Local authorities submit their data and carry out consistency checks. The Department for Education carries out extra checks to compare new data to data received previously.
The data collection covers all children and family social workers employed by the local authorities in England. In 2016/17, local authorities provided data about individual social workers, rather than combined data about their workforce as in previous years.
Suppression rules and disclosure control
Values of 1 or 2, and any associated percentages, are replaced with an ‘x’. Some secondary suppression may also occur to prevent any suppressed values being disclosed.
Numbers of social workers are rounded to the nearest 10 to prevent any individuals being identified. Percentages are rounded to 1 decimal place.
