Children's social work workforce: attrition, caseload, and agency workforce

Data guidance

Published

Description

This document covers analysis and data from the attrition, caseload, and agency workforce publication 2021. 

This data is released under the terms of the Open Government License and is intended to meet at least three stars for Open Data.

The methodology should be referenced alongside this data. It provides information on the data sources, coverage and quality, as well as explaining the methods used to produce the data

Coverage

The Children’s social work workforce census covers all local authorities in England and all children and family social workers employed by those local authorities.

Kingston upon Thames and Richmond upon Thames submit a joint return each year, and the numbers are reported against Kingston upon Thames. This arrangement has no impact on regional and national totals.

Northamptonshire local authority was replaced with two new unitary authorities, North Northamptonshire and West Northamptonshire, in April 2021. Data for both unitary authorities is reported against North Northamptonshire in this publication. 

File formats and conventions

Data and metadata are provided in csv format

Where any number is shown as zero (0), the original figure submitted was zero.
x  indicates that data is not available. This may be because a local authority was unable to return a particular data item in the census, or data was not available because of concerns regarding quality.
z indicates data is not applicable.

Rounding

Figures for full-time equivalents (FTEs), rates and percentages have been rounded to one decimal place.

Attrition by time in LA

Time period
2020 to 2021
Content

Data on the breakdown of attrition by time in local authority (LA) are presented.

Time in local authority is a measure for how long a social worker has worked in their current local authority. Where time in LA is provided for leaver and attrition groups, this is how long the social worker had worked in their LA before leaving the local authority. time in local authority is not a measure of the duration an individual has been registered as a social worker.

Footnotes
  1. Time in local authority (LA) calculations are not relative to the LA-employed workforce. The proportions of time in LA groups are of the group they are in, with the full column summing to 100%.
  2. For social workers in post at 30 September, time in local authority is calculated as the time in years from when the worker started in a children's social worker role at the local authority to 30 September of the reporting year. Therefore time in local authority does not necessarily represent the amount of time an individual has been registered as a social worker, or how long they have spent in the social work profession.
  3. Components may not sum to totals due to rounding.
  4. For social workers belonging to one of the attrition groups, time in local authority is calculated as the time in years from when the worker started in a children's social worker role at the local authority, to the date they left a children's social worker role at the local authority. Therefore time in local authority does not necessarily represent the amount of time an individual has been registered as a social worker, or how long they have spent in the social work profession.

Footnotes
  1. There were 250 FTE social workers whose new role was recorded as starting before they left their original role. These social workers have been excluded from the figures.
  2. Time between roles is calculated as the time in days (including weekends and bank holidays) between a social worker leaving a role and starting a new role. For example, if a leaver ended a role on a Friday and started new role on a Monday, the time between roles is calculated as 3 days. If a leaver started their new role on the same day that they left their previous role, time between roles calculated as zero days.
  3. There were 50 FTE social workers who left their role on 30 September 2021. These workers have been excluded from the figures, as in each case their time between roles would be calculated as 0 days.
  4. Components may not sum to totals due to rounding.
