Notes:
1. Data tor 1979–90 are based on the international Passenger Survey (IPS) only. Data for 1991–2002 are based mainly on data from the IPS but also include adjustments for (1) those whose intended length of stay changes so that their migrant status changes; (2) asylum seekers and their dependants not covered by the IPS; and (3) flows between the UK and the Republic of Ireland. This means that figures for years from 1991 onwards include all categories of migrants and therefore represent total international migration, while figures for years Drier to 1991 exclude certain categories
2. The estimates for years from 1991 onwards are compiled using the following main sources of migration data in addition to the IPS: Home Office data on asylum seekers and their dependants, and people who entered the UK as short-term visitors but were subsequently granted an extension of stay for a year or longer for other reasons, for example, as students or on the basis of marriage; and estimates of migration between the UK and the Irish Republic.
