This dataset provides 2001 Census estimates that classify people in area and those having moved from the area to within the UK in the past year by resident type and sex and age by migration. The estimates are as at census day, 29 April 2001.

Net migration within the UK (Inflow minus Outflow) subtracts the number of people who have moved out of the area, to elsewhere within the UK (Outflow) from the number of people who have moved into the area, from elsewhere within the UK (Inflow). It does not include people who have moved to or from outside the UK.

The term 'area' refers to the particular area level being shown in the table. So, in the case of a table for a ward, this will mean the term 'area' translates to the name of the ward.

Inflow is not an exact count of people moving into an area as it does not include people who had no usual address one year ago who did not live within the area.

Outflow is not a count of all people moving out of the area as it does not include people who have moved outside the UK.

One year ago is one year before Census day (29 April 2001).

In England and Wales 'associated area' refers to Local Authority District for tables at Ward(Electoral Division in Wales); Parish (Community in Wales) or Output Area level. For all other geographical areas the 'associated area' is England and Wales.

This dataset provides 2001 Census estimates that classify households in the area and those having moved from area in the past year within the UK by age of Household Reference Person (HRP) and number of dependent children by migration of households. The estimates are as at census day, 29 April 2001.

A dependent child is a person in a household aged 0 to 15 (whether or not in a family) or a person aged 16 to 18 who is a full-time student in a family with parent(s). An adult in a household is defined as a person who is not a dependent child.

A wholly moving household is one where all members of the household have moved from the same address.

Partly moving households' include households where no household member had a usual address one year ago.

Persons under one year old take the migration characteristics of their next of kin, i.e. a household containing a child under one year old where all other people in the household have not moved in the last year is recorded as 'whole household lived at the same address one year ago' rather than a partly moving household.
