§ Mr. Marlow
To ask the Secretary of State for National Heritage, pursuant to his answer of the 14 December 1992,Official Report, column 14, on flights to and from the Indian sub-continent, what assessment he has made of the reasons for (a) the difference between the number of arrivals and departures in each year and (b) the trend in the difference.
§ Mr. Key
Reliable conclusions cannot necessarily be drawn from the differences between the data on passengers arriving and departing on flights from or to the Indian sub-continent. This is because the data relate to all such passengers irrespective of where they joined or left the flights, and also because the data include passengers who changed flights in the United Kingdom without passing through immigration control.
Information up to 1990 on international migration to and from the Indian sub-continent is given in the Office of Population Censuses and Surveys' annual reference volume "International Migration 1990". Information up to 1991 on citizens of Indian sub-continent countries who were accepted for settlement, that is, allowed to stay indefinitely in the United Kingdom, is given in the Home Office Command Paper "Control of Immigration: Statistics, United Kingdom, 1991". Both of these publications are available in the Library of the House.
