Children looked after return: guide to submitting data

How local authorities should collect and submit data for the annual children looked after return (also known as SSDA903).

The children looked after return is an annual statutory data collection for all local authorities. You must complete statutory censuses by law unless there’s a good reason not to.

The data covers the financial year (1 April to 31 March). It records details of:

  • every child your local authority looks after at any time during the year
  • all young people who are eligible for care leaver support and whose 17th, 18th, 19th, 20th or 21st birthday falls within the collection period
  • information on the health of children who have been looked after continuously for 12 months
  • information on adoptions of looked-after children

Under the Children Act 1989, a child is legally defined as ‘looked after’ by a local authority if he or she:

  • gets accommodation from the local authority for a continuous period of more than 24 hours
  • is subject to a care order (to put the child into the care of the local authority)
  • is subject to a placement order (to put the child up for adoption)
