Notes and Definitions
The estimated population of an area includes all those usually resident there whatever their nationality. Students are treated as being resident at their term-time address. Members of HM and non-UK armed forces stationed in Scotland are included; HM forces stationed outside Scotland are excluded.
Population figures relate to 30 June of the year shown and ages relate to age last birthday.
Presentation of results
Although the populations are tabulated in units, this does not imply accuracy to that level. The data are presented in units for the convenience of users wishing to compile non-standard aggregations without encountering rounding problems.

1. Use of Community Health Index (CHI)
As in 2002, the 2003 mid-year estimates used the Community Health Index for estimating migration at council area. An overview of how the CHI is used can be found here.
2. Unattributable Population Change
In addition to the new method and data source for estimating migration, a further adjustment was made to the migration estimates. The estimated civilian migration component includes an adjustment for recurring unattributable population change. This is assumed to be unmeasured migration. The adjustment is based on the 2001 Census, which showed that previous population estimates had overestimated the population of Scotland by some 50,000. This overestimate is largely due to errors in previous migration estimates in the 1980s and 1990s. To ensure that migration estimates do not continue to be overestimated an adjustment has been included in the 2003 mid-year estimates.
This adjustment is included within the net civilian migration column in Table 1 as it is assumed to be wholly comprised of unmeasured migration. At Scotland level, this amounts to -2,600 and is the same as that used in the 2002 mid-year estimates.
Further work is being undertaken to review the quality of the method and data sources used to estimate migration.
