According to the NPCC - from January to September 2024, there were 1,623 (85%) white suspects of child sexual abuse, and 75 Pakistani (3.9%).
When data on abuse in institutions (schools, churches, children’s homes) and offences committed within a family are removed, the figures for group-based CSE show there were 144 (63%) white suspects, and 31 (14%) Pakistani. Bear in mind Pakistanis were 2.7% of the UK population in the 2021 census. Obviously some proportion of white suspects will also be from immigrant communities. Also the data on CSE is never anywhere close to complete. NPCC say the information on ethnicity wasn't recorded for 60% of suspects in the first nine months of 2024.
Investigations into some of the most egregious old cases like Rochdale, Rotherham and Telford also found clear evidence of systemic failures and cover-ups from police forces/social work/local councils.
