§ Mr. WigleyTo ask the Secretary of State for Wales if he will make it his policy to publish data showing(a) the volume of in-migration into Welsh counties and districts and (b) the age structure of the inward-migrating population; and if he has any plans to conduct a survey to ascertain the reasons for inward-migration into Wales and its effect on the indigenous population.
§ Mr. Nicholas BennettData on in and out migration, based on the re-registration of NHS general practitioners' patients and by broad age groups, are published at a county level by the Office of Population Censuses and Surveys in table 5.1 of "Key Population and Vital Statistics" annual series VS/PP1. The OPCS also produces estimates of net migration for counties and county districts and publish these in table 4 of the OPCS monitor series PP1. Both are available in the Library of the House.
Information on the scale, origin, destination and characteristics of migration flows for the year prior to the 1991 census will become available over the next year when the full processing of the census returns has been completed.
