How local authorities should collect data from social care services to complete the annual children in need census.

The children in need census is an annual statutory census for all local authorities. You must complete statutory censuses by law unless there’s a good reason not to.

The census covers the financial year (1 April to 31 March).

It collects data on children referred to local authority social care services because their health or development is at risk. This includes:

  • children in local-authority care (in placements in a residential home, in a foster family, or with relatives)
  • children who are getting support from their local authority’s social care services
  • children who are the subject of a child protection plan
  • unborn children who will potentially need support from social care services

Important dates

2018 to 2019 census dates:

  • census opens: Monday 1 April 2019
  • deadline for submitting data: Wednesday 31 July 2019

2019 to 2020 census dates:

  • census opens: Wednesday 1 April 2020
  • deadline for submitting data: Friday 31 July 2020

Submit your data

You should submit your data using COLLECT, our centralised data collection and management system.
