1 It is not possible to separately identify and split net migration and other changes in the years up to 2001. For 2002-06 net migration and other changes are shown separately. 2 Other changes primarily include changes in the number of armed forces and dependants resident in the area and also (for years up to and including 2001) a factor to ensure that population change over the intercensal period agrees with estimates derived from the Census.
