35 Note that the figures for communications data were not consistent throughout the 2018 Report. The figures
given in the 2018 Report do not give the same total number for communications requests. This reflects the
data we receive from authorities. There is a margin of error on communications data which means that the
total number of line items is inconsistent. This reflects differences in how the authorities we oversee collect
and collate these statistics. Note that the margin of error is approximately 10%.
