So in the four studies which have compiled the ethnicity of perpetrators, all have concluded that Asians are more likely than Whites to be grooming gang offenders, with odds ratios ranging from 4 to 40.

Note: Figures include unknowns, CEOP 2013 figures are Asian vs non-Asian.

The 2015 study by Berelowitz et. al gives the most modest picture of Asian overrepresentation among perpetrators, but still implies that Asians are 4x as likely as Whites to be grooming gang offenders.

But the same studies show Asians are disproportionately represented among offenders, that Whites are much more likely to be victims than offenders, and Asians much less likely to be victims than offenders.

And it found Whites were a larger share of victims than perpetrators. Whites were 61.1% of all victims and 91.1% of victims where ethnicity is known, whereas the similar figures for Asians were just 2.6% and 3.9% respectively.

The same study also found that for groups of offenders, where ethnicity was known, 41 were all Asian groups, 36 were all White, 15 were mixed and 1 was all Black, making Asians 13.7x overrepresented relative to Whites.

This statistic (table from original study shown below) makes Whites a slim plurality rather than a majority as is often claimed. It also makes Asians 11.4x as likely to be a grooming gang offender as Whites (assuming adult population was 7% Asian and 85% White).
