HC Deb 19 January 1970 vol 794 cc35-6W
Mr. Nott

asked the Secretary of State for Social Services what statistics are kept in his Department to show the trend of population movement in the period between 1960 to 1969 in Cornwall, the area covered by the St. Ives Parliamentary Division and the Falmouth-Camborne Division.

Dr. John Dunwoody

The General Register Office keeps records of births, deaths and the number of Parliamentary electors in each local authority area. These, together with information from the latest Census of Population and data derived from an annual return of housing development, etc., are used in compiling estimates of local populations at each mid-year. The estimated change in population can be analysed to give a net migration component in addition to natural change.

Information about migration was collected in the 1961 Census and the 1966 Sample Census of population but is not published for Parliamentary constituency areas, only for Local Authority areas.

Over the period 1966 to 1969 the trend of population movement in each of the two Parliamentary Divisions mentioned has been one of increase. The Registrar General estimates that, compared with a national increase of 7 per cent., the increase in the area covered by the St. Ives Parliamentary Division was 4 per cent. and in the area covered by the Falmouth-Camborne Division 8 per cent. But whereas only 15 per cent. of the national increase was due to net civilian migration, 81 per cent. of the population increase in the Falmouth-Camborne Parliamentary Division and over 90 per cent. of that in the St. Ives Parliamentary Division were due to net civilian migration.
