This dataset provides 2001 Census estimates that classify usual residents in England and Wales in area and those having moved from the area to within the the UK in the past year by resident type and age by migration (OA/Ward Only). The estimates are as at census day, 29 April 2001.

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.

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.

People with no usual address one year ago are included within 'lived at same address, or moved from within same area'.

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

In 'Migration': 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.

Figures have been randomly adjusted to avoid the release of confidential data
