These figures, used by local authorities and the DfE, may result in some slight variances from figures calculated in previous Safeguarding Pressures reports. • The updated population figures were used to calculate the rate per 10,000 for the age group 0–17. They were also used to scale up responses to a national level, accounting for gaps where submissions were not received from every local authority. 83 This means that, where not all local authorities responded, figures are scaled to approximate national values, based on our best understanding of the returns we received. • Because this research is a sample of local authorities only, rates per 10,000 and any extrapolated numbers, which are based on responses from all local authorities at child level, may not match exactly to DfE statistical publications. • The charts presented in this report largely reflect the data at a national level, offering an overview of the trends across England as a whole. It is important to note, however, that there is considerable variation between individual local authorities. The figures representing England are based on the submissions received from local authorities. The figures have been scaled according to England’s population to create a representative national picture. 84 References Association of Directors of Children’s Services (ADCS). (2021).
