 30, on the National Statistics website at the link below on 28th April 2005: http://www.statistics.gov.uk/STATBASE/Product.asp?vlnk=507
|Outflow (emigration out of the UK)—All citizenships|
(6) Data for 1991–2002 are based mainly on data from the International Passenger Survey. Includes adjustments for (1) those whose intended length of stay changes so that their migrant status changes; (2) asylum seekers and their dependants not identified by the IPS; and (3) flows between the UK and the Republic of Ireland.
A small weighting adjustment has been applied to IPS data for 1991 to 1998. This reflects the estimated effect of applying the weighting improvements made to IPS data from 1999 onwards.
