In the population as a whole more young people than older people fall into ethnic minority groups.  The most recent data are from the 2021 census.  For young people age 10-24 the proportion of those who classified themselves as falling into a category other than white in the census was just over a quarter (25.2%).  The largest groups who were not white were mixed ethnicity, Black and Asian.
