§ Mr. Cousins
To ask the Chancellor of the Exchequer what was the annual population(a) inflow to and (b) outflow from the Government Office, North East Region; and what was migration between the Government Office North East Region and (i) other parts of the UK and (ii) other countries in each year from 1992 to 1998. 
§ Miss Melanie Johnson
The information requested falls within the responsibility of the Director of the Office for National Statistics. I have asked him to reply.
Letter from Tim Bolt to Mr. Jim Cousins, dated 20 December 1999:As Director of the Office for National Statistics (ONS), I have been asked to reply to your recent parliamentary question about the estimated in and outflows from and to the North East region.The attached table presents the information you require. The estimates of internal population movements are based on the movement of NHS doctors' patients between the former Family Health Services Authority Areas. They should not be regarded as a perfect measure of migration as there is variation in the delay between a person moving and registering with a new doctor. Additionally, some moves may not result in a re-registration: for example, individuals may migrate again before registering with a doctor. Conversely, there may be others who move and re-register several times a year.Moves between the individual Government Office Regions (GORs) of England and the rest of the United Kingdom are now published in Key Population and Vital Statistics, which is available in the House of Commons Library. Prior to 1997, the analysis related to moves within England and Wales only.The estimates of international (external) migration are derived from the International Passenger Survey (IPS), a sample survey of passengers arriving at and departing from the main air, sea and Channel Tunnel routes. Estimates derived from the IPS are subject to both sampling and non-sampling error. Some types of migrants are not covered by the IPS as it does not cover routes between the UK and the Irish Republic, the Channel Islands and the Isle of Man. All movements of diplomats and armed forces personnel are also excluded, as are asylum seekers and visitor switchers—persons admitted as short-term visitors who are subsequently granted a stay for a year or longer. These estimates can be found in the publication International Migration, which is available in the House of Commons Library.The following table shows total inflow and outflow (in thousands) to and from the North East Government Office Region: to and from the rest of the UK, and to and from outside the UK.431W
